Aim: The aim of this present study was to assess the dental caries prevalence in children and adolescents aged 3-19 in the Nordic countries, and to examine if the caries prevalence is affected by socioeconomic and cultural differences. Method: The study is a literature review based on 20 scientific medical reports based on the aim of this study. Result: Decayed missed filled surfaces (dmfs) of the 3-year-olds varies from 0.3 to 0.99 and from 0.9 to 7.3 in 5-year-old children. The Nordic 12-year-olds have similar numerical values. In Nordic 14-year-olds caries prevalence increases. In the late teens there is a reduction in caries prevalence. Children at Greenland have five times more teeth decayed than other Danish children. Socioeconomic and cultural differences can affect the caries prevalence negatively. Conclusions: The caries prevalence in 3-19-year-olds in the Nordic countries, exceptGreenland, does not differ significantly between the countries. It is difficult to determine if the caries prevalence generally has decreased or increased in the Nordic countries. A higher caries prevalence can be seen in children with an immigrant background.

Tandvården har goda möjligheter att få kännedom om patienters tobaksvanor eftersom flertalet människor besöker tandvården regelbundet. Det finns därför goda möjligheter att utföra tobaksavvänjning med de som röker eller snusar. Syftet med litteraturstudien var att belysa metoder som finns för tobaksavvänjning och vilka resultat dessa metoder ger. Sökningen gjordes i databasen Pubmed och begränsades till artiklar som är publicerade under de senaste tio åren och till studier som har utförts inom tandvården. Litteraturstudien inkluderade åtta studier. Resultatet visade att det finns flera olika kombinationsmetoder som används för tobaksavvänjning. I tre artiklar har 5A metoden använts i kombination med nikotinersättningsmedel. I övriga artiklar användes fem olika kombinationsmetoder med olika uppföljningstider. I en av kombinationsmetoderna beskrevs två metoder. Utöver dessa metoder fanns en metod för snusavvänjning. Resultatet visade skillnader i lyckandefrekvens med upphörande av tobaksvanor. Tolv månaders avvänjning och uppföljning i två av kombinationsmetoderna samt metoden för snusavvänjning gav högst lyckandefrekvens (36 %, 25 % och 30 %). Lägst lyckandefrekvens var 7 % efter tolv månaders uppföljning i en av 5A metoderna. Studiens slutsats är att det finns få publicerade studier om tobaksavvänjning inom tandvården som är baserade på utvärdering av tobaksavvänjningsmetoder som är utförda på patienter. Uppföljning och rådgivning samt stöttning har betydelse för resultatet. / Patients with tobacco habits visit the dental care regularly, therefore it is well placed to carry out tobacco cessation for those who smoke or use snuff. The purpose of this study was to highlight methods available for tobacco cessation and results of these methods. The authors searched in the database PubMed and was limited to articles published during the last ten years and performed in the dental care. The framework was limited to eight studies which were performed in the dental care. The results showed that there are several different combination methods for tobacco cessation. In three articles, the 5A method was used in combination with nicotine replacement therapy. In other articles five different combination methods with different follow-up times were used. In one of those with combined approach two methods are described. In addition a method was used for snuff cessation. The result showed differences in frequency of success to tobacco stop. The best result was shown after twelve months tobacco cessation and a follow up in two of the combination methods and the method for snuff cessation (36%, 25% and 30%). The lowest success rate was 7% after twelve months follow up with one of the 5A methods. The conclusion of the study is that there are few published studies regarding tobacco cessation in the dental care, which are based on evaluation of methods performed among patients. Follow up, counselling and support have essential effects on the result.

