A study to correlate the incidence of cross arch balance and working side occlusal wear facets among different age groups: An in vivo study.

ABSTRACT

Introduction: The prevalence of group function and canine guided occlusion is common in natural dentition, but cross arch balance is not often seen. Hence, a study was carried out with following objectives: Analysis of incidence of cross arch balance in different age groups and working side occlusal wear facets in following subjects. Materials and Methods: A total of 200 patients with natural dentition were included in the study. Subjects with cross arch balance were analyzed for working side occlusal wear facets. Data were analyzed statistically by Chi-square test. Results: The incidence of cross arch balance in the study group was 0.7%. On examination, subjects with group function on the working side and cross arch balance on the non-working side had more occlusal wear facets. Conclusion: From the study, it was observed that there was no significant variation in the number and extent of wear facets between the cross arch and without cross arch subjects due the smaller sample size hence it was difficult to conclude the relationship non-working side contact as interference and its influence in wearing of dentition in this study.
