Os objetivos deste trabalho foram conhecer a prevalência da cárie dentária e a necessidade de tratamento odontológico, além da distribuição da cárie dentária na população que apresenta índices de cárie mais elevados em escolares de doze anos. Foram examinados 309 adolescentes, de escolas públicas de Indaiatuba (SP), em 2004, selecionados mediante processo amostral aleatório sistemático e os exames seguiram os critérios da Organização Mundial de Saúde. O percentual de escolares livres de cárie foi de 38,8%. Dentre os escolares examinados, 36,6% (n=113) apresentaram atividade de cárie. O CPOD foi de 2,50 (IC95%=2,07-2,93). O componente cariado foi o mais prevalente (61,0%). O coeficiente de Gini foi 0,602 e o valor do índice SiC foi de 5,97 (IC95%=5,32-6,62); neste grupo em especial, 74,7% (n=74) apresentaram atividade de cárie no momento do exame. Desta forma, pode-se concluir que os escolares deste município apresentaram baixa experiência de cárie; entretanto, não apresentaram suas necessidades atendidas, uma vez que a maior parte do CPOD era formada do componente cariado, aos doze anos de idade. No grupo SiC, verificou-se que este apresentou-se bastante elevado, sendo recomendadas ações direcionadas a este grupo específico de adolescentes.

The objectives of this work was to know the dental caries prevalence and treatment need, besides the distribution of the dental caries in a population of 12 year-old teenagers with high incidence of dental caries. 309 adolescents of public schools of Indaiatuba, São Paulo State, in 2004, were examined. They were selected by process systematic random and the exams followed the World Health Organization criteria. The percentile of school caries free was of 38.8%. Among the adolescents examined, 36.6% (n=113) presented dental caries. DMFT was of 2.50 (IC95%=2.07-2.93). The decayed component was the highest (61.0%). The coefficient of Gini was 0.602 and SiC value was of 5.97 (IC95%=5.32-6.62); in this group especially, 74.7% (n=74) presented dental caries activity in the moment of the exam. Thus, it can be concluded that the adolescents of this city presented low dental caries experience; however, their needs were not assisted, once most of DMFT was formed of the decayed component at 12 years old. In the group SiC, it was verified that this came quite high, being recommended actions addressed to this specific group of adolescents.

OBJECTIVE: The purpose of this study was to analyze dental caries experience of adults living in the southeastern state of São Paulo, Brazil, according to some socio-demographic conditions of this population. MATERIAL AND METHODS: The sample consisted of 1,159 school teachers and workers (35 to 44 years old) from 29 cities of the state of São Paulo, Brazil. RESULTS: 92.3% were dentate and the DMFT index (number of decayed, missing and filled teeth) was 21.0 and the mean number of decayed teeth was 1.1, with no significant difference among adults from regions with and without fluoridation. Male subjects presented the highest mean values of "D" (decayed teeth) and "M" (missing teeth) components. The percentage of caries-free subjects was higher among white subjects, as well as the mean number of teeth present in the mouth. The mean values of the "F" component (filled teeth) [9.81] and present teeth [19.3] were higher for adults from fluoridated water regions. CONCLUSIONS: In this study, the worse condition observed was the early tooth loss in all groups. In addition, people with worse socio-demographic conditions had worse oral health conditions. It is expected that oral health programs targeted to this population could be established with the goal of improving the oral health conditions of this population and hence the maintenance of the teeth for a longer period in function.

This study evaluated dental caries according to the presence of natural teeth and sociodemographic conditions of an elderly population in the state of São Paulo, Brazil. Examinations were performed according to the World Health Organization's guidelines. The sample of 1,192 elderly individuals aged 65 to 74 years was stratified according to the presence of teeth and the following variables: gender, race, age, city size and Human Development Index (HDI). The Mann Whitney and Kruskal Wallis tests were applied at a confidence level of 95% for analysis of results. In the total sample, 68.9% (n=822) were edentulous; the mean of present teeth was 3.5 and the DMFT was 30.2, being 28.5 of missing teeth. Among dentate individuals (n=370), the mean of present teeth was 11.3, the DMFT was 26.2 and the missing component accounted for 20.7 teeth. The differences observed in the evaluated conditions should be highlighted: the mean number of present teeth was higher among younger individuals (from 65 to 69 years) [12.1] and among those living in cities with high HDI [12.9]; the DMFT was lower among men [24.9] and non-Caucasians [25.1]. Based on these findings, it may be concluded that specific dental programs should be established, with emphasis on oral health promotion and dental caries control, as well as public health policies that may enhance the access to the services provided.

