Aims: This study aims to evaluate the Bolton ratio in Beed population in Maharashtra with different malocclusion. Materials and Methods: Fifty study casts were taken from the patients undergoing orthodontic treatment, and individuals were divided into three groups: Group I (Angle's Class I, n = 25), Group II (Angle's Class II, n = 25), and Group III (mean of Group I and Group II). Statistical Analysis Used: ANOVA and Tukey's test. Results: A mean total Bolton ratio of 93.05 ± 5.87 and a mean anterior Bolton ratio of 81.08 ± 5.93 were found for the sample; significantly, higher mean anterior tooth ratios were found for Group I (Angle's Class I) patients (P < 0.03). Conclusions: Mean anterior tooth size discrepancy for Angle Class I individuals was significantly greater compared to Bolton's mean anterior ratio.