The aim of the study was to investigate the knowledge, management and self-perception of oral health among stundents attending the University of Dar es Salaam, Tanzania. The study consisted of 273 students attending the teacher programme and a questionnaire was used to collect the data. The result showed that 153 (58%) of the participants stated that the purpose of using fluoride was prevention of caries. The majority answered that bacteria and sugar in relation to caries was significant. The dominant source of oral health training was school. Toothbrush was the dominant cleaning aid and the usage of fluoride toothpaste was fairly high among the students. One hundred and forty nine (55%) respondents stated that they were in need of dental treatment and ninety-two (34%) students felt that life in general was less satisfying due to oral heath problems. The conclusion of the study was that the students show rather good knowledge concerning oral disease and its prevention but gaps in knowledge concerning underlying factors. The management of oral health seemed to be good among the students. Although, a significant number of students stated that they were in need of dental treatment, felt that life was less satisfying due to oral problems and had oral problems interfering with daily life. / Syftet med studien var att undersöka kunskapen om, skötseln av och självuppfattningen om den orala hälsan bland studenter på University of Dar es Salaam, Tanzania. I studien ingick 273 studenter som studerade till lärare, en enkät användes för att samla in data. Resultatet visade att 153 (58%) av studenterna uppgav att syftet med fluor var att förebygga karies. Majoriteten svarade att bakteriers och sockers relation till bildandet av karies var betydelsefull. Studenterna uppgav att skolan var den största källan till träning i oral hälsa. Tandborste användes som främsta hjälpmedel för att rengöra tänderna och användning av fluortandkräm var ganska hög bland studenterna. Etthundrafyrtionio (55%) av deltagarna uppgav att de var i behov av tandvård och nittiotvå (34%) att den orala hälsan gav upphov till att livet i allmänhet var mindre tillfredställande. Studiens slutsats är att studenterna hade ganska god kunskap om sjukdomar i munhålan och dess prevention men det fanns kunskapsbrister kring bakomliggande faktorer. Skötseln av den oral hälsa tros vara god. Trots detta uppgav ganska många av de studerande att de hade behov av tandvård, hade känt att livet var mindre tillfredsställande på grund av problem i munhålan och hade orala problem som påverkade det dagliga livet.

The objectives of the study: 1) to describe the malocclusion prevalence among Lithuanian schoolchildren in 10–11 and 14–15-year old age groups; 2) to evaluate the need for orthodontic treatment among 10–11, 14–15 year-old schoolchildren in Lithuania using the ICON index; 3) to investigate the association between normative (objective) and self-perceived (subjective) orthodontic treatment need; 4) to assess the associations of age, gender, and socioeconomic factors with dental appearance satisfaction and demand for orthodontic treatment. The survey was conducted in 41 randomly selected schools in 10 counties of Lithuania. The study recorded crowding, spacing, overbite, crossbite, relationship of the first upper and lower molars according to Angle’s classification, the orthodontic treatment need was assessed using the ICON index and the children were also invited to complete a questionnaire about treatment need and their appearance. The results showed that 77% of 10–11-year-old and 61.7% of 14–15-year-old schoolchildren had malocclusion. The treatment need among younger schoolchildren was higher than in older group. The subjective demand for orthodontic treatment among 10–11-year-old schoolchildren and 14–15-year-old schoolchildren was similar.

The objective of the study is to investigate the total antioxidative capacity of plasma and the level of survival of non-activated neutrophilic leucocytes in peripheral venous blood, their oxidative function and its changes when activated by non-opsonised E.coli and S.aureus, exposed to glucose and investigate the effect of glycosylated haemoglobin (HbA1c%) of different concentrations, using the methods of luminol- and liucigenin-dependent chemiluminescence, with respect to the patients suffering from type 1 diabetes mellitus (DM) and a severe form of periodontitis, as well as those who suffer from type 1 diabetes mellitus, but have healthy periodontal tissues, and also persons without systemic diseases and inflammatory periodontal diseases. An integrated investigation of the level of oxidative capacity of neutrophilic leucocytes in peripheral venous blood, using the methods of luminol- and liucigenin-dependent chemiluminescence, of the patients who suffer from type 1 diabetes mellitus and a severe form of periodontitis as well as persons suffering from type 1 diabetes mellitus, but with no inflammatory periodontal disease, and also healthy persons, has been performed for the first time. A new presumption has been presented on the basis of the collected material, which states that the development of inflammatory diseases of periodontal tissues is determined by the decreased level of survival of bactericidal myeloperoxidase system of neutrophilic leucocytes.

