Abstract

Aim: To evaluate and compare tooth size discrepancies and arch parameters among Class I, Class II Div I, Class II Div II and Class III malocclusion groups in the Central India population.
Materials and Methods: The study included 160 subjects (aged 13–15 years) evenly divided among Class I, Class II Division I, Class II Division II, and Class III malocclusion groups. Mesiodistal tooth width, Bolton’s ratios, arch length, and arch width were measured using standardized orthodontic methods.
Results: Statistically significant differences were observed across malocclusion groups in certain parameters, highlighting the need for population-specific diagnostic norms.
Conclusion: These findings provide valuable insight into tooth-arch relationships within the Central India population and underscore the importance of individual diagnostic assessment in orthodontic planning.
