Abstract
Introduction: Various studies have been conducted which show that interarch tooth size relation differ with population. The aim of this study was to find out Bolton ratio in Indian population. Methods: Measurement were taken from 50 study models of randomly selected males and females with class I molar and canine relationship with ideal overjet and overbite, who had not undergone any orthodontic or cosmetic dental treatment previously. Needle point dividers were used to measure the greatest mesio-distal diameter of all teeth. From the obtained data, the Kolmogrov-Smirnov test, standard error of mean, standard deviation, coefficient of variation, coefficient of correlation were measured and used to assign statistical significance. Results: Increased anterior ratio (79.2284) & decreased overall ratio (90.9464) in selected Indian population were found in relation to Bolton’s ideal ratio. Conclusions: - Differences between original Bolton ratio and obtained ratio for Indians were significant, specific standards for Indians might be needed.
