This discussion evolves a reflection about the perspectives of consolidation of the FHP as well as the possible advancements of the Brazilian Unified Health System (SUS - Sistema ?nico de Sa?de). The target population was composed of dentists from the FHP of Rio Grande do Norte. Thus we performed twenty-one interviews orientated by a semi-structured guidebook with open questions and identification data. We opted for recording the speech of all the professionals in order to ensure the accuracy of the information gathered. The main results found were: predominance in the female gender; the majority of dentists has no post graduation courses; in those few cases of dentists with some post-graduation a lack of correlation with Public or Collective Health was observed; the dentists interviewed present a profile directed to clinical activities; the dentists used to develop basic restorative and periodontic treatment, simple surgeries and educative and preventive activities, even though the last two ones are carried out in an extremely traditional way (lectures and topical application of fluoride). In addition, as biggest difficulties to manage the work dentists pointed out the lack of permanent and consumer material, inadequate infrastructure, no transport to take them to distant places, no integration with the Health Family Team, technical difficulty such to perform educative and preventive activities as to provide adequate service to a repressed lawsuit. The results indicate the existence of a necessity to lead them to reflect and redirect their practices. In order to reach this aim it must be considered as initial measure the investment and encouragement toward to permanent education as well as a close follow-up and evaluation of the actions developed by them / A presente investiga??o tem como objetivo analisar o perfil de atua??o de cirurgi?es-dentistas inseridos no Programa de Sa?de da Fam?lia (PSF) de munic?pios do Rio Grande do Norte, buscando conhecer e compreender a maneira como estes experienciam o trabalho que desenvolvem neste Programa. Esta discuss?o envolve uma reflex?o a respeito das perspectivas da consolida??o do PSF e dos avan?os poss?veis do Sistema ?nico de Sa?de no pa?s. A popula??o que fez parte da pesquisa foi composta de Cirurgi?es-Dentistas que estavam trabalhando no PSF no Estado do Rio Grande do Norte. Foram realizadas 21 entrevistas orientadas por um roteiro semi-estruturado com perguntas abertas e composta de dados de identifica??o. Optou-se por gravar a fala dos profissionais, tendo em vista uma melhor fidelidade da coleta de informa??es. Os principais resultados encontrados foram: predomin?ncia do sexo feminino; maioria dos entrevistados sem p?s-gradua??o, sendo que, aqueles que a possuem, n?o h? rela??o com a sa?de p?blica ou coletiva; os cirurgi?es-dentistas t?m perfil voltado para a atividade cl?nica; e os mesmos desenvolviam atividades b?sicas de dent?stica, periodontia b?sica, cirurgia simples e atividades preventivas e educativas, embora realizadas de maneira tradicional (palestras e aplica??o de fl?or). Apontaram como dificuldades a falta de materiais, estrutura f?sica inadequada, falta de transporte para localidades distantes, falta de integra??o com a Equipe de Sa?de da Fam?lia, dificuldade t?cnica para realiza??o de atividades educativas e preventivas e de atendimento ? demanda reprimida. Os resultados apontam que h? necessidade de motiv?-los a refletir e redirecionar as suas pr?ticas, tendo como medida inicial o investimento e est?mulo ? educa??o permanente e um monitoramento e avalia??o das a??es desenvolvidas pelos mesmos

