Objective: The present study was undertaken to assess whether Boltons ratio can be applied to Chattisgarhi population and if values obtained are significantly different from that of Boltons established values, then to establish Boltons standards for the Chhattisgarhi population and also to determine if sexual dimorphism exists in overall and anterior ratios.
Study Design: 120 subjects (60 male and 60 female) between 17-25 years of age having normal occlusion were selected. Boltons anterior and overall ratio was calculated on study models and values obtained were statistically analyzed for co-efficient of variation, standard deviation and mean values. This data was compared with standard Bolton’s values.
Results: The combined anterior and overall ratios of Chhattisgarhi population did not differ significantly from that of Boltons sample, however significant sexual dimorphism was noted both in anterior and overall ratios among males and females. Conclusion: Boltons anterior and overall tooth size ratios can be applied to Chhattisgarhi population.

Keywords: Bolton ratio, Chhattisgarhi population.
