The data was collected and recorded on a preformed proforma sheet. The data was then processed and analyzed using the chi square test and the Z test. The level of significance was set at p=0.05 Results: The prevalence of dental caries among the 12 and 15 year old school children was 46.9% and 48.5% respectively. In the 12 year old age group, females had a higher prevalence (53.5%) while in the 15 year old age group, males had a higher prevalence (50.9%).
