To this, thirty adults from 19 to 55 years old were selected. They had not periodontal treatment and no antibiotic or antimicrobial was administered during three previous months. From these individuals, sites periodontally healthy, with chronic gingivitis and/or periodontitis were analyzed. Eighteen subgingival dental biofilm samples were collected through sterile paper points being six from each tooth randomly selected, representing conditions mentioned. They were transported to Oral Microbiology laboratory, plated onto Mannitol Salt Agar (MSA) and incubated at 370C in air for 48 h. Staphylococcus spp. were identified by colonial morphology, Gram stain, catalase reaction, susceptibility to bacitracin and coagulase activity. After identification, strains were submitted to the antibiotic susceptibility test with 12 antimicrobials, based on Kirby-Bauer technique. To establish the relation between coagulase-negative Staphylococcus (CSN) presence and their infection levels and host factors, local environment and traits of diseases were used Chi-square, Mann-Whitney and Kruskal-Wallis tests to a confidence level of 95%. 86,7% subjects harbored CSN in 11,7% periodontal sites. These prevalence were 12,1% in healthy sites, 11,7% in chronic gingivitis, 13,5% in slight chronic periodontitis, 6,75% in moderate chronic periodontitis and in sites with advance chronic periodontitis was not isolated CSN, without difference among them (p = 0,672). There was no significant difference to presence and infection levels of CSN as related to host factors, local environm ent and traits of the diseases. Amongst the 74 samples of CSN isolated, the biggest resistance was observed to penicillin (55,4%), erythromycin (32,4%), tetracycline (12,16%) and clindamycin (9,4%). 5,3% of the isolates were resistant to oxacilin and methicillin. No resistance was observed to ciprofloxacin, rifampicin and vancomycin. It was concluded that staphylococci are found in low numbers in healthy or sick periodontal sites in a similar ratio. However, a trend was observed to a reduction in staphylococci occurrence toward more advanced stages of the disease. This low prevalence was not related to any variables analyzed. Susceptibility profile to antibiotics demonstrates a raised resistance to penicillin and a low one to methicillin. To erythromycin, tetracycline and clindamycin was observed a significant resistance / O objetivo deste estudo foi determinar a preval?ncia e a susceptibilidade antimicrobiana de Staphylococcus spp. em quadros de sa?de e doen?a periodontal, relacionando-as com fatores do hospedeiro, do meio ambiente local e pr?prios das doen?as. Para tanto, foram selecionados 30 indiv?duos adultos, entre 19 e 55 anos, que apresentassem s?tios periodontais saud?veis, com gengivite cr?nica e/ou periodontite cr?nica, sem tratamento periodontal, e que n?o tivessem usado antibi?tico ou antimicrobiano nos ?ltimos tr?s meses. De cada paciente foram coletadas 18 amostras de biofilme subgengival, sendo 6 por elemento dent?rio sorteado com as condi??es supracitadas. Com o aux?lio de pontas de papel absorventes est?reis, tais amostras foram coletadas do sulco gengival ou bolsa periodontal, semeadas em Agar Manitol Salgado e incubadas a 370C por 48 horas. A identifica??o de Staphylococcus spp. se deu atrav?s da colora??o de Gram, prova da catalase, susceptibilidade ? bacitracina e prova da coagulase livre Ap?s a identifica??o, as amostras foram submetidas ao teste de susceptibilidade a doze antimicrobianos, atrav?s da t?cnica de Kirby-Bauer. Para o estabelecimento da rela??o entre a presen?a de estafilococos coagulase-negativos, os n?veis de infec??o dos mesmos e os fatores do hospedeiro, do meio ambiente local e pr?prios das doen?as, foram usados os testes do Quiquadrado, Mann-Whitney e Kruskal-Wallis para um n?vel de confian?a de 95%. Quanto ? preval?ncia de estafilococos coagulase-negativos, 86,7% dos indiv?duos albergavam este microrganismo em 11,7% dos s?tios periodontais, sendo distribu?dos em 12,1% entre os saud?veis, 11,7% com gengivite cr?nica, 13,5% com periodontite cr?nica leve, 6,75% com periodontite cr?nica moderada e nenhum s?tio com periodontite cr?nica severa (p=0,672). N?o houve associa??o significativa na freq??ncia de isolamento ou nos n?veis de infec??o de ECN com fatores do hospedeiro, do meio ambiente local e pr?prios das doen?as. Dentre as 74 cepas isoladas de ECN, a maior resist?ncia observada neste estudo foi ? penicilina (55,4%), eritromicina (32,4%), tetraciclina (12,16%) e clindamicina (9,4%). Cinco v?rgula tr?s por cento das cepas foram resistentes ? oxacilina e ? meticilina. Nenhuma cepa apresentou resist?ncia aos antibi?ticos ciprofloxacina, rifampicina e vancomicina. Conclui-se, portanto, que os estafilococos est?o presentes em baixos n?meros em s?tios periodontais saud?veis e doentes numa propor??o equivalente. Por?m, uma tend?ncia foi observada em rela??o ao decr?scimo de sua ocorr?ncia em quadros mais avan?ados da doen?a periodontal. Essa baixa preval?ncia de SCN n?o esteve associada a nenhum a das vari?veis testadas nesse estudo. O perfil de susceptibilidade aos antimicrobianos demonstrou um a elevada resist?ncia ? penicilina, por?m uma baixa resist?ncia ? meticilina. Para a eritromicina, tetraciclina e clindamicina foi encontrada uma resist?ncia significativa

