Complications Associated with The Occurrence of Impacted Mandibular Third Molars in Saudi Arabian Sub-Population: Najran Province Experience| Biomed Grid

Introduction: Impacted third molars impaction is a global clinical condition that is rising. Literature is still lacking on the reported cases of associated pathologies with impacted mandibular third molars despite its richness in prevalence and its surgical removal. Materials and Methods: This is a retrospective study with data such as gender and age of patients, special relationships of the impacted molars, reason for extraction, tooth extracted and associated pathologies collected from the Department of Oral and Maxillofacial Surgery, Najran Specialty Regional Dental Center, Najran Kingdom of Saudi Arabia from 2015-2018. The data were processed and analyzed using IBM SPSS software version 25 for IOS (Armonk, NY: IBM Corp). Results: A total of 1024 mandibular third molar extractions was carried out during the study period from 609 (59.5%) females and 415 (40.5%) males (F:M = 1.5:1) (1). Out of this number, 570 (55.7%) had associated pathology with 270 (47.4%) males and 300 (52.6%) females and prevalence rate of 55.7%. The age ranged from 17 to 69 years (mean ± SD, 31.4 ± 9.6years) with majority in the age group (21-30) years. Distal caries on the second molar tooth accounted for the highest number of associated pathologies 193 (18.8%) followed closely by pocket alone between the second and third molars 157 (15.3%). Conclusion: Distal second molar root caries and pocket formation between the impacted tooth and second molar tooth was the most associated pathology with the impacted molar in the current study. These were frequently associated with a mesio-angular impaction
