Abstract

Background: The purpose of this study is to determine the angulation of mandibular third molarin orthodontic cases which are planned for extraction and non extraction. Methods: This is across-sectional descriptive study in which pre-treatment panoramic radiographs of 49 patients, agerange 11–26 years were taken from the OPD of Department of Orthodontics, Dr. Ishrat- ul -EbadKhan Institute of Oral and Health Sciences (DIKIOHS), Dow University of Health Sciences. Theangles between the long axis of the second and third molars were measured. Descriptive statisticswere applied. Mann-Whitney U-test was used for intergroup comparison extraction and nonextraction cases. Results: This study consists of 49 patients with mean age of 17.94 years. Overall result concluded that mandibular third molar angulations were from 8–94º in extraction casesand 10–73º in non extraction cases. However, the pre-treatment 3rd molar angulation differences inextraction and non extraction cases were statistically insignificant with p-value >0.05.Conclusions: This study evaluates third molar angulations in pre-treatment cases, the differencesin angulation were like other morphological differences but changes in angulation after treatmentmay or may not be related to extractions.Keywords: Third molar angulation, extraction and non extraction orthodontic cases
