Introduction: Third molar impaction is a common condition associated with a high standard of living. Aim: The main objective of the study was to document the prevalence of mandibular third molar impactions among the Najran populace. Materials and Methods: This is a retrospective study reviewing computerized medical records and panoramic radiographs of patients presenting for the extraction of mandibular third molars. Ethical approval was granted from the General Directorate of Health Affairs, Ministry of Health, Najran region. Data such as demographics, indications for third molar removal, position, and pattern of third molar impaction were collected. Data were stored and analyzed using IBM SPSS software version 25 for IOS (Armonk, NY: IBM Corp). Results and Discussion: Amongst 6205 extractions, 1024 mandibular third molar extractions were carried out with a prevalence rate of 16.5%. There were 609 (59.5%) female and 415 (40.5%) male (F:M = 1.5:1). The age ranged from 17 to 69 years (mean ± standard deviation, 31.4 ± 9.6 years), with the majority (52.1%) in the age group of 21–30 years. One hundred and ninety-one (18.6%) of the pericoronitis cases were associated with vertical impaction, while the majority of the caries were associated with mesioangular impaction (323 [31.5%]). Mesio-angular impactions (40.8%) and Level A depth (477 [46.6%]) were the most common. Class I ramus relationship had the highest distribution (561 [54.8%]). Conclusion: We have reported a prevalence rate of 16.5% of impacted mandibular third molar in mostly 21–30 years of age with female preponderance. Pericoronitis was the main indication for surgical extraction.

Introduction: Tooth loss is a worldwide public health concern of huge proportion. Problems associated with permanent tooth loss are enormous. Aim: This study aims to investigate the major reasons and patterns of permanent tooth extraction in a government referral dental center. Materials and Methods: This retrospective study was conducted on patients who had intra-alveolar extraction of teeth in our facility between January 2016 and December 2020. Sociodemographic data and type of tooth extracted were recorded. Reasons for extraction were classified into the following: caries, failed root canal treatment, failed restoration, periodontitis, prosthodontic, orthodontic, trauma, and over-eruption. Data were stored and analyzed with SPSS for MOS, Version 20.0. Results and Discussion: A total of 8065 (3248, 0.3%) males and 4817 (59.3%, females) patients presented for teeth extraction during the study period with 11,746 extractions done, giving an average of 1.5 extractions per individual. The age range of 11–102 years with a mean (±standard deviation) of 36.0 (16.6) was observed. The majority of the patients were in the age groups of 21–30 years (1992 (24.7%), then 31–40 years (1773 (22.0%). Caries and its sequelae accounted for the main reasons for tooth mortality. In the mandible, a total of 5321 (45.3%), while in the maxilla, a total of 6425 (54.7%) teeth were extracted. Molars were the most extracted tooth in both jaws (3485 (29.7%)) Conclusions: The current study found that dental caries, and its sequelae, was the main reason for tooth extraction in a Saudi subpopulation, Najran. Molars were the most commonly extracted teeth.
