Dental caries prevalence was assessed by the DMFT index as recommended by the World Health Organization (WHO).

Chi-square test and Fisher’s exact test were used to analyze the association of the variables as well as odds ratio (OR). Results: Caries prevalence was 70.5%, and mean DMFT was 2.09. Maternal educational level and time of the last visit to the dentist were positively associated with DMFT index.