As alterações inflamatórias que afetam a cavidade oral e a gengiva dos felinos são frequentemente observadas na rotina médica e constituem verdadeiro desafio diagnóstico e terapêutico ao clínico. Denomina-se complexo gengivite-estomatitefaringite felina (CGEF) como sendo uma síndrome onde a apresentação clínica comum é a inflamação grave da gengiva e mucosa oral. A etiopatogênese desta doença não está totalmente elucidada mas acredita-se que seja multifatorial. As viroses têm sido implicadas como agentes etiológicos na patogenia da gengivite-estomatite crônica felina, entretanto, o mecanismo pelo qual as infecções virais participam no desenvolvimento da doença gengival nos animais afetados permanece indeterminado. A hipótese do presente estudo é de que a depleção imunológica induzida pelo lentivírus felino (FIV) aumenta o risco de ocorrência do FCV e do FHV-1 e da estomatite-gengivite em gatos. Para tanto, foram realizados 2 experimentos: o primeiro (A) foi delineado para avaliar a ocorrência do FCV e do FHV-1 na cavidade oral de 58 gatos naturalmente infectados pelo FIV ou não, com e sem gengivite, por meio da reação de polimerização em cadeia (PCR), assim como correlacionar esses achados com as subpopulações de linfócitos T CD4+, CD8+ e da razão CD4+:CD8+ e o segundo (B) foi desenvolvido para avaliar a correlação do FCV e das subpopulações de linfócitos T CD4+ com os diferentes graus de estomatite-gengivite em 35 gatos naturalmente infectados pelo FIV ou não, divididos em 2 grupos. No experimento A, pôde-se determinar que apenas o FCV está relacionado à inflamação gengival, sendo detectado em 88,9% dos gatos com gengivite. Além disso, a infecção pelo FIV promoveu aumento significativo do número de linfócitos T CD8+ (p=0,004) e diminuição da razão CD4+:CD8+ (p<0,001). No experimento B, identificou-se que a infecção pelo FIV está associada à ocorrência da infecção pelo FCV (p=0,011), à presença de gengivite (p=0,022) e ao grau de gengivite (p<0,001), sendo que os gatos infectados pelo FIV foram os que apresentaram graus mais graves de gengivite. Portanto, no grupo dos animais infectados pelo FIV pôde-se observar maior ocorrência do FCV e presença de gengivite. Adicionalmente, o grau de gengivite está diretamente associado à infecção pelo FCV (p<0,001), onde os animais positivos para este vírus apresentaram graus mais graves de gengivite. Pelo presente estudo, pôde-se concluir que a ocorrência da infecção pelo FCV está diretamente associada ao CGEF em felinos e que a ocorrência do FCV foi significativa em animais que apresentaram graus mais graves de gengivite. Além disso, os gatos que apresentaram graus mais graves de gengivite, foram os que apresentaram menores valores de linfócitos T CD4+ e maior ocorrência de infecção pelo FCV. Contudo, não é possível saber se a co-infecção pelo FIV e FCV foi responsável pelo agravamento da gengivite e da condição imunológica dos gatos ou se a disfunção do sistema imune causada pelo FIV predispôs a infecção pelo FCV, levando a piora das lesões orais. / The inflammation that affects the oral cavity and the gingiva of felines are frequently observed in the medical practice and constitute a true diagnosis and therapy challenge to the physician. This condition is referred to as feline gingivitis-stomatitis-pharyngitis complex (FGSC) and it is a syndrome in which the common clinical profile is a severe gingival and oral mucosa inflammation. The etiopathogenesis of this disease is not completely elucidated but it is believed to be multifactorial. The viruses have been involved as etiologic agents in the feline chronic gingivitis-stomatitis pathogeny, however, the mechanism through which the viral infections participate in the development of the gingival disease of the infected animals remains undetermined. The present studys hypothesis is that the immunedepletion induced by the feline lentivirus (FIV) increases the risk of development of FCV and FHV-1, and stomatitis-gingivitis in cats. In order to do so, two experiments were conducted: the first one (A) was designed to evaluate the occurrence of FCV and FHV-1 in the oral cavity of 58 cats naturally infected by FIV or not, with and without gingivitis, through polymerase chain reaction (PCR), and to correlate this findings with the subpopulations of lymphocytes T CD4+, CD8+ and the ratio of CD4+:CD8+; the second one (B) was developed to evaluate the correlation of the FCV and of the subpopulations of lymphocytes T CD4+ with the different degrees of stomatitis-gingivitis in 35 cats naturally infected by the FIV or not, divided into two groups. In the experiment A, it was possible to determine that only the FCV is related to gingivitis, being detected in 88.9% of the cats with gingivitis. Moreover, the FIV infection promoted a significant increase in the number of lymphocytes T CD8+ (p=0.004) and a decrease of the ratio CD4+:CD8+ (p<0.001). In the experiment B, the FIV infection is associated to the occurrence of gingivitis due to the FCV (p=0.011), to the presence of gingivitis (p=0.022), and to the degree of gingivitis (p<0.001), being that the FIV infected cats were the ones that presented the more severe degrees of gingivitis. Therefore, in the group of animals infected by the FIV it was possible to observe a greater occurrence of FCV and the presence of gingivitis. Additionally, the degree of gingivitis is directly related to the FCV infection (p<0.001), where the animals that tested positive for this virus presented more severe degree of gingivitis. From the present study, it was possible to conclude that the occurrence of infection due to the FCV is directly related to FGSC in felines and that the occurrence of FCV was significant in animals that presented more severe degrees of gingivitis. Moreover, the cats that presented more severe degrees of gingivitis were the ones that presented lower values of lymphocytes T CD4+ and greater occurrence of FCV infection. However, it is not possible to know whether the co-infection due to the FIV and the FCV was responsible for the worsening of the gingivitis and of the immune condition of the cats, or if the immune system dysfunction caused by the FIV predisposed the FCV infection, leading to the aggravation of the oral lesions.

