Introduction: Dental caries is a large problem affecting all population. In Brazil, caries prevalence has decreased over the last years, but it is still a public health issue requiring frequent ...evaluation and care by dentists. Objective: To evaluate the oral health conditions of schoolers aged 5-12 years relating them with socioeconomic and demographic determinants. Material and methods: The children were examined by a previously calibrated examiner to obtain DMF and dmf scores. The parents answered a questionnaire regarding to the socioeconomic condition. Prior to the examinations, the parents signed a free and clarified consent form and only their children were evaluated. The results were analyzed descriptively and by Chi-square test, at significance level of p<0.05. Results: The sample (n=111) showed a mean age of 7±1.7 years (mean ± standard deviation), composed of 58 boys and 58 girls. 66.6% of the sample exhibited dmf values = 0, while 102 schoolers had DMF values = 0. With regard to the parents' education level, 78.37% of the mothers had more than 9 years of education and 43.34% of the fathers had 9 to 11 years of study. Concerning to family income, 36.93% of the families presented mean income of 1-3 minimum wages (R$ 788.00 to R$ 2,364.00). No statistically significant differences (p≤0.05) were seen between caries rates vs. parents' education and caries rates vs. family income. Conclusion: 5-12 year schoolers showed low dmf and DMF values, suggesting that parents' education and income might have influenced on the results. Further studies are necessary to understand/assess the predisposing factors to dental caries development.
Tooth decay is one of the most common chronic oral diseases found in industrial countries and is a multifactorial disease which has sugar as a key dietary factor. The amount of saliva concentration ...and presence of cariogenic bacteria will favor the development of caries. Because of this, the aim of this study was to collect and analyze data on oral alterations referred to tooth decay, oral pH changes, and changes of the oral microbiota in two distinct groups of workers. Material and methods: 30 individuals belonging to two different groups of workers: group A (GA) – workers who maintain daily contact with the confectionery; group B (GB) – workers who do not have such contact. Saliva collection was done by analysis of the salivary pH in both groups, as well as cultivation of Lactobacillus spp and S. mutans. We also evaluate the dental status of individuals belonging to the two groups through the DMFT index. Results: After the examinations of 30 workers (17 from the GA 9 men and 8 women and 13 in the GB 7 men and 6 women), the mean DMFT of the individuals in the group A and group B, was 7.41 (SD 5.14) 7.08 (SD 5.56), respectively, without statistically significant differences (p < 0.05). The count of S. mutans and Lactobacillus spp, was not statistically significant. Conclusion: There was no statistically significant relationship between presence of dental caries and the fact that workers are in contact with sugar because they work on candy food industry, but new studies are needed for more precise research.
ABSTRACT Objective: The aim of the study was to evaluate performance of digital radiographic and two electronic apex locators, Propex II and Root ZX in root canal length determination in primary ...molars. Methods: 25 primary molars were divided into two groups, G1 without root resorption and G2 with root resorption. The exams were performed using all methods by two experienced examiners, with 1-week interval. The gold standard was determined by visual examination. The methods were statistically analyzed regarding the values of reproducibility and correlated with the gold standard by Pearson´s correlation coefficient. Results: The root canal length determination coincided with gold standard in 22.7% for Root ZX, 17.5% for Propex II and 12.5% for digital radiography. Correlation values were higher in G1, the Root ZX presented the highest values. In G2 the digital radiography showed the lowest correlation. In G1, the intra-examiner reproducibility values ranged from 0.925 to 0.523, and interexaminer 0.863 to 0.670. In G2, the values of intra-examiner reproducibility ranges from 0.864 to 0.097, and inter was 0.774 to 0.379. Conclusion: It was concluded that the methods performance varying according to examiner's experience. The Root ZX presented the highest reproducibility and accuracy.
RESUMO Objetivo: Avaliar o desempenho in vitro de radiografia digital e de dois localizadores apicais eletrônicos, Propex II e Root ZX na determinação do comprimento de canal em molares decíduos. Métodos: Foram selecionados 25 molares decíduos divididos em dois grupos, G1, sem reabsorção radicular e G2 com reabsorção radicular. Os exames foram realizados utilizando todos os métodos por dois examinadores experientes, com intervalo de 1 semana. O padrão ouro foi determinada por exame visual. Os métodos foram analisados estatisticamente em relação aos valores de reprodutibilidade e correlacionada com o padrão ouro pelo coeficiente de correlação de Pearson. Resultados: A determinação de comprimento de canal coincidiu com padrão-ouro em 22,7% para o Root ZX, 17,5% para Propex II e 12,5% para a radiografia digital. valores de correlação foram maiores no G1, o Root ZX apresentou os maiores valores. Em G2 da radiografia digital apresentou a menor correlação. No G1, os valores de reprodutibilidade intra-examinador variou 0,925-0,523 e interexaminadores 0,863-0,670. No G2, os valores da reprodutibilidade intra-examinador varia 0,864-0,097, e inter era 0,774-0,379. Conclusão: Concluiu-se que o desempenho dos métodos varia de acordo com a experiência do examinador. O Root ZX apresentou maior reprodutibilidade e precisão.

Introduction: The child abuse against children and teenagers is relevant and the dentist has a fundamental role in the process of identification of suspected cases. Objective: To evaluate the ...level of knowledge of the dentists about child/teenager abuse and the attitude towards identified cases, in the cities of Rio Negro (Paraná, Brazil) and Mafra (Santa Catarina, Brazil). Material and methods: Questionnaires were applied to 44 professionals of these cities, whopracticed in private and/or public health service. The questions covered the profile of respondents regarding gender, institution (public or private), level of education, practicing time and place. The information on abuse comprised the level of information about violence and knowledge on the compulsory notification of suspected cases. Results: Regarding the cases of abuse, 34% of the sampledealt with this situation. Almost half of respondents (47.7%) reported being able to recognize the typical lesions of child abuse, yet only 32% felt trained to do so. Only 22.7% reported having training to detect suspected cases. And 91% said they would notice the Guardian Council. About 48% confirmed they had knowledge of the legal implications in case of omission. Conclusion: Most of the dentists had insufficient knowledge about child abuse. However, the dentistsknow how to deal with such a situation. Continuing education seems to be an appropriate strategy to promote professional knowledge on the subject. It is also suggested the implementation of a national protocol to facilitate notifications and the classification of abuse types.
