title: Prevalence of Dental Caries Among Primary School Children of India - A Cross-Sectional Study.
abstract: BACKGROUND
  In India, the trend indicates an increase in oral health problems especially dental caries, which has been consistently increasing both in prevalence and in severity. Children of all age groups are affected by dental caries. It becomes imperative to collect the data on prevalence of dental caries and treatment needs to provide preventive care.
  
  
  OBJECTIVE
  To assess the prevalence of dental caries and treatment needs of 6-11years old Indian school children.
  
  
  METHODS
  This was a cross-sectional study. Sampling frame consisted of 6-11years old primary school children. Study sample consisted of 13,200 children selected from 10 talukas of Belgavi District, Karnataka, India. Clinical examination for dmft and DMFT was carried out in the school premises by five teams, each consisting of one faculty, three postgraduate students and five interns from the KLE VK Institute of Dental Sciences, Belagavi, Karnataka, India. The examiners were trained and calibrated by the principal investigator. Statistical analysis was done using Chi-square and t-test.
  
  
  RESULTS
  The overall caries prevalence was 78.9%, mean dmft was 2.97±2.62 and mean DMFT was 0.17±0.53. The decayed teeth component was the principal component in both dmft and DMFT indices. The mean dmft in boys was higher compared to girls and it was found to be statistically significant (p<0.05).
  
  
  CONCLUSIONS
  This study provided us with the baseline data, using which treatment was provided to all the children screened. The children were provided treatment at the camp site/dental hospital/satellite centers and primary health care centers according to the facilities available.
