Any tooth may become impacted but the most common are mandibular third molars The tooth may become impacted because of adjacent teeth, dense overlying bone or soft tissue, lack of space in the jaw, aberrant path of eruption, abnormal positioning of tooth bud or pathological lesions etc. Information on the impacted mandibular third molar etiology, clinical anatomy, radiologic examination, surgical treatment, possible complications and pathological condition associated with it, is important for dentist. Aim and Objectives: The aim of study was to determine the prevalence and pattern of impacted third molars in Bareilly population with objectives to estimate the frequency of impacted third molars and to evaluate the association of impacted third molars with other pathological conditions.