Bakgrund: Individer med utländsk bakgrund tenderar ha sämre oral hälsa än svenskfödda individer. Detta kan bland annat bero på socioekonomiska faktorer såsom utbildningsnivå och kön. Invandringen till Sverige ökar och därför är det viktigt att studera nyanländas munhygienvanor samt kunskap om orala sjukdomar som karies, gingivit och parodontit för att kunna bemöta dessa individer utifrån deras behov. Syfte: Syftet med studien var att studera munhygienvanor samt kunskap gällande orala sjukdomar hos vuxna nyanlända med utländsk bakgrund. Metod: Studien är en kvantitativ tvärsnittsstudie med enkätundersökning som datainsamlingsmetod på SFI-skolor i Jönköpings kommun. Totalt 99 individer deltog i studien. Chi-två tester gjordes för jämförelse mellan grupper indelade efter utbildningsnivå. Resultat: Totalt 88,9% respektive 81,8% svarade att bakterier är en bakomliggande orsak till karies och parodontit. En statistisk signifikant skillnad visades vid jämförelse mellan högre och lägre utbildningsnivå avseende rökning som orsak till gingivit. Majoriteten av deltagarna borstade tänderna 2ggr/dagligen med fluortandkräm och 14,1% använde sig av approximalahjälpmedel 1gg/dag. Slutsats: Studiens resultat visade att deltagarna hade kunskap om orsaksfaktorer avseende karies och parodontit men bristande kunskap avseende gingivit. Deltagarna hade även goda tandborstningsvanor men bristande användning av approximalahjälpmedel och fluorpreparat. / Background: Individuals with foreign backgrounds tend to have poorer oral health than Swedishborn. This may be depending on socioeconomic factors such as education and gender. Immigration to Sweden is increasing, and therefore it is important to study oral hygiene habits and knowledge of oral diseases among newly arrived immigrants. Aim: The aim was to explore oral hygiene habits and knowledge about oral diseases of newly arrived immigrants. Method: A quantitative cross-sectional with questionnaire survey at Swedish For Immigrants’ schools in Jönköping. A total of 99 people participated in the study. Chi-two tests were made for comparison between groups by education level. Results: Totally 88.9% and 81.8% replied that bacteria are an underlying cause of caries and periodontitis. A statistically significant difference was shown between higher and lower levels of education regarding smoking as a cause of gingivitis. The majority of participants brushed their teeth 2/daily with fluoride toothpaste and 14.1% were using auxiliary aids 1/day. Conclusion: The results of the study showed that participants had knowledge about causal factors regarding caries and periodontitis, but lack of knowledge about gingivitis. The participants also had good tooth brushing habits but lacked usage of use of interproximal aids and fluoridated agents.

Objetivo: o presente estudo prospectivo avaliou a presença de microrganismos periodontopatogênicos, os níveis salivares de arginase e de HBD-2 em indivíduos com gengivite e periodontite tendo como controle indivíduos periodontalmente saudáveis, correlacionando-os aos respectivos parâmetros clínicos. Também foi avaliada expressão gênica do PAR2 crevicular em indivíduos saudáveis e com periodontite. Método: Inicialmente, foram avaliados 89 indivíduos sem doenças sistêmicas, nunca fumantes, sendo 31 saudáveis (média de idade 25,06 5,97), 27 com gengivite (média de idade 33,22 12,09) e 31 com periodontite (média de idade 52,16 11,54), todos submetidos à terapia periodontal não cirúrgica. Coleta salivar para avaliação dos níveis de arginase (quantificada por meio de espectrofotometria) foi realizada no início do tratamento em todos os indivíduos, e naqueles com gengivite e periodontite respectivamente em 30 e 50 dias pós-tratamento. Avaliação clínica de profundidade de sondagem, perda de inserção clínica e índices de placa e gengival e microbiana (Campylobacter rectus, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tanerella forsythia, Treponema denticola e Prevotella intermedia) foram também avaliados nos mesmos tempos. Dentre os 89 indivíduos, amostras do fluido gengival foram coletadas em 10 indivíduos saudáveis e 10 com periodontite para mensuração da atividade do PAR2 crevicular por meio de RT-PCR. Como esta relação foi positiva, foi verificada a quantidade de HBD-2 salivar por meio de ELISA de todos os 89 indivíduos e sua relação com os parâmetros clínicos e microbiológicos. A significância de todas as relações e quantificações foi analisada por meio de testes estatísticos apropriados. Resultados: foi observada uma melhora estatisticamente significativa dos parâmetros clínicos e microbianos após o tratamento periodontal. A arginase salivar estava significativamente mais elevada nos indivíduos com