Background. Information regarding Early Childhood Caries (ECC) in Mexican preschool children and its impact on quality of life is scarce. Aim. To evaluate the ECC prevalence and its impact on OHRQoL in 3-5-yr-olds Mexican children according to disease severity. Design. Caries was determined at two thresholds: 1) children with at least one caries lesion (ICDAS-1-6), and 2) children with at least one lesion in dentin (ICDAS-3- 6). OHRQoL was assessed through the Mexican Early Childhood Oral Health Impact Scale (M-ECOHIS). Associations among caries severity, M-ECOHIS and other variables were assessed by ordinal logistic regression. Results. 409 children participated (53.8% girls, 46.2% boys). Caries prevalence was 82.2% considering all lesions, and 45.0% for dentinal lesions. Significant linear trends (p<0.05) among caries levels and categories of exposure, were found for socio-economic variables, dietary habits, and tooth-brushing habits. Attending rural private schools (OR=1.39, 95%CI=1.11-1.72 p<0.01), two main meals/day (OR=2.75, 95%CI=1.26-6.03 p=0.01) and unsupervised tooth brushing (OR=3.20, 95%CI=1.96-5.24 p<0.01) increased the risk to have high caries severity levels. Conclusions. M-ECOHIS was significantly associated with caries severity. Type of school, age groups, parents’ educational level, family income, and living conditions were correlated with caries, showing how distinctive risk indicators were associated with different caries stages.
