Background & aim:The mandibular third molar is the most common impacted tooth, and there are many statistical inconsistencies in the rate of caries caused by impacted third molars in second molars. Therefore, the aim of the present study was to determine and investigate the effect of impacted mandibular third molars on caries and the prevalence of pathologies of the distal surface of second molars in panoramic radiographs.
Methods: In this descriptive-analytical study conducted in 2023, panoramic radiographs of individuals were divided into two groups. The first group included patients with impacted mandibular third molars and the second group included patients with erupted mandibular third molars. The angle of impaction of the impacted third molars and the prevalence of caries and distal surface pathologies (bone resorption, pericronitis, root resorption, cysts) of the second molars were determined in both groups. The collected data were analyzed using the chi-square test.
Results: In this study, the highest incidence of mesiangular impaction was 57.9%. There was a significant relationship between impaction angle and pericronitis (p<0.0001) and the effect size was high, but there was no significant relationship between impaction angle and other dental complications (bone resorption, root resorption, cyst).
Conclusion: Impaction of the mandibular third molar had a significant effect on increasing bone loss and pericronitis, but it did not indicate a significant association with caries, root resorption, and cysts in the adjacent second molar. The vertical angle of impaction was most associated with pericronitis, and male gender was likewise associated with an increased risk of bone loss and horizontal angle of impaction. Therefore, the decision to preventively extract or periodically care for these teeth should be based on a careful assessment of these risk factors.