It was developed among adults with ages from 20 to 59 years, low social and economic conditions, at Natal RN, Brazil. The Free-words Association Test was applied as the instrument of data collection and a semi-structured interview with the smokers and non-smokers, besides a structured interview with smokers, non-smokers and ex-smokers. All data was analyzed by the descriptive statistics using the Analysis of Content Technique of the thematic kind and by the softwares ALCESTE and EVOC 2000. Elaborations about smoking were marked by social, cultural and historical dimension, however they showed sensibility to changes and revealed positive and negative aspects of the habit. The analysis of the semi-structured interviews showed the following categories and under-categories respectively: Initiation of the habit (Friends and Family and Appreciation and Beauty); Psychosocial Implications of smoking (Personal relationship, Work and Financial); Behavior when facing smoking (Positive, Negative and Neutral); Smoking Effects (Smokers? health and the other people health); Description about oral diseases ( Bad breath, Oral cancer and Dental problems); Smoking treatment (Physician and psychological, Supernatural and Difficulties). ALCESTE analysis presented 4 classes: Ambivalence between pleasure and get ill, Smoking as a trouble and danger to society, Social discrimination of smokers and Mouth as a place of reaffirmation of the discrimination. Those helped us to understand the psychosocial repercussion of the habit. On the social representation structure we identified as a probable central nucleus of the smoker group the categories Pleasure and Bad to the health and as peripheral elements Alcoholic Drink, Financial damage and Nervousness. For the non-smoker group the category Bad to the health comes first and Stop Smoking comes as a peripheral element. Finally, we hope that the knowledge of these representations can contribute to plan and/or to rethink over the professional practices and public policies related to smoking. Besides that, for an amplified comprehension of the study object the discussions over the identified representations should be deepen and amplified to other population and social groups / O presente estudo teve por objetivo apreender os significados do tabagismo na din?mica social, baseando-se na Teoria das Representa??es Sociais. O estudo foi desenvolvido com adultos, com idade de 20 a 59 anos, de baixa condi??o s?cio-econ?mica, em Natal-RN. Como instrumentos de coleta de dados foram utilizados o Teste de Associa??o Livre de Palavras e uma entrevista semi-estruturada, realizadas com fumantes e n?o-fumantes, al?m de uma entrevista estruturada, realizada com fumantes, n?o-fumantes e ex-fumantes, que foram analisadas atrav?s da estat?stica descritiva, da T?cnica de An?lise de Conte?do do tipo tem?tica, e dos Programas ALCESTE e EVOC 2000. As elabora??es sobre o tabagismo foram marcadas pela dimens?o social, cultural e hist?rica, mostrando-se, por?m, sens?veis ?s mudan?as, e revelaram aspectos positivos e negativos do h?bito. Na an?lise das entrevistas semi-estruturadas apreendemos as seguintes categorias e subcategorias respectivamente: Inicia??o do h?bito (Amigos e fam?lia e Admira??o e beleza); Implica??es psicossociais do tabagismo (Relacionamento pessoal, Trabalho e Financeira); Posicionamento frente ao tabagismo (Positivo, Negativo e Neutro); Efeitos do tabagismo (A sa?de dos fumantes e A sa?de dos outros); Descri??es sobre as doen?as bucais (Mau h?lito, C?ncer de boca e Problemas dent?rios); Tratamento do tabagismo (M?dico-psicol?gico, Sobrenatural e Dificuldades). A an?lise do ALCESTE revelou 4 Classes: Ambival?ncia entre o prazer e o adoecer, O tabagismo como inc?modo e perigo ? sociedade, A discrimina??o social do fumante e A boca como local de reafirma??o da discrimina??o, e nos auxiliou a compreender as repercuss?es psicossociais do h?bito. Na estrutura das representa??es sociais, identificamos como prov?vel n?cleo central do grupo fumante as categorias Prazer e Prejudica a sa?de e como elementos perif?ricos Bebida alco?lica, Preju?zo financeiro e Nervosismo. Para o grupo n?o-fumante, a categoria Prejudica a sa?de emerge na centralidade e Parar de fumar surge como elemento perif?rico. Finalmente, esperamos que o conhecimento destas representa??es venha contribuir para planejar e/ou repensar as pr?ticas profissionais e pol?ticas p?blicas relacionadas ao tabagismo. Al?m disso, para uma compreens?o mais ampla do objeto de estudo, as discuss?es sobre as representa??es identificadas necessitam ser aprofundadas e ampliadas a outras popula??es e grupos sociais

