Epidemiology of dental caries in Chandigarh school children and trends over the last 25 years.

ABSTRACT

The prevalence of dental caries in 6, 9, 12 and 15-year-old school children of Chandigarh, selected on a randomized basis was evaluated using Moller's criteria (1966) and correlated with the various risk factors. The mean deft was found to be 4.0 +/- 3.6 in 6 year old and 4.61 +/- 3.14 in 9 year old, whereas the mean DMFT in 12 and 15 year old was found to be 3.03 +/- 2.52 and 3.82 +/- 2.85 respectively. The high prevalence of dental caries in these children was attributed to the lack of use of fluoride toothpaste (80% children), lack of knowledge about etiology of dental caries (98%) and frequency of sugar exposures up to more than five times per day (30%).
