Dental caries and calculus status in children studying in Government and Private Schools in Malappuram, Kerala, India

Background: Dental caries status in children is influenced by a number of risk factors such as sex, age, socioeconomic status, diet, and oral hygiene practices. The objective of the study was to assess and compare the prevalence of dental caries and calculus in 12-13 year old school children. Materials and methods: A sample of 761 children aged 12-13 years of both sexes from government and private schools. Clinical examination was carried out using the DMFT index for assessing the caries prevalence and Calculus component of Simplified-Oral Hygiene Index was used for assessing calculus in these children. Results: The prevalence of dental caries was seen more in children studying in government schools than in private schools which was statistically significant (p=0.018). When the gender differences were compared it was seen that girls showed a higher prevalence of dental caries (66.37% in private schools; 87.58% in government schools) than boys (64.47% in private schools; 71.98% in government schools). There was no significant difference seen in the prevalence of calculus between government and private school children. Conclusion: High prevalence of dental caries was found in these school children which suggested a poor performance of oral hygiene practices in them.
