The aim of this study was to determine the caries situation of three-year-old preschool children residing in low socioeconomic status districts in Lima, Peru. The study is a crosssectional analysis of the caries situation of suburban areas of Lima. A stratified sampling procedure by geographical distribution, considering healthcare centers with a motherand- child health clinic and surrounding preschools as factors, identified 45 randomly selected preschools, of which 17 accepted to participate. Children from 3-year-old classrooms were examined by two independent calibrated dentists using the Caries Assessment Spectrum and Treatment (CAST) instrument at their premises using artificial light, sterile examination mirrors and gauze for drying each tooth before evaluation. ANOVA and the Tamhane method were used to analyze the data. 308 children, mean age 3.4 years (min: 3 years; max: 3 years, 7 months), were examined. The sample prevalence of enamel and dentine carious lesions (CAST code 3-7) was 91.2% while the prevalence of dentine carious lesions (CAST code 4-7) was 58.8%. The mean number of teeth with cavities that had reached the pulp and those that had an abscess or fistula were 2.0% and 0.5% respectively. The majority of enamel and dentine carious lesions were observed in molars. The CAST severity score was 7.0. Mean examination time was 57 seconds. The burden of dental caries of the children at this young age was high.
