Anterior and Overall Bolton\u2019s ratio was measured in different malocclusion groups, and the results were compared with the standard Bolton values. Ratios were also calculated on gender basis and were compared with standard values.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n The mean overall Bolton\u2019s ratio was non-significant in the three groups. The mean anterior Bolton\u2019s ratio in the Class I malocclusion group and Class III malocclusion group when compared with the standard Bolton\u2019s ratio was found to be increased but the difference was found to be non-significant. In the Class II malocclusion group, a significant increase was found in the mean anterior Bolton\u2019s ratio as compared to the standard Bolton\u2019s ratio. On comparison of the mean overall Bolton\u2019s ratio among males in the Class II malocclusion group with the standard Bolton\u2019s ratio, the difference was found to be statistically significant while it was non-significant for Class I and Class III patients.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The findings of the present study confirm the reliability of Bolton\u2019s ratio in the Indian population. There were statistical non-significant differences among various groups for Overall ratio and for Anterior ratio except in Class II male patients, which was found to be significant.<\/jats:p>\n
