Association of Impacted Third Molars with Facial Growth Patterns among Adult Indian Patients - A Retrospective Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2019, Vol 6, Issue 10
Abstract
Introduction: The third molar (3M) varies more than other molars in terms of shape, size, timing of eruption, and tendency toward impaction. Hence, studies need to be carried out to clarify the association of the various patterns of facial growth with mandibular 3M impaction. Purpose: The purpose of this study is to relate the level of impaction of mandibular 3Ms and their inclinations to various patterns of facial growth among Indian patients. Materials and Methods: A total of 207 lateral cephalograms and optic pathway gliomas (OPGs) of patients were obtained from NISSAN Radiological and Diagnostic Centre. The OPGs were analyzed by a single examiner as per: (1) Angulations (using Quek’s analysis - beta angle, 2003). (2) Depth of 3Ms. The lateral cephalograms were assessed by a single examiner using: (1) Down’s analysis. (2) Beta angle. (3)Jarabak’s ratio. (4) Bjork’s analysis. The subjects were further classified into skeletal Class I, II, and III as well as into horizontal, vertical, and normal growth patterns. The final study data were subjected to a Pearson correlation test to check the association between the 3M impactions and various angles. The values found significant were coded into ordinate data and Kendall’s Tau-B Test was done. Results: Statistically, significant correlation was found between depth of impacted mandibular 3Ms and facial angle, Y-axis, cant of occlusion, angle of convexity, and gonial angle. Conclusion: Greater incidence of 3Ms was found to be at position B and C in Class II patients as compared to Class I and III patients. Furthermore, patients showing vertical growth pattern were found to have increased percentage of mandibular 3M impactions.
