Abstract
BACKGROUND: Many studies have been conducted in India to know the prevalence of malocclusion and the orthodontic treatment needs using dental aesthetic index (DAI), but no study so far has been conducted in Shimla city, Himachal Pradesh. OBJECTIVE: To know the prevalence of malocclusion and orthodontic treatment needs among 16- and 17 year-old school-going children in Shimla city, Himachal Pradesh. MATERIALS AND METHODS: The study was carried out on 622 (365 boys and 257 girls) school children, aged 16 and 17 years, from February 2009 to May 2009. Type III examination was conducted and the assessment of malocclusion was done according to the DAI. RESULTS: 20.28% of the male and 24.52% of the female students in the sample were affected with malocclusion. The mean DAI scores of the male and female children were 22.26 and 21.79, respectively. Distribution of the four DAI grades was as follows: DAI-I (no abnormality or minor malocclusion) 79.58%, DAI-II (definite malocclusion) 16.39%, DAI-III (severe malocclusion) 3.69%, DAI-IV (very severe/handicapping malocclusion) 0.34%. CONCLUSION: The present study shows that 20.42% of the children examined had malocclusion which required treatment.