The knowledge about the role of periodontal disease as a risk factor to cardiovascular disease from dentistry and physicians is very important to try to eliminate this risk factor. The aim of this work was to investigate, using a questionary, if physicians and dentistry are aware about this relationship and if they think that it is important. These forms were distributed in 4 groups: cardiologists (n=90), physicians from other specialist (POS) (n=110), periodontists (n=35) and dentistry from other specialist (DOE) (n=85). We had a loss off 32,4% of the total sample due to a lack of response of some professionals. Our results showed that all cardiologists, all dentists and 68,2% of POE said that they had gotten information about the relationship between periodontal and cardiovascular disease, and just 6 POS don t believe that this relationship can occur. When questioned if, even when a periodontal disease is diagnosed, there is a habit to treat or orient the patient for treatment, 29,5% of cardiologists answered no, 25,5% of POE also answered that they did not orient and only 1 DOE answered that he did not treat nor orient. All periodontists said that treat their patients when periodontal disease was identify. The physicians seem not to find important the relationship that exist between periodontal and cardiovascular diseases and the dentistry have shown a good knowledge about this subject. Maybe, if physicians and dentistry work together, the incidence of cardiovascular disease decreases / A poss?vel rela??o entre a doen?a periodontal e a cardiovascular ? uma realidade nos dias atuais. O conhecimento sobre o papel da doen?a periodontal como fator de risco para doen?as cardiovasculares por cirurgi?es-dentistas e m?dicos ? muito importante na tentativa de eliminar esse fator de risco. O objetivo deste trabalho foi de investigar, atrav?s de um question?rio, se m?dicos e dentistas t?m conhecimento sobre tal rela??o e se consideram importante. Os question?rios foram distribu?dos em 4 grupos: cardiologistas (n=90), m?dicos de outras especialidades (MOE) (n=110), periodontistas (n=35) e cirurgi?es-dentistas de outras especialidades (CDOE) (n=85). Tivemos uma perda de 32,4% da amostra total devido a uma n?o resposta de alguns profissionais. Nossos resultados mostraram que todos os cardiologistas, todos os CDs e 68,2% dos MOE disseram ter obtido informa??o sobre a rela??o entre a doen?a periodontal e cardiovascular, e apenas 6 MOE n?o acreditam que essa rela??o possa existir. Quando questionados se, mesmo ao ser diagnosticada a doen?a periodontal, existia o h?bito de tratar ou encaminhar os pacientes para tratamento, 29,5% dos cardiologistas responderam que n?o, 25,5% dos MOE tamb?m disseram n?o encaminhar e apenas 1 CDOE respondeu n?o tratar nem encaminhar. Todos os periodontistas disseram tratar os pacientes com doen?as periodontais quando identificadas. Os m?dicos parecem n?o creditar import?ncia na rela??o que existe entre a doen?a periodontal e a cardiovascular e os CDs mostraram um bom conhecimento sobre a rela??o. Talvez, se m?dicos e CDs trabalharem juntos, a incid?ncia da doen?a cardiovascular decres?a

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

Among the 29 cases of ameloblastoma, 24 were type solid and 6 unicystic. In 7 mandibular specimens of human fetuses found dental germs from the stage of bud to the crown. We note that the pattern of expression in the dental germs was variable for claudinas studied according to the cell type and stage of differentiation and was invariate only in the cells of stellate reticulum. In epithelium internal of enamel organ, claudin-1 has been decreasing with the progression of differentiation as to claudina-7 that was found in the cells of the peripheral papilla. For ameloblastoma the expression was more significant than that observed in dental germs. Fisher s exact test no