MÉTODOS: o desenho do estudo foi do tipo transversal caracterizado por um censo, sendo examinadas 432 crianças de cinco e seis anos, de ambos os sexos, das escolas da rede municipal de Passo Fundo, Rio Grande do Sul. O levantamento epidemiológico foi realizado por meio de exames clínicos e dados relativos às questões demográficas referentes aos pré-escolares, segundo metodologia proposta pela Organização Mundial da Saúde. Os examinadores foram devidamente treinados e calibrados, obtendo resultado do teste Kappa de 0,91. A pesquisa foi encaminhada e aprovada pelo Comitê de Ética em Pesquisa do Instituto de Cardiologia de Porto Alegre-RS. RESULTADOS: o índice ceo-d foi de 4,1 (±3,73) e somente 106 (24,5%) das crianças estavam livres de cárie dentária na dentição decídua; a prevalência da necessidade de ...

A população estudada foi constituída por 633 escolares, de ambos os sexos, matriculados em vinte e seis escolas municipais de ensino fundamental, nas idades índices citadas. Os exames foram realizados por três examinadores previamente calibrados para a aplicação do Índice de Dean. A prevalência de fluorose dentária no grupo estudado foi de 32,8%. O grau predominante foi o muito leve (78,4%), seguido pelos graus leve (11,1%), questionável (8,7%) e moderado (1,9%). A prevalência de fluorose dentária na população estudada foi expressiva, embora com um baixo grau de severidade. Os fatores idade e índice de cárie dentária mostraram-se relacionados à variável resposta.

Ten public health centres and ten centres associated with health insurance companies were randomly selected. The size of the sample was calculated using a standard error of 2.5%. A confidence interval of 95% and a 50% prevalence of reasons for extractions were used for calculating the sample. The minimum size of the sample for meeting these requirements was 381 patients. Patients were randomly selected from the list of adults registered at each centre. A total of 410 patients were invited to take part in the study. The response rate was 100%, but 6 patients were excluded due to incompleteness of data in the questionnaire applied. An assessment was made to obtain the number of decayed, missing or filled ...

MATERIALS AND METHODS: The sample comprised 50 patients aged 16 to 52 years, of both genders, which were divided into 2 groups with 25 patients each. Group I underwent biomechanical preparation by the step-back technique, and Group II was treated by the rotary technique with nickel-titanium instruments (K3). Patients were submitted to antisepsis of the oral cavity with chlorhexidine digluconate and three samples of blood were collected for blood culture: preoperatively, immediately after the biomechanical preparation and 10 minutes later. The significance level adopted was 5.0%, and analysis was performed by descriptive and inferential statistics by means of the Fisher's exact test, Fisher-Freeman-Halton test and Student's t test. Data were analyzed on the ...

Objective: The purpose of this study was to investigate the teaching of geriatric dentistry in Brazilian universities. Materials and methods: This study consisted of questionaires regarding the training in geriatric dentistry in 104 dental schools included in the National Institute of Education Research (INEP) in 2001. In order to calculate the sample (a random stratified one), the confidence interval was set at 99% and a maximum permitted error of 3% was adopted. Pearson's chi-square test was used in the inferential analysis. Results: From the 64 dental courses which were studied, only 25 included geriatric dentistry in the curriculum. From 1857 students who were involved in the study, 41% sought knowledge outside the dental school and 98% considered that it was important that this subject should be included in the curriculum. There was statistical significance between geriatric dentistry teaching and the students' preference as well as the prospect of working with this group of the population. Geriatric dentistry as an individual subject was absent from the curriculum in two-thirds of the dental courses investigated. Knowledge was often transmitted as part of dental prosthetics and most of the students stated that they would want to be able to treat elderly people. It was relevant to note that senior students expected to work in this field. Conclusion: Dental students in Brazil do not have adequate training in geriatric dentistry.

The dental records of the sampling comprised all patients treated in 1998 and 1999. Trials were standardized and a pilot study was carried out to determine the feasibility of the proposed study. Chi-square and Fisher's exact tests were used to calculate the level of significance that was set at 5%. Logistic regression models were used to confirm significant effect of some variables on the endodontic outcome. The final sample size comprised 311 (75.9%) women and 99 (21.1%) men. The majority of cases (82.9%) were considered successful. Success was less frequent for patients with up to primary school education (55.6%) than for those with a higher degree of education (89.7%). The vital condition of the pulp showed a statistically significant relationship with the success of endodontic therapy (p<0.05). ...
