Incidence of Pathologies Associated with Impacted Mandibular Premolars and Third Molars

Abstract

Impaction is the cessation of eruption or failure of a tooth to erupt caused by a physical barrier in the
eruption path, abnormal positioning of tooth and loss of space are other impediments.The rising incidence
of impacted teeth and their influence on the dental arches have long been of concern to the oral maxillofacial
surgeons.The aim of the study is to evaluate different types of Mandibular pathologies associated with
impacted third molars. This was a retrospective study conducted in the Department of Oral and Maxillofacial
Surgery in Saveetha Dental College, Chennai . A total of 470 cases ranging in the age from 18 years to 45
years with the diagnosis of Impacted mandibular third molars were considered for this study. Data were
analysed using IBM SPSS statistics.This study showed vertical impaction and mesioangular impaction were
most frequently involved in the formation of cystic lesions among which vertical impaction occupied (1.7%)
and mesioangular impaction (0.2%).Tumors with 0.6% are associated with vertical impaction of mandibular
third molar followed by mesioangular and distoangular impactions.Within the limitation of the study,we
observed that there exists a significant incidence of Pathologies associated with impacted mandibular third
molars .