found association between the expression of claudinas cells in central and peripheral and the type of ameloblastoma (solid or unicystic). Thus, in general the claudin-1 was positive in the central cell of 93,1% of the cases and in peripheral cells of 51,7%. The claudin-7 was expressed in the cells of all cases central and peripheral cells from 89,7%. For both claudins the distribution was predominantly diffuse cells both in central and peripheral cells. Given our findings it is suggested that the expression of claudins may be indicative of the involvement of these molecules in morphogenetics events culminating with the dental development and that possibly influence the development of neoplastic ameloblastoma / Investigamos a express?o imuno-histoqu?mica das claudinas -1 e -7 em ameloblastomas e germes dentais humanos, avaliando o padr?o de distribui??o (focal, regional ou difuso), as c?lulas que as expressavam (central ou perif?rica) e a localiza??o dessa express?o nos constituintes celulares considerando membrana, citoplasma e n?cleo. Dentre os 29 casos de ameloblastomas, 23 eram do tipo s?lido e 6 unic?sticos. Nos 7 esp?cimes mandibulares de fetos humanos observamos germes dentais desde a fase de capuz at? a fase de coroa. Constatamos que o padr?o de express?o nos germes dentais foi vari?vel para as claudinas estudadas de acordo com o tipo celular e est?gio de diferencia??o assemelhando-se apenas nas c?lulas do ret?culo estrelado. No epit?lio interno a express?o da claudina-1 foi decrescente com a progress?o da diferencia??o enquanto para a claudina-7 foi verificada nas c?lulas perif?ricas da papila. Para os ameloblastomas, de forma geral, a express?o foi mais significativa do que aquela observada nos germes dentais. Foi aplicado o teste estat?stico de Fisher o qual n?o demonstrou associa??o entre a express?o das claudinas nas c?lulas centrais e perif?ricas e o tipo do ameloblastoma (s?lido ou unic?stico). De uma maneira geral, a claudina-1 foi positiva nas c?lulas centrais de 93,1% dos casos e nas c?lulas perif?ricas de 51,7%. A claudina-7 esteve expressa nas c?lulas centrais de todos os casos e nas c?lulas perif?ricas de 89,7%. Para ambas as claudinas a distribui??o foi predominantemente difusa tanto nas c?lulas centrais como nas c?lulas perif?ricas. Diante dos nossos achados sugere-se que a express?o das claudinas pode ser indicativa da participa??o destas mol?culas nos eventos morfogen?ticos que culminam com a forma??o dental e possivelmente influenciam o desenvolvimento neopl?sico dos ameloblastomas

The aim of this study was to verify the behavior of five brands of NiCr alloys, indicated to porcelain fused to metal restorations, comparing the castability with the ability of reproducing the thin edges of restoration margins. The samples were divided in five groups, each one for one brand, with ten repetitions for castability test and ten for edge reproduction, in a total of 100 specimens. A carbon free phosphate bonded investment was used for all casting procedures. Optical microscopy was used to investigate the microstructure of the specimens obtained with two of the alloys, those which have shown better results. Statistical analysis stated that the commercial brand Tilite showed both better castability and edge reproduction. / O objetivo desta pesquisa foi verificar o desempenho de cinco ligas de níquel-cromo para restaurações de metalocerâmicas, comparando a fluidez com a capacidade de cópia da borda fina das restaurações. Os corpos-de-prova foram divididos em 5 grupos um para cada liga, sendo realizado dez corpos-de-prova para o teste de fluidez e dez corpos-de-prova para o teste da cópia da borda, totalizando 100 corpos-de-prova. Um revestimento de fosfato sem carbono foi usado para todas as inclusões e fundições. Em seguida foram submetidos a microscopia óptica, para se observar a microestrutura das duas ligas que obtiveram os melhores desempenhos. Os resultados, após análise estatística, demonstraram que a liga Tilite apresentou a melhor fluidez e melhor cópia da borda.

