          Abstract

          The objective of the study was to develop regression models to describe the epidemiological profile of dental caries in 12-year-old children in an area of low prevalence of caries. Two distinct random probabilistic samples of schoolchildren (n=1,763) attending public and private schools in Piracicaba, Southeastern Brazil, were studied. Regression models were estimated as a function of the most affected teeth using data collected in 2005 and were validated using a 2001 database. The mean (SD) DMFT index was 1.7 (2.08) in 2001 and the regression equations estimated a DMFT index of 1.67 (1.98), which corresponds to 98.2% of the DMFT index in 2001. The study provided detailed data on the caries profile in 12-year-old children by using an updated analytical approach. Regression models can be an accurate and feasible method that can provide valuable information for the planning and evaluation of oral health services.

          El objetivo de este estudio fue desarrollar modelos de regresión para describir el perfil epidemiológico de caries dentales en niños de 12 años en un área de baja prevalencia de caries. Fueron estudiados dos muestras distintas aleatorias y probabilísticas de niños escolares (n= 1.763) que estudiaban en colegios públicos y privados en Piracicaba, Sureste de Brasil. Modelos de regresión fueron estimados como una función de los dientes más afectados usando datos colectados en 2005 y fueron validados usando una base de datos del 2001. El índice promedio (SD) de DMFT fue 1,7 (2,08) en 2001 y las ecuaciones de regresión estimaron un índice de DMFT de 1,67 (1,98), lo cual corresponde a 98,2% del índice en 2001. El estudio provee datos detallados sobre el perfil de caries en niños de 12 años usando una aproximación analítica. Los modelos de regresión pueden ser un método confiable y factible que puede proporcional información valiosa para la planificación y evaluación de servicios de cuidado oral.

          O objetivo do estudo foi desenvolver modelos de regressão para delinear o perfil epidemiológico da cárie dentária em localidade com baixa prevalência de cárie aos 12 anos de idade. Foram examinadas duas amostras probabilísticas (n=1.763) de indivíduos de escolas públicas e privadas de Piracicaba,(SP). Dados sobre os dentes mais afetados foram coletados em 2005 e validados utilizando um banco de dados (2001). A média (dp) do CPOD foi de 1,7 (2,08) em 2001 e os modelos de regressão desenvolvidos estimaram um CPOD de 1,67 (1,98) em 2005, o qual representa 98,2% do CPOD em 2001. Os resultados apresentaram detalhes do perfil da cárie dentária aos 12 anos, usando uma abordagem analítica atual. Os modelos de regressão poderiam ser considerados como uma forma acurada e factível no auxílio do planejamento e avaliação dos serviços em saúde bucal.

          Introducing the Significant Caries Index together with a proposal for a new global oral health goal for 12-year-olds.

          To describe a new index, the 'Significant Caries Index' (SiC Index) with the intention of focusing attention on those individuals with the highest caries scores in each population. Attention is drawn to the skewed distribution of dental caries within a given population, indicating that there are still large groups of individuals who have considerably more caries than the WHO/FDI target level of DMFT 3 by the year 2000. The index is calculated as follows: individuals are sorted according to their DMFT values. The one third of the population with the highest caries score is selected and the mean DMFT for this subgroup is calculated. This value constitutes the SiC Index. The SiC Index can be easily calculated and used as a measure for future oral health goals. The SiC Index should be less than 3 DMFT in the 12-year-olds in a given population and it is hoped that this global oral health goal is reached at the latest by the year 2015.

            Measuring inequalities in the distribution of dental caries.

            To evaluate different measurements of prevalence and inequality in the distribution of dental caries as to their partial collinearity, and ability in expressing associations with the supply of fluoridated tap water, indices of socioeconomic status and provision of dental services. The DMFT, the Significant Caries (SiC) Index, the proportions of children with high- (DMFT > or = 4) and rampant- (DMFT > or = 7) caries experience, caries-free children (DMFT = 0), the Gini coefficient and the Dental Health Inequality Index (DHII) were the dental outcomes appraised in a sample comprising 18 718 oral examination records for 11- and 12-year-old schoolchildren in 131 towns of the state of São Paulo, Brazil. Spatial data analysis assessed the association between aggregate figures of dental indices and several covariates. The DMFT, the SiC Index and the proportions of children with high- and rampant-caries experience presented strong linear associations (Pearson r near or higher than 0.95), and an analogous profile of correlation with indicators of socioeconomic status, dental services and access to fluoride tap water. The same was observed for the DHII, the Gini coefficient and the proportion of caries-free children. These observations involve the perception of variables in each set as interchangeable tools for ecological studies assessing factors influencing, respectively, prevalence levels and inequality in the distribution of dental disease. An improved characterization of the skewed distribution of caries experience demands the concurrent estimation of figures of prevalence and inequality in dental outcomes. This strategy may contribute to the design of socially appropriate programmes of oral health promotion. Copyright Blackwell Munksgaard, 2004

              Grouping of tooth surfaces by susceptibility to caries: a study in 5–16 year-old children

              Background The decline in caries has slowed and this may be indicative of variation in the susceptibility of differing teeth to caries. This study tests the hypothesis that in children, there are groups of tooth sites that exhibit differences in caries susceptibility. Methods Probit analysis of caries data collected from a 4-year longitudinal study of 20,000 schoolchildren aged between 5 and 16 years in 10 differing locations in the United States. Results The development of dental caries within the mouth followed a fixed hierarchy indicating that tooth surfaces show variation in caries susceptibility. Certain teeth and tooth sites have similar susceptibilities and can be grouped, the sizes of the groups vary. The most susceptible group consists of six tooth surfaces: the buccal pits and occlusal fissured surfaces of the first molar teeth. The second group consisted of 12 sites on the second molar and premolar teeth. The group formed by the least susceptible sites included the largest number of tooth surfaces and consists of the majority of the lower anterior teeth and canines. Conclusion Variation in the caries susceptibility of tooth surfaces exists. Surfaces can be grouped according to caries susceptibility. An effect that reduces the cariogenic challenge of one of the sites within a group is likely to affect all the other sites within the particular group.
