Abstract :

AIM: To assess the reliability of Predicted Arch Length (PAL) by linear regression equation based on measured ICW and determines gender by means of measured ICW and IMW in North Gujarat population. MATERIALS AND METHODS: The dental casts of 50 patients were selected. ICW, IMW and AL on each dental cast were measured. Regression analysis was done to analyze the linear regression equation for PAL and measured arch length (MAL). RESULT: Statistically, significant difference was present between PAL and MAL in upper and lower arch. ICW and IMW between male and female subjects in both arch showed no difference. CONCLUSION: showed PAL was higher and significant than MAL. Weak correlation was found with the given formula by Paulino V. et al so, this study established a new formula for north Gujarat population and concluded that ICW and IMW can be used for sex determination
