Results: The prevalence of enamel opacities was 18.2%. At 12 years of age, the prevalence was 17.9%, whereas at 15 years it was 18.6%. The tooth prevalence of enamel opacities of the entire sample was 11.8%. At 12 years tooth prevalence was 10.9% and at 15 years it was 12.7%. There was a significantly higher prevalence of Enamel hypoplasia among males at both the age groups. The diffuse type of enamel opacity was the most commonly seen at both the age groups.
