FREQUENCY OF MESIOANGULAR IMPACTED MANDIBULAR THIRD MOLAR AND COMMON PATHOLOGIES ASSOCIATED WITH IT
Mandibular third molars being the last tooth to erupt frequently become impacted due to lack of space, hard and soft tissue obstruction and aberrant path of eruption. Mesial angulation of impacted mandibular molars is more common than other angulations. Impacted teeth can be associated with various pathologies like pericoronitis, caries, periodontal problems, root resorption and cyst and tumors. The study aims to determine the frequency of mesioangular impaction in the local population and common pathologies associated with it. This descriptive study was conducted in the department of Oral and Maxillofacial Surgery at Khyber Medical University-Institute of Dental Sciences, Kohat, from November 2017 to august 2018. A total of 410 patients, aged 18 years and above, presenting with impacted mandibular third molars were included in this study. The angulations and associated pathologies were evaluated by history, clinical and radiographic examination. Impacted teeth were more common in males (60.2%) aged 25 years and below (58.8%). The most frequent angulation was mesioangular (51%) and the common pathology associated with these mesioangular impactions was pericoronitis followed by carries. Frequency of cyst and tumors accounted for only 1 percent which does not support the prophylactic extraction of asymptomatic impacted teeth to prevent these pathologies.