This study aimed to investigate root caries prevalence in areas with and without water fluoridation at the Southeast region of São Paulo State, in the adult population, employees of public and private schools, and elderly population. Epidemiological surveys were conducted according to the World Health Organization guidelines (1997), including 1,475 dentate individuals aged 35 to 44 years and 65 to 74 years, living in cities representing the southeast of São Paulo State, with (n=872) or without (n=603) fluoridated water supply. Statistical analysis was performed by Mann-Whitney and Chi-square tests at a significance level of 5%. The prevalence of root caries was 15.6% for the 35-44-year-old age group and 31.8% for the 65-74-year-old age group . There were no statistically significant differences (p>0.05) in the occurrence of root caries according to water fluoridation, although individuals living at non-fluoridated areas presented higher percentage of missing teeth; also, there was higher mean number of intact roots at fluoridated areas (p<0.05). Most individuals with gingival recession, both adults and elderly, did not have root caries experience. In this study, root caries prevalence was lower in areas with fluoridated water. Due to the reduced prevalence of edentulism and increased number of people keeping their natural teeth for a longer period, a future increase in root caries is expected, highlighting the importance of studies related to water fluoridation and its relationship with the oral health of adults and elderly, especially referring to tooth root.

Os objetivos deste trabalho foram verificar a atividade de cárie, além de conhecer a experiência de cárie (ceod), necessidades de tratamento e defeitos de esmalte em pré-escolares de cinco anos de idade. Examinaram-se 624 crianças de Indaiatuba, São Paulo, Brasil, em 2004, selecionadas por meio de processo amostral aleatório sistemático. Para medir a experiência de cárie e necessidade de tratamento adotou-se os critérios da OMS. Para a atividade de cárie, optou-se por uma simplificação dos critérios de diagnóstico de Nyvad et al. Na análise estatística utilizaram-se os testes Mann Whitney e qui-quadrado com nível de significância de 5%. 40,5% dos pré-escolares apresentaram atividade de cárie. O ceod foi de 1,62 (IC95%: 1,35-1,89). Entre os doentes (ceod > 0) o ceod foi 3,81 (IC95%: 3,36-4,26), ainda neste grupo, 91,4% das crianças apresentaram atividade de cárie. O índice de cuidados foi de 12,3%. Sugere-se que medidas de prevenção e tratamento direcionadas a essa população continuem sendo priorizadas, uma vez que as medidas de controle e paralisação da cárie em seus estágios iniciais são bem conhecidas. Além disso, recomenda-se cuidado direcionado aos pré-escolares com maior experiência de cáries.

This study aimed to verify caries activity and analyze caries experience, treatment needs, and enamel defects in 5-year-old preschool children in Indaiatuba, São Paulo State, Brazil. 624 children were selected by systematic random sampling in 2004. WHO criteria were used to measure caries experience and treatment needs. Nyvad et al. diagnostic criteria were used to analyze caries activity. Mann-Whitney and qui-square tests were used to analyze the results, with 5% significance. 40.5% of schoolchildren displayed caries activity. The dfmt was 1.62 (95%CI: 1.35-1.89). Among children with dfmt > 0, the index was 3.81 (95%CI: 3.36-4.26), and 91.4% of these children presented caries activity. Care Index was 12.3%. These results suggest that treatment measures and health promotion should continue to be prioritized, since the control measures and caries interruption during the initial stages are well known. Dental care should especially target schoolchildren with more significant caries experience.

