Result: the study revealed 4.84% of the students were free of caries while caries prevalence is 95.16% which is very high and coincide when comparing it to control group from other study in the same area. The mean of DMFT/dmft is low 0.24/0.59 and the reason for that may be various, ranging from biochemical differences in salivary buffering to differences in living environment, dietary and hygiene habits.