periodontite em relação àqueles com gengivite, e nestes em relação aos saudáveis. O tratamento periodontal promoveu melhora dos indivíduos doentes, cujos parâmetros avaliados tornaram-se estatisticamente semelhantes aos dos saudáveis. Houve maior atividade do PAR2 nos 10 indivíduos com periodontite em relação aos saudáveis e, após o tratamento, houve uma redução estatisticamente significativa deste parâmetro. Por fim, foram observados níveis estatisticamente mais elevados de HBD-2 salivar nos indivíduos com periodontite comparados àqueles com gengivite e aos saudáveis. Não foi possível observar uma correlação entre HBD-2 salivar e os microrganismos analisados. Conclusões: com base nos resultados observados, podemos concluir que: a arginase salivar está significativamente aumentada nos indivíduos periodontalmente comprometidos em relação aos saudáveis; o tratamento periodontal promoveu melhora dos indivíduos doentes em relação aos parâmetros avaliados; indivíduos com periodontite têm maior expressão gênica do PAR2 do que aqueles saudáveis e o tratamento tornou esta expressão semelhante nos dois grupos; indivíduos com periodontite têm níveis estatisticamente mais significativos de HBD-2 salivar do que aqueles saudáveis e aqueles com gengivite; a saliva parece ser uma ferramenta útil para o diagnóstico periodontal e para o monitoramento da eficácia do tratamento periodontal. / Objectives: This prospective study evaluated the presence of periodontopathogenics microorganisms, as it also examined the salivary levels of arginase and HBD-2 from subjects with gingivitis and periodontitis and periodontally healthy subjects as controls, correlating them to relevant clinical parameters. The gene expression of PAR2 crevicular in healthy subjects and periodontitis was also assessed. Methods: Initially, 89 individuals without systemic diseases, who were never smokers, were evaluated. Out of the 89, 31 were healthy subjects (average age 25.06 5.97), 27 have gingivitis (average age 33.22 12.09) and 31 were with periodontitis (average age 52.16 11.54), all underwent nonsurgical periodontal therapy. Saliva was collected for assessing levels of arginase at baseline in all subjects (quantified by spectrophotometry), and repeated on those with gingivitis and periodontitis respectively at 30 and 50 days post treatment. Clinical evaluation of probing depth, clinical attachment loss, both plaque and gingival index as well as microbial evaluation (Campylobacter rectus, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tanerella forsythia, Prevotella intermedia and Treponema denticola) were also assessed at the same time. Among the 89 individuals, gingival fluid samples were collected from 10 healthy ones and from 10 with periodontitis to measure crevicular PAR2 activity by RT-PCR. As the results came out positive, the amount of HBD-2 salivary was tested by ELISA for all 89 subjects assessing its relationship with clinical and microbiological parameters. The significance of all relationships and quantifications were analyzed using appropriate statistical tests. Results: we observed a statistically significant improvement of clinical and microbial parameters after periodontal treatment. Salivary arginase was significantly higher in subjects with periodontitis than in those with gingivitis, and those with gingivitis had higher results than the healthy ones. Periodontal treatment promoted improvement of the non-healthy individuals whose parameters became statistically similar to the healthy ones. There was a greater PAR2 activity in 10 individuals with periodontal disease compared to healthy ones, and after treatment the results showed a statistically significant reduction in this parameter. Finally, we observed statistically higher levels of salivary HBD-2 in individuals with periodontitis compared to both those with gingivitis and those individuals in the healthy group. It has not been possible to observe a correlation between HBD-2 and salivary microorganisms analyzed. Conclusion: Based on the observed results, we can conclude that salivary arginase is significantly increased in periodontally compromised individuals relative to the healthy ones; periodontal treatment promoted improvement of individuals in relation to the assessed parameters; individuals with periodontitis have higher gene expression of PAR2 than those healthy and the periodontal treatment brought similar results to both groups; individuals with periodontitis have statistically more significant levels of salivary HBD-2 than those with healthy gums and gingivitis; and, finally, saliva, besides being useful for periodontal diagnosis, appears to be also helpful for monitoring efficacy of periodontal treatment.

