Abstract

Objectives: Analyzing the correlation between clinical characteristics and morphology of mandibular wisdom teeth (MWT) on Conebeam CT. Subjects and methods: The study subjects were patients with MWT causing complications who came for examination and treatment at the Dental and Maxillofacial Clinic, Department of Stomatology, University of Medicine and Pharmacy - Hanoi National University, in accordance with the selection criteria. and exclusion criteria. Research method is a cross-sectional descriptive study, sample size is 98 patients corresponding to 98 CBCT films with full images of 152 MWT. Results: Wisdom teeth misaligned 80 - 100 degrees are 0.21 times less likely to cause decay on the distal surface of tooth 7. Wisdom teeth with an inclination of 11-79 degrees are 0.42 times less likely to have decay. Fully erupted teeth have a 2.39 times higher risk of tooth decay. Withholding food increases the risk of inflammation around the crown of the wisdom tooth by 12.21 times. Wisdom teeth in position B are 0.43 times less likely to have inflammation around the crown of the wisdom tooth. Patients who come to the doctor for the reason of pain are less likely to have pain. The risk of causing alveolar bone loss is more than 0.17 times. Conclusion: In our study, there was a statistically significant relationship between the MWT axis relationship compared to R7 and complications of R7 far facial caries and MWT caries. Wisdom tooth eruption is also associated with complications of MWT. Inflammatory complications around the MWT body and the MWT boss are related to the patient's reason for examination as well as the MWT depth compared to the R7 occlusal plane.
