Prevalence of enamel defects and the relationship to dental caries in deciduous and permanent dentition in Indaiatuba, Sac, Paulo, Brazil

The aim of this study was to determine the prevalence of hypoplasia, demarcated opacity and dental fluorosis among schoolchildren with deciduous and permanent dentition. The association between enamel defects and dental caries was also verified. The sample consisted of 624 schoolchildren aged 5 and 309 aged 12. The dmft and DMFT indexes were used to assess dental caries prevalence, DDE to assess enamel defects, and Dean to assess fluorosis. Chi-squared test was used to test significance (p < 0.05) and odds ratio to analyze prevalence of dental caries and enamel defects. A positive association between dental caries and enamel defects (hypoplasia, demarcated opacity and dental fluorosis) was observed for schoolchildren aged 5. However, only hypoplasia and demarcated opacity were associated with caries experience in permanent dentition. The results of this study indicated that children had increased odds of dental caries when enamel defect was present, both in deciduous and permanent dentition; further studies are needed to give evidence to this association.23243544

Developmental enamel defects and their impact on child oral health-related quality of life

This cross-sectional study assessed the impact of Developmental Enamel Defects (DED) on Child Oral Health-Related Quality of Life (COHRQoL). A sample of 944 11- to 14-year-old Brazilian schoolchildren was examined for the prevalence and severity of DED. The children completed the Child Perceptions Questionnaire (CPQ11-14), and socioeconomic status was also collected using a questionnaire. Poisson regression models were used to assess the association between DED and overall and domain-specific CPQ11-14 scores. The prevalence of DED was 19.7%. In general, children with DED did not indicate any decrease in self-perception. However, this condition was associated with an impact on the functional limitation domain. The presence of DED may cause negative impacts on a child's perception of oral health and on their daily performance

Dental caries and dental fluorosis in 7-12-year-old schoolchildren in Catalão, Goiás, Brazil Cárie e fluorose dentária em escolares de 7 a 12 anos de idade em Catalão, Goiás, Brasil

INTRODUCTION: Over the last two decades, the prevalence of dental caries in children has decreased and the prevalence of dental fluorosis has increased. Knowledge on the epidemiologic conditions of a population is fundamental for the planning of health programs. OBJECTIVES: To determine the prevalence of dental caries and dental fluorosis among schoolchildren, in Catalão, Goiás, Brazil. METHODS: A random sample of 432 schoolchildren aged 7-12-years old was obtained. WHO (1997) criteria for dental caries and fluorosis diagnosis were used. RESULTS: The DMFT indexes were 0.97; 1.20; 1.80; 1.62; 2.40 and 2.51 for 7, 8, 9, 10, 11 and 12 years old, respectively. Analysis of dental fluorosis for the same ages presented higher prevalence at 12 years old and for the female gender. The percentage of questionable dental fluorosis (Dean's classification) was 34.0%. Only 3% of the sample presented dental fluorosis with scores very mild, mild and moderate. CONCLUSIONS: The prevalence of caries in schoolchildren of Catalão, Goiás, Brazil, was low. In average, private schools showed better results than public schools; however, all schools presented a low DMFT index. In this study, dental fluorosis is not a public health problem and has not damaged dental esthetics.<br>INTRODUÇÃO: Nas últimas duas décadas, a prevalência de cárie dentária tem diminuído e a prevalência de fluorose dentária tem aumentado. Para se planejar programas de saúde é fundamental conhecer o perfil epidemiológico das populações. OBJETIVOS: Determinar a prevalência de cárie dentária e fluorose dentária em escolares do município de Catalão, Goiás, Brasil. MÉTODOS: A amostra randomizada foi composta por 432 escolares de 7 a 12 anos de idade. Os critérios utilizados para determinar a prevalência de cárie dentária e fluorose seguiram a metodologia proposta pela OMS, 1997. RESULTADOS: Os valores do Índice CPOD foram de 0,97; 1,20; 1,80; 1,62; 2,40 e 2,51 para as idades de 7, 8, 9, 10, 11 e 12 anos, respectivamente. Considerando o diagnóstico de fluorose dentária para as mesmas idades, houve maior prevalência nos estudantes de 12 anos de idade e no gênero feminino. A porcentagem de fluorose dentária questionável (classificação de Dean) foi de 34,0%. Somente 3,0% da amostra total, apresentou fluorose dentária nos escores muito leve, leve e moderado. CONCLUSÕES: A prevalência de cárie dentária em escolares de Catalão, Goiás, Brasil foi baixa. As escolas particulares mostraram melhores resultados que as escolas públicas, entretanto, em todas elas se verificou baixos valores do Índice CPOD. Neste estudo, a fluorose dentária não tem causado problemas à estética dental e não se caracterizou em um problema de Saúde Pública

Declínio de cárie em escolares de 12 anos da rede pública de Goiânia, Goiás, Brasil, no período de 1988 a 2003 Caries decline in 12 year-old schoolchildren from Goiânia, Goiás, Brazil between 1988 and 2003

OBJETIVOS:Investigar a prevalência e severidade da cárie dentária em crianças de 12 anos em Goiânia no período 1988-2003. MÉTODOS: Foram analisados os dados de todos os levantamentos epidemiológicos realizados em escolares de 12 anos de escolas públicas do município em 1988, 1994, 1998 e 2003, obtidos a partir de fontes secundárias. Goiânia possui água fuoretada desde 1985. As variáveis incluídas na análise foram a prevalência de indivíduos livres de cárie (CPOD=0) e a severidade da cárie através do Índice CPOD. RESULTADOS:O percentual de escolares livres de cárie teve um aumento de 21% de 1994 (10%) a 2003 (31%). Houve uma redução de 70,6% na média do índice CPOD de 1988 a 2003. As médias foram 8,3 em 1989, 4,59 em 1994, 3,07 em 1998 e 2,43 em 2003. Em todos os levantamentos os principais componentes foram os cariados (predomínio em 1988 e 2003) e os obturados (predomínio em 1994 e 1998). No período de 1988 a 2003 houve redução de 81,9% na média do componente cariado, 66,7% do perdido por cárie e 31,8% do obturado. CONCLUSÃO:Houve queda acentuada na prevalência e severidade da cárie dentária em escolares de 12 anos da rede pública em Goiânia no período 1988-2003, seguindo a tendência nacional.<br>OBJECTIVE:to investigate the trends in the prevalence and severity of dental caries in 12-year-old schoolchildren between 1988 and 2003. METHODS:The study included secondary data of all epidemiological surveys carried out in 12-year-old children attending public schools in Goiânia, Brazil in 1988, 1994, 1998, and 2003. The city has had fluoridated water since 1985. Variables analyzed were prevalence of caries-free individuals (DMFT=0) and caries severity using the DMFT index. RESULTS:Percentage of caries-free schoolchildren increased 21% from 1994 to 2003. Mean DMFT index decreased 70% from 1988 to 2003. Mean values were 8.3 in 1989, 4.59 in 1994, 3.07 in 1998, and 2.43 in 2003. In all surveys the main components were decayed (in 1988 and 2003) and filled teeth (in 1994 and 1998). Between 1988 and 2003 there was a 81.9% reduction in the mean number of decayed teeth, 66.7% in the missing teeth due to caries, and 31.8% in the filled teeth. CONCLUSION:There was a substantial decline in the prevalence and severity of dental caries in 12-year-old schoolchildren from public schools in Goiânia from 1988 to 2003, following the national trend