Study Hypothesis: People with diabetes when submitted to gingival treatment may have different perceptions and have an impact on their quality of life. Objectives: This study evaluated the effect of gingival treatment on quality of life related to oral health in type-2 diabetic patients (DM2). Methods: 150 patients were included in this study, 100 with gingivitis divided into two groups: diabetes (n=50) and control group (systemically healthy, n=50) in addition to a negative control group (systemically healthy and gingival health, n=50). The groups received professional treatment and oral hygiene instruction. Then the subjects were randomly divided into essential oils (Listerine total care, n=25) or placebo (n=25), six randomized groups total. To assess the impact of the Quality of Life Factor - QoL (OHQoL-UK questionnaire) and its interaction with DM (diabetic or non-diabetic), with treatment (essential oils or placebo) and with time bases (baseline and three months) in clinical factors (plaque and gingival indexes - PI, GI and probing depth - PD), microbiological factors (Porphyromonas gingivalis - Pg, Aggregatibacter actinomycetemcomitans - Aa, Tannerella forsythia - Tf and total bacterial load - TBL), immunological (interleukin 1&#946;-IL-1&#946;) and breath levels (volatile sulfur compound levels - VSC), we used multiple linear regression analysis. Comparative analyzes were performed intra-group (initial vs. final) and inter-group (in each experimental time) using the Bio Estat 5.0 and SPSS 14.0 software. Results: The value obtained in Cronbachs alpha test (0.971), the significance of the Bartletts test (p&#706;0,0001) and the value of 0.935 for KMO test indicated good agreement, correlation variables and adaptation of the size of the instruments sample that OHQoL was shown to be latent when subjected to factor analysis. The Multiple Linear Regression Analysis detected impact between QoL and treatment in GI (p=0.03) between the QoL and TBL (p=0.03) and between QoL and treatment in VSC (p=0.011). Conclusion: Participants with diabetes and gum disease who reported improvement in quality of life tend to have better periodontal health and breath indicators, especially when a daily rinse with essential oils mouthrinse is executed. / Hipótese do estudo: Indivíduos com diabetes quando submetidos ao tratamento gengival podem apresentar diferentes percepções e gerar impacto sobre sua qualidade de vida. Objetivos: Este estudo avaliou o efeito do tratamento gengival sobre a qualidade de vida relacionada à saúde bucal de indivíduos diabéticos (DM). Metodologia: Foram incluídos no presente estudo 150 indivíduos, sendo cem com gengivite divididos em dois grupos: diabetes (n=50) e Controle (sistemicamente saudável, n=50) em adição a um grupo controle negativo (sistemicamente saudável e com saúde gengival, n=50). Os grupos receberam profilaxia profissional e instrução de higiene bucal. Em seguida os indivíduos foram aleatoriamente distribuídos em óleos essenciais OE (Listerine cuidado total, n=25) ou placebo (n=25), totalizando seis grupos aleatorizados. Para avaliar o impacto do Fator de Qualidade de Vida - FQV (questionário OHQoL-UK), bem como sua interação com DM (diabético ou não diabético), com tratamento (óleos essenciais ou placebo) e com o tempo (baseline e três meses), nos fatores clínicos (índices de placa e gengival IP, IG e profundidade de sondagem PS), microbiológicos (Porphyromonas gingivalis - Pg, Aggregatibacter actinomycetemcomitans - Aa, Tannerella forsythia - Tf e carga bacteriana total - CBT), imunológicos (interleucina 1&#946; IL-1&#946;) e halitométricos (níveis de compostos sulforados voláteis CSV), foram utilizados modelos de Regressão Linear Múltipla. Análises comparativas foram realizadas intra-grupo (inicial vs. final) e inter-grupos (em cada tempo experimental) com auxílio do software Bio Estat 5.0 e SPSS 14.0. Resultados: O valor obtido em Alpha de Cronbach (0,971), a significância do teste de Bartlett (p&#706;0,0001) e o valor de 0,935 para o teste KMO indicaram boa consistência, correlação de variáveis e adequação do tamanho da amostra do instrumento OHQoL que foi demonstrado estar latente quando submetido a uma análise fatorial. O Modelo de Regressão Linear Múltipla detectou impacto entre o FQV e o tratamento em IG (p=0,03), entre o FQV e CBT (p=0,03) e entre FQV e tratamento com OE em CSV (p=0,011). Conclusão: Participantes com diabetes e gengivite que relataram melhora na qualidade de vida tendem a apresentar melhores indicadores de saúde periodontal e hálito, principalmente quando fizeram uso diário de solução à base de óleos essenciais.

Magister Chirurgiae Dentium (MChD) / The dental clinic of the University of the Western Cape provides oral health care for many preschool children. The clinical observation was that these children presented with rampant dental caries. A recent report compi1ed by an international Joint Working Group of the Internationale Dental Federation and the World Health Organisation identified the changes in oral health in children and factors associated with these changes. South Africa presents a unique opportuni ty to study the oral health status of different ethnic and socio-economic groups. A review of the relevant literature indicated that there was a lack of published data, especially on the oral health status of preschool children. A study was designed to investigate the oral health status of a selected group of preschool children ages 2-6 years in the Western Cape. The examinations were conducted at twelve different créches by two calibrated examiners. The examinees' weight and height were also measured. The data was recorded on a revised World Health Organization Basic Oral Health Assessment form. A total of 547 children were examined with an almost equal distribution of males and females. Only 18% of the sample had a compl ete sound primary dentition, dmft = O. The mean dmft was 5.37 which ranged from 2.73 for the 2 year age group to 7.01 for the 5 year age group. The mean dt of 4.09 made up 76% of the dmft, the mean mt of 1.22 made up 23% and the ft was negligible. Seventy-eight percent of the sample had decayed teeth present and 28% had missing teeth recorded. The treatment chosen by or for these children appeared to be extractions. Observations of extensively decayed teeth and the high prevalence of dento-alveolar abscesses suggested that this treatment was of an emergency nature. There was much unmet treatment as only 22% of subjects were free of decay and those with decayed teeth present had an average of 5. The dmft distribution showed 48% had a dmft.)5. There was a statistically significant linear association between the dmf and age for all the tooth types except the cani nes. There was no significant difference in caries prevalence between males and females. The phenomenon of bilateral symmetrical occurrence of dental caries in the primary dentition was demonstrated in the present study. The maxillary central incisors were the most frequently affected teeth (55%), followed by the mandibular second molars (47%) and maxillary second molars (42%). This is contrary to the findings in European communities where the primary second molars are the most susceptible tooth types. The present study found the fifth year of 1ife to be the critical one for the primary dentition. It was at this age that the greatest increment in dmft was observed, the greatest decrease in the number of caries-free subjects, more than a twofold increase in rampant caries, and a twofold increase in the number of subjects with dento-a1veo1ar abscesses. Few hard tissue anomalies were recorded. Localized enamel hypoplasia was quite common especially of the upper incisors and second molars. Most children claimed their teeth were brushed at least once a day. But soft deposits were present in almost all age groups in all the segments. Sixty percent of the sample had the sole responsibility of brushing their own teeth with no assistance from their parents. Parental assistance with toothbrushing was limited to the younger age group. In the present study soft deposits and gingivitis were recorded mostly on the buccal of the upper posterior segments and on the lingual of the lower posterior segments. The anterior segmentshad less plaque than the posterior segments. Thi s may be due to children finding it easier to brush anteriorly than posteriorly when they do brush. Also, the other areas are less accessible and require greater manipulative skill. There was a weak correlation between the total soft deposits and total gingivits. Although 60% of the sample had six segments of soft deposits present, only 4% had )six segments of gingivitis present. However, it was found that the higher the number of segments of soft deposits present, the greater the tendency for the presence of gingivitis. The association between dmft and soft deposits was not significant but between dmft and gingivitis was significant. This may be more preci se as these two are both cumulative measures. Soft tissue lesions were generally uncommon in this age group. The children in this community were generally lighter in weight and shorter in height compared to the NCHS (1979) percentiles. Recommendations regarding ways of redressing the obviously inadequate general and oral health of this sample of children were made.

