Black stain and dental caries in primary teeth of Tunisian preschool children.

To assess the prevalence of black tooth stains and to investigate its correlation with caries experience in the primary dentition of 3-5-year-old children in the region of Monastir, Tunisia. It was a descriptive cross-sectional study involving children in preschool establishments in Monastir, Tunisia. It consisted of an oral examination of 393 children and data collection through a questionnaire completed by parents. ANOVA test and Pearson Chi-square test were used to assess the prevalence of black stains and its association with dental caries. The overall mean decayed, missing, and filled teeth (dmft) index was 1.42 ± 0.1. Caries prevalence was 49.9%. Of all the children involved, 6.1% had black stains. A statistically significant relationship was found between black stain and the prevalence of early childhood caries (p = 0.047). However, the association with the dmft index was not statistically significant (p = 0.08). Preschool children with black tooth stain had lower dental caries experience. The results of the present study suggest that black stains are a protective factor for early childhood caries. More studies are needed to explore the risk factors of black stains.
