Association between Mandibular Third Molar Impaction Patterns and Pathologies of the Adjacent Second Molar among a Sample of Yemeni Adults: A Radiographic Cross-Sectional Study
##plugins.themes.bootstrap3.article.main##
Abstract
Background: Impacted mandibular third molars are prevalent and can result in a number of pathologic conditions of adjoining mandibular second molars, such as distal caries, periodontal bone loss, and root resorption. It is important to know the pattern of impaction and risks involved in its early diagnosis and prophylaxis.
Objective: The aim of the study was to evaluate the connection between the impaction of the mandibular third molars and the pathological alteration of second molars in the Yemeni adults.
Methods: The study was a cross-sectional radiographic study of 250 panoramic radiographs from private dental clinics and image centers in Taiz, Ibb, and Sana in Yemen. Angulation (Winter classification), depth (Pell and Gregory), and related pathologies of the second molars of the impacted mandibular third molars were examined in 320 cases. Analysis of data was done through descriptive statistics and Chi-square tests.
Results: Of the 761 participants (mean age 24.8±4.2 years), most lived in cities and were either fifth-year students or interns. A substantial correlation (p < 0.05) was found between the participants' feelings towards artificial intelligence (AI), their degree of university education, and their interaction with online social networks. Levels of AI expertise varied among regions. Scores were significantly higher for participants residing in Sana'a and outside of Yemen compared to those from other locations (p=0.012). None of the other demographic variables significantly altered these outcomes.
Conclusion: Mesioangular and deeper impactions are strongly correlated with increased risk of second molar caries, alveolar bone loss, and root resorption. These complications can be minimized through early radiographic assessment and early intervention.