As condições analisadas foram: cárie dentária, doença periodontal, uso e necessidade de prótese dentária e lesões de mucosa. A amostra foi composta de 268 diabéticos e 270 indivíduos não diabéticos compondo o grupo controle. Para a coleta dos dados, foram utilizados os índices recomendados pela Organização Mundial de Saúde. Os exames foram realizados nos domicílios dos indivíduos selecionados por examinadores previamente calibrados. Os dados foram processados no Programa de computação Epi info versão 3.3.2 para o Sistema Operacional Windows e estatisticamente analisados. Os resultados demonstraram que: não houve diferença na prevalência de cárie. O CPOD foi igual a 25,7 e 25,4 para diabéticos e grupo controle, respectivamente, com uma grande perda dentária para ambos os grupos. A presença de cálculo foi verificada em 10,6% dos diabéticos e em 13,6% do grupo controle com a prevalência de bolsa periodontal mais evidente em diabéticos (p<0,05). Aproximadamente metade da amostra necessitava de prótese superior e cerca de 78% dos examinados necessitavam de prótese inferior, não diferindo entre os grupos (p > 0,05). A ocorrência de lesões de mucosa bucal, como estomatites e lesões hiperplásicas, em ambos os grupos, foi relacionada ao uso de prótese dentária inadequada. Os dados encontrados demonstram prevalência significante em todas as condições estudadas em ambos os grupos, mas só a doença periodontal teve relação estatisticamente significante com a condição de Diabetes Mellitus. / This study assessed the oral health of attended diabetics by Family Health Care Service in the city of Belém, state of Pará, Brazil. The oral diseases analyzed were: dental caries, periodontal disease, use and necessity of dental prosthesis and oral lesion. The sample was composed of 268 diabetic patients and 270 not diabetic patients composing the control group. The indexes recommended for the World Health Organization were used. The examinations had been carried through in the home of the patients by examiners previously calibrated. The data were processed and analyzed in the software Epi info, 3.3.2 version for Windows. The results demonstrated that did not have difference in the prevalence of caries. The DMF index was 25.7 and 25.4 for diabetic and control group, respectively, with a great dental loss for both. The more prevalent periodontal condition was the presence of calculus in 10.6% of the diabetic and 13.6% for the control group, and the predominance of periodontal pockets was more obvious in diabetic (p<0.05). Approximately half of the sample needed superior dental prosthesis and almost 78% needed inferior dental prosthesis, not differing between the groups (p>0.05). The occurrence of lesions in oral mucosa in both the groups was related to the inadequate use of dental prosthesis as stomatitis and denture hyperplasia. The data demonstrated to high prevalence of all the conditions studied in both the groups, but only the periodontal disease had significant relation with the condition of Diabetes Mellitus.

Avaliou-se a capacidade antimicrobiana in vitro de diferentes solu??es a base de hidr?xido de c?lcio e tergentol partindo em princ?pio do HCT 20, solu??o irrigadora dos canais radiculares composta por 80% da solu??o saturada de hidr?xido de c?lcio (?gua de cal) e 20% do detergente tergentol buscando verificar sua poss?vel indica??o como solu??o para bochechos, visando preven??o ou combate a doen?as como c?rie dent?ria e doen?a periodontal. No laborat?rio de microbiologia do Departamento de Odontologia da UFRN, foram realizados testes em discos de antibiograma para os microrganismos: Streptococcus mutans, Streptococcus sanguis, Streptococcus sobrinus e Lactobacillus casei. Bem como em bact?rias formadoras de biofilme para os mesmos, ? exce??o do L. casei. Estipulou-se diferentes concentra??es de tergentol para a ?gua de cal, al?m do tergentol em ?gua destilada, usou-se digluconato de clorexidina a 0,12% como controle positivo e ?gua destilada como controle negativo. Os resultados mostraram desempenho inferior das solu??es a base de Ca(OH)2 em rela??o ? clorexidina frente a estes microrganismos e ? metodologia empregada, direcionando pois, para a n?o indica??o do uso do HCT 20 como colut?rio bucal

