Objective: To compare the Bolton ratio between Punjabi and Pathan population reporting to Armed Forces Institute of Dentistry (AFID) Rawalpindi.
Study Design: Comparative study.
Place and Duration of Study: Department of Orthodontics at AFID Rawalpindi from May 2014 till Dec 2014.
Material and Methods: On the basis of inclusion criteria; 107 good quality study casts out of 150 patients were selected. They were divided into Punjabi and Pathan groups. Both the Overall Bolton Ratio and Anterior Bolton Ratio were calculated for both of these groups. For comparison of their means an independent t test was applied. A p value was determined for anterior and overall Bolton Ratios at 95% confidence interval.
Results: Our sample consisted of 52.3% females and 47.7% males. The percentage of the Punjabi population was 59.9% (n=64) and Pathan population was 40% (n=43). Our mean Overall Bolton ratio calculated was 90.69%. The mean Anterior Bolton ratio calculation was 78.93%. The mean overall Bolton Ratio for Punjabi population was 90.24 and for Pathan population the Ratio was 91%. The mean anterior ratio for Punjabi population was 78.08 and for Pathan population the ratio was 80.19. The p value for overall ratio was .119 while for the anterior ratio the p value was .091.
Conclusion: Differences were noted in Bolton Ratio (Overall Bolton Ratio and Anterior Bolton Ratio), but they were statistically insignificant.
