FREQUENCY & PATTERN OF MANDIBULAR THIRD MOLAR IMPACTIONS. A CROSS SECTIONAL STUDY
The aim of the study was to evaluate the mandibular third molar incidence, position and depth in mandibular bone in order to plan and manage patients efficiently based on panoramic radiographs and clinical findings found at Foundation University College of Dentistry, Islamabad. A cross-sectional study was conducted from January 2019 to December 2019. It was done in the Department of Oral Medicine, Foundation University College of Dentistry Islamabad. Total of 160 patients with 258 impactions, were included in the study. Details were compiled regarding patient’s age, gender, frequency of impacted mandibular third molars, angulation of impacted teeth, level of impaction, relationship of mandibular third molar with ramus of the mandible and pathologies associated with these teeth and relationship of inferior alveolar nerve in association with the impacted tooth. SPSS software version 2019 was used to analyze our data. Females (57.5%) presented with more impactions than males (42.5%). Mesioangular impactions (51.16%) were most commonly seen, followed by vertical impactions (19.37%) and most common pathology associated was pericoronitis (16.9%). Mandibular third molar impaction is the paramount procedure being carried out in oral and maxillofacial surgery department at FUCD. Early diagnosis with proper radiographic interpretation by orthopanomogram leads not only to the knowledge of proper position and depth of impaction but also to proper prognostic outcomes afterwards.