This retrospective cross-sectional study aimed to explore interactions between signs of periodontal inflammation and systemic parameters in athletes. Members of German squads with available data on sports medical and oral examination were included. Groups were divided by gingival inflammation (median of papillary bleeding index, PBI median) and signs of periodontitis (Periodontal Screening Index, PSI 3). Age, gender, anthropometry, blood parameters, echocardiography, sports performance on ergometer, and maximal aerobic capacity (VO2max) were evaluated. Eighty-five athletes (f = 51%, 20.6 3.5 years) were included (PBI < 0.42: 45%; PSI 3: 38%). Most associations were not statistically significant. Significant group differences were found for body fat percentage and body mass index. All blood parameters were in reference ranges. Minor differences in hematocrit, hemoglobin, basophils, erythrocyte sedimentation rates, urea, and HDL cholesterol were found for PBI, in uric acid for PSI. Echocardiographic parameters (n = 40) did not show any associations. Athletes with PSI 3 had lower VO2max values (55.9 6.7 mL/min/kg vs. 59.3 7.0 mL/min/kg; p = 0.03). In exercise tests (n = 30), athletes with PBI < 0.42 achieved higher relative maximal load on the cycling ergometer (5.0 0.5 W/kg vs. 4.4 0.3 W/kg; p = 0.03). Despite the limitations of this study, potential associations between signs of periodontal inflammation and body composition, blood parameters, and performance were identified. Further studies on the systemic impact of oral inflammation in athletes, especially regarding performance, are necessary.

INTRODUÇÃO: Com a melhora do prognóstico nos pacientes com lúpus eritematoso sistêmico juvenil novas recomendações são necessárias na reumatologia pediátrica, como avaliação da saúde bucal e do sistema mastigatório. O objetivo deste estudo é avaliar o comprometimento orofacial nos pacientes com lúpus eritematoso sistêmico juvenil e grupo controle, e avaliar possíveis associações entre o comprometimento orofacial e manifestações clínicas, exames laboratoriais e terapias da doença. MÉTODOS: Entre março de 2004 e julho de 2005 foram avaliados 48 pacientes com diagnóstico de lúpus eritematoso sistêmico juvenil, atendidos na Unidade de Reumatologia Pediátrica do ICr-HC-FMUSP. O grupo controle incluiu 48 crianças e adolescentes saudáveis atendidos na Divisão de Odontologia do HC-FMUSP. A pesquisa incluiu avaliação de dados sócio-demográficos, manifestações clínicas, exames laboratoriais, atividade da doença (SLEDAI), dano cumulativo (SLICC/ACR-DI) e terapias da doença. A avaliação orofacial incluiu questionário de anamnese, índice CPO-D, índice de placa, índice de sangramento gengival, relação dentária, perfil facial, índice de Helkimo e avaliação da articulação temporomandibular através da radiografia panorâmica de face em todos os pacientes e tomografia computadorizada apenas nos casos com achatamento e/ou destruição dos côndilos mandibulares. RESULTADOS: Os dois grupos foram homogêneos com relação à faixa etária, distribuição por gênero e classe sócio-econômica. A idade dos pacientes com lúpus eritematoso sistêmico juvenil variou de 87 a 218 meses (média de 161,9±38,4) e do grupo controle de 78 a 254 meses (média de 154,4±45,8; p=0,384). As medianas dos índices de placa e de sangramento gengival nos pacientes com lúpus eritematoso sistêmico juvenil foram superiores em relação aos controles (61,5X38,1; p=0,003 e 26,0X15,95; p=0,014). O índice de disfunção clínica e o índice de mobilidade mandibular mostraram-se mais alterados nos pacientes com LESJ versus controles (p=0,002, p=0,025). Correlação linear estatística foi evidenciada entre: tempo de doença e índice de sangramento gengival (p=0,017; r=0,11), dose cumulativa de prednisona e índice de placa (p=0,010, r=0,385) e dose cumulativa de prednisona e índice de sangramento gengival (p=0,001, r=0,02). A mediana do índice de mobilidade mandibular foi superior nos pacientes com lúpus eritematoso sistêmico juvenil em uso de um ou mais imunossupressores em relação aos que não utilizaram estas drogas (p=0). Apenas dois pacientes apresentaram radiografia panorâmica com achatamento e/ou destruição dos côndilos mandibulares e na tomografia computadorizada de ATM os achados foram: redução do espaço articular bilateralmente, erosões dos platôs articulares com aplainamento dos côndilos sugestivo de necrose avascular da articulação temporomandibular. CONCLUSÕES: Os pacientes com lúpus eritematoso sistêmico juvenil apresentaram uma precária higiene oral, maior freqüência de gengivite e disfunção da articulação temporomandibular em relação ao grupo controle. Os pacientes com maior tempo de doença e maior dose cumulativa de prednisona tiveram maior freqüência de gengivite e os que utilizaram imunossupressores apresentaram disfunção da articulação temporomandibular / INTRODUCTION: Given the enhanced prognosis of patients with juvenile systemic lupus erythematosus, new recommendations are necessary in pediatric rheumatology, such as the analysis of oral health and the masticatory system. The aim of this study was to compare dental and facial conditions of patients with juvenile systemic lupus erythematosus and a control group, and to evaluate a potential relationship between dental and facial endangering and clinical manifestations, laboratory tests and therapies for the disease. PATIENTS AND METHODS: