Abstract

Introduction: The incidence of impacted mandibular third molars varies between different populations, and their removal remains a controversial issue. According to National Institute of Clinical experience (NICE) guidelines , well defined criteria for removal of third molar were unrestorable caries , periapical pathologies , infection , disease of the follicle , cyst or tumors. The outcomes of this research will offer significant insights to dental practitioners and individuals about the possible advantages and drawbacks of retaining or extracting impacted lower third molars
Materials And Methods: In this retrospective study, 11,000 panoramic radiographs of patients who visited Saveetha dental college between December 2020 and January 2022 were analyzed. The study focused on radiographic lesions associated with impacted mandibular third molars, including caries in the third molar and adjacent tooth, pericoronal and periapical radiolucencies around impacted lower third molars, and odontomes. The exclusion criteria included patients under 20 years of age, those with a history of pathology or trauma, and syndromic patients.
Results: Among 11,000 panoramic radiographs evaluated, 14,847 impacted mandibular third molars were found. The prevalence of pathologies associated with mandibular third molars were caries (46.5%), pericoronal radiolucencies (32.7%), periapical radiolucencies (12.6%), cyst and tumors (6.9%).The study also found that the prevalence of pathologies associated with mandibular third molars increased with age, and males were more affected than females.


Conclusion: In conclusion, this study provides valuable information on the prevalence of pathologies associated with lower third molars, which can aid in decision-making regarding the management of impacted third molars. Additionally, the results highlight the importance of regular dental check-ups and radiographic examinations to monitor the development of pathologies associated with mandibular third molars.Hence, based on the high incidence of pathology related to mandibular third molars, prophylactic extraction can be considered as a viable option.