For that, a total of 68 healthy students between 11 and 13 years old, not allergic to crustacean and not users of antibiotics or antimicrobial agent for the last three months or during the treatment, was selected. From those, thirty two individuaIs used the mouthrinse test, and thirty six, the control one. The participants rinsed 10 mL of the solutions twice a day, one during the moming (which was supervised), and another one during the aftemoon (which was not supervised), for fifteen days. The saliva collect for the microbiological analysis, as well as the perceptible bacterial film and gingival bleeding indices check, were made before the use ofthe mouthrinses (base line), immediately after the last mouthrinse on the day (zero time) and fifteen days after (fifteen time). These data were collected at school and the saliva was carried inside the ice to the laboratory. The samples were diluted, and 0.1 mL ofthe 10 -1 dilution was seeded in Rogosa SL agar, for further analysis of the total of lactobaci/lus~ 0.1 mL of the 10-4 dilution in Mitis Salivarius with bacitracin, for S. mutans analysis; and 0.1 mL of the 10-6 dilution in Mitis Salivarius for the analysis ofthe total of streptococcus. The Rogosa SL agar plates were incubated in aerobic at 37?C for 72 hours and the MSB and the MS were incubated in anaerobic in Gaspak@ jars at 37?C for 48 hours for further count ofColonies Former Units (CFUs). The assay was made in duplicate for each bacterial group analyzed. The number of CFUs transformed in LOGlO was analyzed according to the following tests: ANOV A, t of Paired and Not Paired Student, Friedman, Man-Whitney and square-qui test. On the base line, alI the variables analyzed were similar on both tested groups. On both groups, for the total of streptococcus there was no significant difference along the time and for S. mutans there was a statistic significant increase of the CFUs from the base line to the zero time. For the total of lactobaccilus there was no significant difference on the test group along the time, and on the control there was a significant increase ofthe CFUs ITom the base line to the zero time. For both groups, there was significant decrease ofthe perceptible bacterial film index along the time, and that can be explained by the mechanic effect of the mouthrinse over the bacterial film and by the participation of the students on the research which could have motivated him to a better toothbrushing (Hawthome effect). The gingival bleeding index also showed a decrease along the time, even though it was not significant. Therefore, the conclusion of this study was that the chitosan at 0.4 % mouthrinse was not effective on the CFUs reduction of the three bacterial groups analyzed, as well as on the reduction of the perceptible bacterial film and gingival bleeding indices / O objetivo deste estudo foi avaliar a efic?cia do bochecho de quitosana a 0,4% com alto peso molecular e alto grau de desacetiliza??o sobre a redu??o do total de estreptococcus, Streptococcus mutans, total de lactobacilos e sobre os ?ndices de placa vis?vel e sangramento gengival. Para tanto, foram selecionados 68 estudantes saud?veis, com idade entre 11 e 13 anos, n?o al?rgicos a crust?ceos e que n?o tivessem usado antibi?tico ou antimicrobiano nos ?ltimos tr?s meses ou durante o tratamento. Trinta e dois indiv?duos utilizaram o bochecho teste e trinta e seis o controle. Os participantes bochecho 10 ML das solu??es duas vezes ao dia, um pela manh? (supervisionado) e outro ? tarde (n?o supervisionado, durante quinza dias. A coleta de saliva para an?lise microbiol?gica, bem como a aferi??o dos ?ndices de placa vis?vel e de sangramento gengival, deu-se antes do uso dos bochechos (linha base),no dia imediatamento ap?s o ?ltimo bochecho (tempo zero) e quinze dias ap?s (tempo quinze). Esses dados foram coletados na escola e a saliva transportada em gelo at? o laborat?rio. As amostras de saliva foram diluidas e 0,1ML da dilui??o 10 elevado a menos 1 foi semeada em Rogosa SL ?gar para a posterior an?lise do total de lactobacilos; 0,1mL da dilui??o 10 elevado a menos 4 em Mitis Salivarus com bacitracina, para an?lise de S mutans, e 0,1mL da dilui??o 10 elevado a menos 6 em Mitis Salivarius para an?lise do total de estreptococous. As placas de Rogosa SL ?gar foram incubadas em aerobiose a 37 grau cent?grado por 72 horas e as de MSB e MS foram incubadas em anaeribiose em jarras Gaspak a 337 grau cent?grado, por 48 horas, para posterior contagem das unidades formadoras de col?nias (UFCs). O ensaio foi feito em duplicadta para cada grupo bacteriano analisado. O n?mero de UFCs transformados em LOG10 foi analisado mediante os seguintes testes: ANOVA, t de Student emparelhado e n?o emparelhado, Friedman, Man-Whitney e teste do qui-quadrado. Na linha base, todas as vari?veis analisadas no estudo foram