Observa-se uma ocorrência maior de cárie radicular nas últimas décadas, sendo este tipo de lesão mais comum em adultos e idosos. Em virtude disso, o objetivo deste estudo foi avaliar a prevalência de cáries radiculares em adultos e idosos da região Sudeste do Estado de São Paulo, Brasil. Exames epidemiológicos foram realizados seguindo recomendações da OMS, sendo examinadas 1.475 pessoas dentadas, dos grupos etários de 35 a 44 e de 65 a 74 anos. A prevalência de cáries radiculares foi de 15,6% e 31,8%, respectivamente, para 35 a 44 e 65 a 74 anos. A média de raízes cariadas e/ou restauradas foi de 0,36 para os adultos, maior entre os homens (p < 0,01) e de 0,82 para os idosos, sem diferença no gênero. A média de raízes cariadas foi de 0,18 e 0,53, respectivamente, para adultos e idosos; em ambos os grupos os valores foram maiores entre os homens (p < 0,01). Em razão das condições observadas, ressalta-se a necessidade de mais estudos relacionados com a saúde bucal de adultos e idosos, sobretudo da condição radicular.

In recent decades there has been an increase in the occurrence of dental root surface caries, especially among adults and senior citizens. This study aimed to identify root surface caries prevalence in adults and seniors from southeast São Paulo State, Brazil. An epidemiological survey was carried out among 1,475 dentate adults, ages 35 to 44 and 65 to 74, respectively, according to WHO criteria. Root surface caries prevalence was 15.6% and 31.8%, for the 35-44 and 65-74-year groups, respectively. The average rate for decayed and/or filled roots was 0.36 for the middle-aged adult group and higher in males (p < 0.01), as compared to 0.82 for seniors, with no difference by gender. The average rate of decayed roots was 0.18 and 0.53 for middle-aged adults and seniors, respectively; in both groups the levels were higher among men (p < 0.01). Further studies on oral health, mainly on root surface conditions, are essential in both middle-aged adults and senior citizens.

OBJETIVO: Verificar a prevalência de cárie, doença gengival e fluorose e dimensionar as necessidades de tratamento dos pré-escolares. MÉTODOS: Estudo transversal realizado a partir de um levantamento epidemiológico de saúde bucal em 2.805 crianças de 5 e 6 anos, matriculadas em pré-escolas municipais de Piracicaba, SP. As crianças foram examinadas por uma equipe de dez dentistas, treinados e calibrados. Foi empregada a técnica de consenso, aferindo-se o erro intra e inter examinadores pelo cálculo de percentagem de concordância. RESULTADOS: Obteve-se 44,3% de crianças livres de cárie aos 5 anos e 38,5% aos 6 anos de idade. O índice de cárie para a dentição decídua (ceo-d) foi 2,64 aos cinco anos e 3,07 aos seis anos, sendo que 31,9% e 37,9%, respectivamente, apresentaram ceo-d maior que 3. O maior percentual de necessidade de tratamento (45,3%) foi a indicação de restauração de uma superfície dentária. Quanto à saúde gengival, 68,6% e 72,6% das crianças aos 5 e 6 anos apresentaram sangramento gengival. A prevalência de fluorose observada foi de 2,6% aos 5 e 6,1% aos 6 anos. CONCLUSÕES: Há necessidade da implementação de ações e estratégias adequadas aos grupos de maior risco.

OBJECTIVE: To assess dental decay, gum diseases and fluorosis prevalence and evaluate treatment needs of public preschool children. METHODS: A cross-sectional epidemiological survey on oral health was conducted in 2,805 public preschool children aged 5 and 6 years in Piracicaba, Brazil. Children were examined by a team of ten trained dentists. It was applied a consensus technique and intra and inter agreement among examiners was assessed using the percentage of agreement. RESULTS: Of the total, 44.3% children were free of dental decay at the age of 5 and 38.5% at the age of 6. The deciduous decay teeth index (dmf-t) was 2.64 at the age of 5 and 3.07 at the age of 6, and 31.9% and 37.9%, respectively, presented dmf-t greater than 3. The largest percent of treatment need (45.3%) was surface restoration. Regarding gum health, 68.6% and 72.6% of children aged 5 and 6 years presented gum bleeding. The prevalence of fluorosis was 2.6% at the age of 5 and 6.1% at the age of 6. CONCLUSIONS: It is necessary to develop appropriate actions and strategies for higher risk groups.
