RADIOGRAPHIC EVALUATION OF IMPACTED MANDIBULAR THIRD MOLARS AND SOME ASSOCIATED PATHOSES
Main Article Content
Abstract
Background: Impacted mandibular third molar (IM3M) has long been a prevalent condition associated with a wide range of relevant pathoses. A panoramic radiograph is a plain film that is particularly valuable for screening of mandibular third molar region. Objectives: To determine the frequency of different IM3M positions and angulations based on panoramic radiographs and the associated pathoses on both panoramic radiographs and clinical assessment. Materials and method: A descriptive cross-sectional study on 174 IM3Ms using Pell & Gregory’s and modified Winter's classifications. The associated pathoses were assessed clinically and radiographically with panoramic images of patients at Can Tho University of Medicine and Pharmacy Hospital. Results: Out of 174 patients with 174 IM3Ms, the proportions of males and females were 39.7% and 60.3%. respectively. The most common type of third molar space was class II (62.6%). 49.4% of samples were found at level A. Mesioangular impaction accounted for the largest proportion of the total (41.4%). Clinically, the most common disease associated with IM3M was distal caries of mandibular second molars (19.5%), whereas panoramic radiographs saw the highest percentage for distal bone resorption of second molars (66.1%). Conclusion: IM3Ms were found at various positions and angulations, which are associated with several pathological conditions. Clinical assessment combined with panoramic radiographs can provide physicians with essential information for diagnosis, treatment planning, and prevention. Keywords: Impacted tooth, third molar, classification, panoramic.
