Oral health status and treatment needs among 12- and 15-year-old government and private school children in Shimla city, Himachal Pradesh, India.
OBJECTIVE
To assess the dental caries, periodontal health, and malocclusion of school children aged 12 and 15 years in Shimla city and to compare them in government and private schools.


METHODS
A cross-sectional study of 12- and 15-year-old children in government and private schools was conducted in Shimla city, Himachal Pradesh, India. A sample of 1011 school children (both males and females) was selected by a two-stage cluster sampling method. Clinical recordings of dental caries and malocclusion were done according to World Health Organization diagnostic criteria 1997. Periodontal health was assessed by Community Periodontal Index of Treatment Needs index. The data collected was analyzed by SPSS package 13. The statistical tests used were t-test and Chi-square tests.


RESULTS
The prevalence of dental caries was 32.6% and 42.2% at 12 and 15 years, respectively. At the12 years of age, the mean decayed, missing, filled teeth was 0.62 ± 1.42 and it was 1.06 ± 2.93 at 15 years of age. Females had higher level of caries than males at both the ages. At both ages, mean of decayed teeth was statistically higher in government schools as compared with private schools. Children in government schools had significantly less number of mean filled teeth at both ages as compared with private schools. The healthy component of gingiva was present in higher percentage of children in private schools as compared with government schools at both the age groups. The prevalence of malocclusion among the 12- year-old (58.1%) was more as compared with that among the 15-year-old (53.5%).


CONCLUSIONS
The caries experience of 12- and 15-year-old children was low but the prevalence of gingivitis and malocclusion was quite high. Effective oral health promotion strategies need to be implemented to improve the oral health of school children further in Shimla city.
