The objective of the study is to assess the prevalence of malocclusion and orthodontic treatment needs among 12-15 years old school children of Udaipur, India.
A cross-sectional descriptive survey was conducted among 887 subjects aged 12-15 years. The prevalence of malocclusion and orthodontic treatment needs was assessed using dental aesthetic index (World Health Organization, 1997). General information on demographic data was also recorded. Chi-square test, analysis of variance and Scheffe's test were employed for statistical analysis.
Malocclusion and orthodontic treatment need was reported among 33.3% of the study subjects. A significant age and gender difference depicting preponderance among younger age group and a male proclivity was experiential. A significant improvement in anterior crowding and largest anterior maxillary irregularity with age was documented. Males had a significantly higher prevalence of anterior crowding, midline diastema and largest anterior maxillary irregularity than females.
The prevalence of malocclusion and orthodontic treatment needs among school children of Udaipur city, Rajasthan, India was found to be 33.3%. A significant age and gender difference was observed in prevalence of malocclusion, crowding and largest anterior maxillary irregularity. Midline diastema showed a significant gender difference.
