Caries risk profiles in 2- to 6-year-old Greek children using the Cariogram

Abstract

To assess the caries risk profiles in 2- to 6-year-old Greek children using a computer-based program and to evaluate the contribution of various risk factors. The study group consisted of 814 preschool children. A questionnaire on family, demographic and socioeconomic factors, general health, oral hygiene and dietary behavior was completed by the parents. Children were examined for cavitated and white-spot lesions (WSL). Salivary mutans streptococci (MS) and buffer capacity were estimated. Caries risk profiles were assessed with Cariogram. Cavitated lesions were found in 30% of the children; WSL were found in 26% of those included. MS and low buffer capacity were detected in 28% and 26% of the children, respectively. The majority (70%) displayed neglected oral hygiene. Based on the questionnaires, 83% of the children had a cariogenic diet, and 17% did not use any form of fluoride. The Cariogram revealed that 26% of the children had high caries risk, while only 9% exhibited low caries risk. The most significant caries risk variables, determined by regression analysis (R(2)=0.88), were insufficient fluoride exposure (ß=0.160) and the presence of WSL (ß= 0.159). One-fourth of the children were categorised as high caries risk. The presence of WSL and lack of fluoride exposure were the most significant caries risk determinants.
