History

Impacted third molar removal is one of the common minor oral surgical procedures performed in routine dental practice. In human history, the earliest recorded case of impaction was discovered in the mandible of girl who lived in the Magdalenian cultural period. Tooth is considered impacted when its eruption into normal functional occlusion has been interfered with teeth, overlying bone, or soft tissue and it is not fully erupted by its expected age of approximately 20 years.A retrospective cohort study was conducted by taking the first 1000 orthopantamogram (OPG) from the Department of Oral Medicine and Radiology, rama dental college , hospital and Research from August 2021 to December 2022 aged between 20 and 40 years From this study, we concluded that third molar impactions have a mandibular predominance, males have increased predilection of third molar impaction than females and were equally common on both sidesand mesioangular impaction occurs more commonly followed by vertical impaction. The most common pattern of impaction was Level A and Class II.
