Assessment of Variables in Mesioangular Impactions and Vertically Erupted Mandibular Third Molars

Background Impacted third molars may be responsible for various problems within the oral cavity. Impaction may be due to inadequate space or varied angulations. Assessment of variables contributing for impaction may influence the fate of impacted third molars. MethodologyRetrospective analysis of panoramic radiographs of adolescents in Indian population subpopulation was done to evaluate angulation, mesiodistal width of crown, retromolar space, gonial angle among the mesioangular impacted teeth and vertically erupted teeth. Patients with syndromes associated with impactions were excluded from the study. Results In the impacted group angle of inclination was more, mesiodistal dimension and gonial angle was more compared to the non impacted group. ConclusionThe factors associated with impaction varies in different populations. The importance of assessment of the variables associated with impaction may facilitate to decide whether the impacted third molars have chances of eruption or need to be surgically removed to prevent unnecessary clinical problems.
