Introduction:
Dental caries is a common dental disease, which occurs during childhood and continues to be a major public health problem. The prevalence of dental caries was associated with oral hygiene practice, sugar consumption and implementation of the preventive oral health program.
Aim:
The purpose of this study was to assess the prevalence of dental caries in school children aged between 6-14 years using the International Caries Detection and Assessment System (ICDAS II).
Materials And Methods:
The study population consisted of 2796 school children living in Pallikkaranai, Chennai, India and studying in government recognized schools. Each student was examined by a single examiner using ICDAS system under natural light during normal school hours.
Results:
The prevalence of dental caries was 68.8% in the total surveyed population. The gender-wise prevalence of dental caries shows, females to have slightly higher prevalence than male. The prevalence of dental caries at the age group of 6 years was 57%, seven year 67%, eight year 63%, nine year 74%, 10 year 76%, 11 year 74%, 12 year 69%, 13 year 71%, and 14 year 69%. The distribution of CARS (Caries associated with Sealants and Restorations) in the surveyed population was only 1.4.
Conclusion:
The distribution of non-cavitated/early enamel lesions was higher in the studied population and indicated a requirement of a sustained dental health preventive program targeting specific segments of the population.
