Methods: 100 school children of age group 13-16yrs from Bagalkot district were selected and divided into 50 boys and 50 girls. The subjects were interviewed using- Questionnaire having questions concerning smile, dental appearance and desire for orthodontic treatment. A cross-cultural index, "Dental Aesthetic Index (DAI)" was also assessed. The relationship between Dental aesthetic index and the self-assessment of relative appearance of teeth was determined.
Results: Statistically significant correlations were observed between subjective assessments of dental appearance and DAI (p = 0.0007) and need for orthodontic treatment and DAI (p = 0.0006). The strongest correlations were found between DAI and comparative evaluations of dental appearance (p < 0.005).
Conclusion: This study has shown significant correlations between DAI and subjective perceptions of dental appearance.