Magister Chirurgiae Dentium - MChD (Maxillo-Facial & Oral Surgery) / South African dentists have a legal and ethical obligation to maintain complete and comprehensive dental records. In addition to the legal and ethical requirements, dental records are also important in the case of medico-legal issues, quality assurance processes and forensic purposes. Valuable forensic evidence contained in dental records are used in the identification of victims of mass disasters, personal victim identification e.g. in severely decomposed or skeletonized remains where DNA or other biometric data are not available. The victim identification process is highly dependent on complete, legible and accurate dental records. A review of the literature however shows that dental record keeping practices are sub-optimal worldwide. There is a paucity of studies in South Africa regards to dental record keeping practices. The aim of this study was to assess the record keeping practices of a sample of private practicing dentists in Cape Town and surrounding towns, for forensic dental purposes. Knowledge and awareness regards to forensic odontology as well as adherence to the guidelines prescribed by the Health Professional Council of South Africa were also assessed. This was a cross-sectional descriptive study, employing a researcher-administered questionnaire and a dental checklist for forensic valuable items in the dental file. The results were entered in a MS Excel spreadsheet and statistically analysed using IMB SPSS Statistics. This study concluded that most of the dental records kept by Cape Town dentists are near to optimal and would be helpful during forensic odontology investigations. However, shortcomings in record keeping practices exists which may compromise the forensic accuracy of their dental records. The study also shows a significant difference in dental record keeping practices by dentists practicing in lower income areas in Cape Town, compared to those practicing in economic affluent areas. The dentists in this study adhered to most of the guidelines prescribed by the Health Professional Council of South Africa however, important medico-legal information was missing from most dental records. This study hopes to contribute to future comprehensive studies in the broader South Africa to determine the validity of dental records for forensic odontology purposes.

Orientador: Cintia Lúcia Maniscalco / Banca: Paola Castro Moraes / Banca: Joaquim Coutinho Netto / Resumo: A fístula oronasal é uma comunicação anormal entre a cavidade oral e nasal. É ocasionada normalmente por doença periodontal avançada, onde o vértice alveolar, principalmente do canino superior, sofre processo de degeneração resultando na injúria; também pode ser causada por traumas, corpos estranhos, extrações dentárias inadequadas, cirurgias na cavidade oral, choques elétricos e atropelamentos. Nos cães, as fístulas acarretam vários sinais clínicos como espirros, secreção nasal, sinusites, rinites, infecções no trato respiratório e até pneumonias aspirativas. Devido à periodontites crônicas e o pouco tecido circunjacente, são de difícil reparação, sendo o pós-operatório problemático pela ocorrência de deiscência de sutura e recidiva com concomitante processo inflamatório e infecção. O látex da seringueira (Hevea brasilienses) mostrou em vários outros experimentos seu poder angiogênico e cicatrizante na formação tecidual. Este experimento teve por finalidade utilizar fração proteica purificada do látex de seringueira no reparo de comunicações oronasais provocadas, para simulação experimental de fístula, após exodontia de caninos superiores de cães. Foram obtidos como resultados uma melhor qualidade na cicatrização, menor processo inflamatório ao final de 21 dias, menor ocorrência de deiscência de sutura e maior quantidade de tecido ósseo no alvéolo, concluindo-se que a utilização do fator proteico auxilia no processo de reparo, tornando-o mais rápido e eficiente / Abstract: The oronasal fistula is an abnormal communication between oral and nasal cavities. It is generally caused by advanced periodontal disease, where the alveolar vertex, especially from the superior canine tooth, become degenerated resulting in that injury; it can either be caused by trauma, foreign bodies, inappropriate dental extractions, surgeries in the oral cavity, electric shock and car run over. In dogs, fistulas may cause several clinical signs as sneeze, nasal secretion, sinusitis, rhinitis, respiratory tract infection and even aspiration pneumonia. Because of chronic periodontitis and little tissue surrounding the fistulas, they are hard to repair; with difficult post-operative period due to the occurrence of suture dehiscence and fistulae recurrence with concomitant inflammatory process and infections. In others several experiments the rubber tree latex (Hevea brasiliensis) showed its angiogenic and healing power in tissue growth formation. The purpose of this experiment was to use a purified protein fraction from rubber tree latex to repair an oronasal communication induced for experimental simulation of the fistula, after extraction of superior canines in dogs. The obtained results corresponded to better healing quality, less inflammatory process after 21 days, less suture dehiscence and more alveolar bone tissue, concluding that the utilization of the protein factor helps in the repair process, making it faster and efficient / Mestre