semelhantes nos dois grupos testados. Em ambos os grupos, para o total de estreptococcus n?o houve diferen?a significativa ao longo do tempo; para o S. mutans, houve aumento estatisticamente significativo das UFCs da linha base para o T0. Para o total de lactobacilos, n?o houve diferen?a no grupo teste ao longo do tempo e, no controle, houve aumento significativo das UFCs da linha base para o T0. Em ambos os grupos, houve diminui??o significativa do IPV ao longo do tempo. O ISG tamb?m apresentou redu??o ao longo do tempo, por?m n?o foi significativa. Portanto, este estudo concluiu que o bochecho de quitosana a 0,4% n?o foi eficaz na redu??o das UFCs dos tr?s grupos bacterianos analisados, assim como, na redu??o do IPV e ISG

This research aims to determine a protocol for the mechanical control of the dental biofilm performed by the professional. A protocol that was able to maintain the periodontal health of the patients under orthodontic treatment with fixed appliances, and in order to do so, it used a non-controlled, randomized and blind clinical essay. The sample involved 40 adolescents who were under the installation of fixed orthodontics appliances and it was divided in three groups, as follows: monthly controlled group (group 1) composed of 11 patients, the quarterly controlled group (group 2) with 16 patients and the semestrial controlled group (group 3) with 13 patients. For data collection, an interview and clinical exams with probing depth measurement, quantity of keratinized mucosa, Gingival Index and the Plaque Index were used. On the initial exam all patients received brushing guidelines as well as the professional control of dental biofilm, with periodontal scaler, Robinson s brush and prophylactic paste. However, Group 1 returned every month for control procedures; Group 2 every three months and Group 3 after six months. The intervention had a six-month duration (for all the three groups), when all the exams were repeated by another examiner who did not know which group each patient was inserted in. Finally, the research concluded that despite the fact there is no statistically significant difference among the three groups, clinically the patients from the monthly group presented a better response to professional control, with less accumulation of dental biofilm and less rate of gingival inflammation. Thus, the mechanical control of the dental biofilm performed by the professional could not avoid gingival increase, characterized by the raise of probing depth measurement, neither the quantity of keratinized mucosa / A presen?a do aparelho ortod?ntico fixo dificulta a higieniza??o, tornando comum o aparecimento de problemas periodontais nestes pacientes, apesar de manterem contato todo m?s com o dentista. O objetivo desta pesquisa foi determinar um protocolo, de controle mec?nico do biofilme dent?rio executado pelo profissional, que fosse capaz de manter a sa?de periodontal de pacientes em tratamento ortod?ntico com aparelho fixo, para tanto se empregou um ensaio cl?nico, n?o-controlado, randomizado e cego. A amostra envolveu 40 adolescentes na fase de instala??o do aparelho ortod?ntico fixo, e foi dividida em tr?s grupos sendo eles: o grupo do controle mensal (grupo 1) composto de 11 pacientes, o grupo do controle trimestral (grupo 2) com 16 pacientes e o grupo do controle semestral (grupo 3) com 13 pacientes. Para a coleta de dados adotou-se uma entrevista e exame cl?nico com medi??es da profundidade de sondagem, quantidade de mucosa ceratinizada, ?ndice Gengival e o ?ndice de Placa. No exame inicial todos os pacientes receberam orienta??o de escova??o e controle profissional de biofilme dent?rio, com curetas periodontais, escova de Robinson e pasta profil?tica. Sendo que o grupo 1 retornou a cada m?s para o controle; o 2 a cada tr?s meses e o 3 ap?s seis meses. A interven??o teve uma dura??o de seis meses (para os tr?s grupos), quando todos os exames foram repetidos por outro examinador que desconhecia a qual grupo pertencia cada paciente. Ao final da pesquisa foi poss?vel concluir que apesar de n?o existir diferen?a estatisticamente significativa entre os tr?s grupos, clinicamente os pacientes do grupo mensal apresentaram uma melhor resposta ao controle profissional, com menor ac?mulo de biofilme dent?rio e menor grau de inflama??o gengival. Contudo, o controle mec?nico do biofilme dent?rio executado pelo profissional n?o conseguiu prevenir o aumento gengival, caracterizado pela eleva??o da profundidade de sondagem, bem como da quantidade de mucosa ceratinizada