A total of 48 children and adolescents with juvenile systemic lupus erythematosus attending the Pediatric Rheumatology Unit of the Children\'s Institute of our University Hospital were studied between January 2004 and July 2005. The control group included 48 healthy children and adolescents that were selected from the Odontology Division of our University Hospital. The search included the analysis of social and demographic data, clinical manifestations, laboratory tests, juvenile systemic lupus erythematosus disease activity and cumulative damage (using the SLEDAI and the SLICC/ACR-DI), and therapies. The dental and facial examination included the anamnesis questionnaire, DMFT index, plaque and gengival bleeding index, dental relationship, facial profile, Helkimo\'s index and evaluation of the temporomandibular joint through a radiographic panoramic examination of all patients and a computer tomography on those with flattening and/or destruction of the mandibular condyles. RESULTS: The two groups were homogeneous regarding age, gender and social-economic class. The age of the juvenile systemic lupus erythematosus patients ranged from 87 to 218 months (mean of 161.9±38.4) and of the control group from 78 a 254 months (mean of 154.4±45.8; p=0.384). The medians of the plaque and gingival bleeding indexes were higher in juvenile systemic lupus erythematosus patients than in the control group (61.5X38.10; p=0.003 and 26.0X15.95; p=0.014). The indexes of clinical dysfunction and mandibular mobility were higher in juvenile systemic lupus erythematosus patients versus the control group (p=0,002, p=0,025). A linear statistical correlation was evidenced between: juvenile systemic lupus erythematosus duration and the gingival bleeding index (p=0.017; r=0.11), cumulative dose of prednisone and the plaque index (p=0,010; r=0.385) and cumulative dose of prednisone and the gingival bleeding index (p=0.001, r=0.02). The median of the mandibular mobility index was higher in juvenile systemic lupus erythematosus patients that used at least one imunossupressive drugs compared with those that didn\'t use this medication (p=0). Only two patients showed a panoramic radiography with flattening and/or destruction of the mandibular condyles. The computer tomography revealed: narrowing of joint spaces bilaterally and erosions of joints plateaus with flattening of condyles that suggested avascular necrosis of temporomandibular joint. CONCLUSIONS: Juvenile systemic lupus erythematosus patients presented poor oral hygiene, higher incidence of gingivitis and temporomandibular joint dysfunction compared to the control group. Patients with longer disease duration and higher cumulative dose of prednisone had a greater incidence of gingivitis, and those who used imunossupressives drugs showed temporomandibular joint dysfunction

O objetivo do presente estudo foi avaliar a relação da gengivite, através da prevalência de sangramento gengival e de cálculo dentário, com fatores associados, em estudantes de 12 anos de escolas públicas da zona urbana de Quito (Equador). Para tanto, selecionou-se uma amostra representativa dessa população, e constituiu-se uma equipe para a avaliação. Tal equipe era composta por três grupos contemplando dois examinadores, dois anotadores e dois monitores de campo. Estes foram reorganizados segundo a divisão geográfica de Quito - regiões Norte, Central e Sul -, e pelas respectivas escolas. A prevalência de sangramento gengival, ajustada pelo desenho do estudo, foi de 92%, enquanto a prevalência de cálculo dentário foi de 69,9%. Dos estudantes examinados, 49% apresentavam sangramento gengival nos seis sextantes, e 5,6% apresentavam cálculo dentário também em todos os sextantes. Em contrapartida, 6,8% dos estudantes apresentavam saúde periodontal, ou seja, não apresentavam nenhum sextante com sangramento, e 26,5% não apresentavam cálculo dentário. Os resultados obtidos permitiram as seguintes conclusões: Dos fatores associados com a gengivite, podemos observar que houve associação significativa entre sangramento gengival e escolaridade dos pais, bem como maloclusão. Além disso, houve associação significativa entre cálculo dentário e escolaridade dos pais, bem como cárie dentária. / The objective of this study was to examine the prevalence of gingival bleeding and dental calculus among 12-year-old students enrolled in public schools in the urban zone of Quito (Ecuador). A representative sample was selected. A team of examiners, scorers, and field monitors was trained for the evaluation. The teams were assigned to geographic zones of the City of Quito to assess students of the selected schools. The prevalence rate of gingival bleeding was 92% and the prevalence rate of dental calculus was 69.9%. The 49% of the students in our sample suffered from gingival bleeding in all sextants, and 5.6% presented dental calculus in all sextants. Only 6.8% of the students presented gingival health and 26.5% had no dental calculus. The results obtained allowed the following conclusions: The prevalence of gingival bleeding in students of 12 years of public schools in the urban zone of the city of Quito (Ecuador) was quite high. There was a significant association between gingival bleeding and parental schooling, as well as malocclusion. There was a significant association between dental calculus and parental schooling, as well as dental caries.

