This report describes the prevalence of non‐cavitated and cavitated carious lesions in 911 randomly selected children in grades one through three on the Island of Montreal. Quebec, Canada. The criteria for diagnosis were developed for a longitudinal epidemiological study of restorative treatment decisions by dentists practising under a provincial dental insurance program for children. The intra‐ and inter‐examiner reliability correlation coefficients of the two examiners were excellent (Kappa 0.80). The most frequent carious lesion found in the examined children were non‐cavitated carious lesions (incipient) within 1.5 of the gingival line on smooth tooth surfaces, and stained or non‐cavitated carious lesions on pits and fissures. Out of 911 children in the study, 19.6% had sealants. Children whose parents completed a university education had a significantly lower prevalence of non‐cavitated and cavitated carious lesions and fillings, and a significantly higher mean number of sealants than children whose parents had only primary school education. Education status of the parents was a significant risk marker of children with high caries experience and these children had a significantly higher mean number of non‐cavitated carious lesions. This study has found that non‐cavitaled carious lesions arc significantly more prevalent than cavitated carious lesions in children.
