Place and Duration: Oral & Maxillofacial Surgery Department of Dr Ishrat ul Ebad Khan Institute of Oral Health Sciences, Karachi for the duration of four months from 1^st November, 2019 to 29^th February, 2020.

Material and Methods: Total 650 patients of both genders with ages 8-60years were included in this study. 1000 teeth were extracted from enrolled patients. Patients detailed demographics including age, sex, residence and co-morbidities were recorded after taking written consent. Qualitative data like gender, reason of extraction of tooth, tooth loss pattern and socioeconomic status were presented as frequencies and percentages. Data was analyzed by SPSS 24.0.

Results: Out of 650 patients 260 (40%) were male while 390 (60%) were females with mean age 36.42±11.54 years. Mean BMI of the patients were 21.38±2.52. We found that the majority of the patients 495(76.15%) had lower socioeconomic status while rest of the patients belong to middle socio economic status. In extraction of tooth the main etiology was caries 700(70%) which was followed by periodontal diseases 135(13.5%) and impaction was in 115(11.5%) tooth. This provided results that the ratio of third molar 260(26%) was greater than that of first molar tooth 210(21%).

Conclusion: In this study we concluded that the caries followed by periodontal diseases was the major causes of tooth extraction and majority of the patients were from the lower socioeconomic status.