In this purpose, a sectional study of infantiles aging 5, 8 and 12 years old was carried out. The average prevalance of malocclusions in the group as a whole was 76,5%. Considering the different dentitions separately, the study showed malocclusion prevalence as follows: Deciduous Dentition 75,5%; Mixed Dentition 84% and Permanent Dentition 70,5%. The most common malocclusion cases found in the deciduous dentition were openbite (20.6%); overbite (16.6%) and maxillary overjet (14,7). Mixed Dentition: the most commonly found occlusional malfunctions in this dentitional phase were maxillary overjet (33,8%); crowding (28,3%), and mandillary discrepancy (19,9%). In the univaried analysis, he application of the Chi square test of independence, (significance 5%), has indicated a meaningful association of the variables social class (p=0,019), primata space (p = 0,036), habits (p= 0,002) and time-and-habit (P=0,03). The same test on the permanent dentition group revealed a significant association for the independent variables, as follows: Social class (p=O,OOO), School (p=O,OOI), Income (p=O,OOO), housing standard (p=0,001), facial pattem (p=0,004), caries record (p=0,031). No significant association was found in the mixed dentition. The Logistic Regression analysis on the deciduous dentition has shown that income, ethnicity, habit and canine relationship constitute factors of risk regardless of the other variables. As for the permanent dentition, only Facial Pattem was pointed as a factor of risk for the formation of malocclusion / O prop?sito deste estudo foi verificar a preval?ncia de oclusopatias, bem como dos seus determinantes nas denti??es dec?dua, mista e permanente na cidade de Natal/RN. Para tanto, foi realizado um estudo seccional com crian?as de 5, 8 e 12 anos (n=765). A preval?ncia geral de oclusopatias, observando-se as tr?s denti??es, foi de 76,5%. No que se refere ? preval?ncia para cada denti??o obteve-se 75,5% para a denti??o dec?dua, 84,8% e 70,5% para as denti??es mista e permanente, respectivamente. As principais oclusopatias encontrada na denti??o dec?dua foram a mordida aberta anterior (20,6%), seguida da mordida profunda (16,6%) e sobressali?ncia positiva (14,7%). Em rela??o ? denti??o mista, os problemas oclusais encontrados foram a sobressali?ncia positiva (33,8%), apinhamento (28,3%) e discrep?ncia maxilar (20,7%). Essa predomin?ncia permanece inalterada na denti??o permanente e, dessa forma, teve-se: sobressali?ncia positiva (27,4%), apinhamento (22,8%) e discrep?ncia maxilar (19,9%). Na an?lise univariada, atrav?s do teste Qui-quadrado (n?vel de signific?ncia de 5%), verificou-se associa??o significativa em rela??o ? presen?a de oclusopatias na denti??o dec?dua, para os fatores de risco: classe econ?mica (p=0,019), espa?o primata (p=0,036), rela??o dos caninos (p=0,000), h?bitos (p=0,002) e tempo e h?bito ?p=0,03). Para a denti??o permanente, associa??o significativa com a presen?a de oclusopatias, foi encontrada para classe econ?mica (p=0,000), escola (p=0,001), renda (=p0,000), tipo de moradia (p=0,001), padr?o facial (p=0,004) e experi?ncia de c?rie (p=0,031). N?o houve associa??o signifiacativa entre nenhum fatores de risco, e a presen?a de oclusopatias na denti??o mista. Na an?lise de regress?o log?sitica, para a denti??o dec?dua, observou-se que, renda, etnia, h?bito e rela??o dos caninos constitu?ram fator de risco, independente das outras vari?veis estudadas. Na denti??o permanente, apenas o padr?o facial (P= 0,025), foi fator de risco para o desenvolvimento de oclusopatias. Os achados desse estudo revelaram que, tanto a preval?ncia quanto a necessidade de tratamento apresentaram percentuais elevados e, portanto faz-se necess?rio a cria??o de estrat?gias para minimizar esse problema, bem como evitar exposi??es aos fatores de risco de interven??o, tais como, baixa renda e h?bitos e aos moduladores dos fatores de risco heredit?rios: etnia, rela??o dos caninos e pad?o facial
