Disparities in caries experience in childhood to communal level, Metropolitan Region, Chile
Objectives: To describe the disparities in caries experience in children from 1 to 6 years of age, between communes of the Metropolitan Region.
Methods: A multilevel cross-sectional study was conducted, considering three levels: administrative communities (commune), educational establishment (school and pre-school) and child. Children from 1 to 6 years of age were selected using a stratified probability sampling using the Community Human Development Index (HDIc) for stratification in 13 communes, and with educational institutions clustered within administrative dependence, considering the child as analysis unit. Information was collected through a clinical-examination and caregiver interview. Clinical exam was performed in each school by a dentist and an assistant. Dmft-index for caries experience and Significant Caries Index (SiC-index) for severity were calculated. Absolute and relative disparities were estimated. Additionally, Slope Index of Inequality (SII) was calculated.
Results: 2275 children were examined. Dmft-index global was 1.88 (IC95% 1.76, 2.01) for all ages combined. Absolute disparities between extreme communes was 2.23 (IC95% 1.56, 2.90), observing the highest dmft in Lampa (dmft=3.24). The lowest dmft was found in Recoleta (dmft=1.01). The relative disparity was 3.21, in the commune with the worst caries situation observed (Lampa) there are three times more caries experience in children of 1 to 6 than in the commune with the best situation of caries observed (Recoleta). Highest differences were observed for SiC for absolute disparities (4.85 IC95% 4.23, 5.47). SII for dmft was -1,16 and -2,64 for SiC.
Conclusions: Is possible to observe differences in caries experience between communes in Metropolitan Region for dmft-index and SiC-index. In addition, social disparities were observed between communes according to HDIc.
