Incidence of Mandibular Third Molar Impaction in Patients Visiting a Private Dental College

The study aims to evaluate the incidence of types of impaction of mandibular third molars.Since mandibular third molars are the most common teeth to get impacted, it is important to know the incidence and prevalence in a particular community.The study is done using radiographic records of patients visiting the department of oral and maxillofacial surgery, with a diagnosis of an impacted third molar that has the need to undergo extraction.The sample size was of 100 patients, all above 16 years of age.The orthopantomogram and intra oral periapical radiographs of the patients were interpreted to analyze the pattern of impacted mandibular third molars.The type of impaction was determined using Winter's Classification of Impacted Teeth (1926).Based on these values the incidence of type of impaction was determined.