Objetivo: O impacto da artrite idiopática juvenil (AIJ) nas doenças periodontais é controverso, provavelmente devido à heterogeneidade de sexo e idade. Assim sendo, avaliou-se uma população homogênea com AIJ em relação às doenças periodontais e dislipidemia. Métodos: Trinta e cinco pacientes púberes e pós-púberes com AIJ do sexo feminino e 35 controles saudáveis comparáveis em relação ao sexo e idade foram avaliadas de acordo com dados demográficos, avaliação periodontal e dental completa, lipoproteínas em jejum e anticorpos antilipoproteína lipase. Foram avaliados também os escores da AIJ, exames laboratoriais, raio-X panorâmico e tratamento. Resultados: A idade atual foi semelhante nas pacientes e controles (11,90 ± 2,0 vs. 12,50 ± 3,0 anos; p=0,289). As avaliações periodontais mostraram que índice gengival, índice de placa, índice de sangramento e índices clínicos de inserção dentária foram semelhantes em pacientes e controles (p > 0,05), com exceção do aumento gengival no primeiro grupo (p < 0,0001). Análise realizada entre os pacientes com e sem gengivite mostrou que o uso de ciclosporina foi mais frequentemente observado nas pacientes com gengivite (37% vs. 0%; p=0,01), enquanto não foram evidenciadas diferenças demográficas, escores da AIJ, marcadores inflamatórios e perfil lipídico em ambos os grupos. Destacam-se que parâmetros de avaliação periodontal foram correlacionados com os escores da AIJ [índice gengival (IG) e Escola Paulista de Medicina - Range of Motion (EPM-ROM) (rs=+0,392; p=0,024); índice gengival (IG) e Childhood Health Assessment Questionnaire (CHAQ) (rs=+0,402; p=0,020); e índice de placa (IP) e escala visual analógica (EVA) do médico (rs=+0,430; p=0,013)]. Além disso, a avaliação odontológica demonstrou que os escores de atividade da AIJ apresentaram correlação positiva com dentes cariados, perdidos e obturados (CPO-D) com: escore de atividade da doença (JADAS27) (rs=+0,364; p=0,037), EVA do médico (rs=+0,401; p=0,021) e EVA do paciente (rs=+0,364; p=0,037). Conclusão: Demonstrou-se que doenças periodontais e dentais são semelhantes em AIJ e controles, e que estas condições são influenciadas por parâmetros da doença / Objective: The impact of juvenile idiopathic arthritis (JIA) in periodontal diseases is controversial probably due to sex and age heterogeneity. We therefore evaluated a homogeneous JIA population about periodontal diseases and dyslipidemia. Methods: Thirty-five female pubertal and post-pubertal JIA patients and thirty-five sex/age comparable healthy controls were evaluated according to demographic data, complete periodontal and dental evaluation, fasting lipoproteins, and anti-lipoprotein lipase antibodies. JIA scores, laboratorial tests, panoramic X-ray, and treatment were also assessed. Results: Current age was similar in JIA patients and controls (11.90 ± 2.0 vs. 12.50 ± 3.0 years, p=0.289). Complete periodontal assessments revealed that gingival index, dental plaque, gingival bleeding, and clinical dental attachment indices were alike in JIA patients and controls (p > 0.05), except for gingival enlargement in former group (p < 0.0001). Further analysis of patients with and without gingivitis revealed that cyclosporine use was more often observed in JIA patients with gingivitis (37% vs. 0%, p=0.01), whereas no differences were evidenced in demographic, JIA scores, inflammatory markers, and lipid profile in both groups. Of note, parameters of periodontal assessment were correlated with JIA scores [gingival index (GI) and \"Escola Paulista de Medicina\" - Range of Motion (EPM-ROM) (rs=+0.392, p=0.024); gingival index (GI) and Childhood Health Assessment Questionnaire (CHAQ) (rs=+0.402, p=0.020); and plaque index (PI) and physician visual analog scale (VAS) (rs=+0.430, p=0.013)]. In addition, evaluation of dental assessment demonstrated that JIA activity scores had positive correlation with decayed, missing, and filled teeth (DMF-T) and: juvenile arthritis disease activity score (JADAS-27) (rs=+0.364, p=0.037), physician VAS (rs=+0.401, p =0.021) and patient VAS (rs=+0.364, p=0.037). Conclusion: We demonstrated that periodontal and dental diseases were similar in JIA and controls, and we also showed that these conditions are influenced by disease parameters
