Impact of Mesioangular Mandibular Impacted 3rd Molar on Peridontal Health of Adjacent Tooth

Abstract

Objective: The aim of this study is to determine the impact of mesioangular mandibular 3rd molar impaction on periodontal health of adjacent tooth in patients. Study Design: Retrospective/observational study Place and Duration: Department of Oral & Maxillofacial Surgery, MMDC Multan, during from Oct 2020 to September 2021. Methods: Total of seventy patients of both genders was presented in this study. Detailed demographic data of enrolled cases age, sex, body mass index, symptoms and complications were recorded after taking informed written consent. All the patients had mesioangular impactions of mandibular third molars. The impaction depth, relationship with ramus, and angulation of 70 IMTMs and their association with 2nd molar distal caries and root resorption, pathological states, and closeness to the mandibular canal were assessed on panoramic radiographs. Pell and Gregory classification was used to determine position of impacted third molar. The odds ratio (OR) and 95% confidence interval (CI) of IMTM's position on the related complications (credible interval for Bayesian models). Statistical significance was defined as a two-tailed p-value 0.05. SPSS 24.0 version was used to analyze complete data. Results: There were 42 (60%) males and 28 (40%) females with mean BMI 23.13±6.46 kg/m2. Most of patients 31 (44.3%) were aged between 20-35 years. Mean attachment level was 3.03±2.34 and probing depth was 3.34±3.35. Caries, pain and swelling were the most common symptoms found among cases. Distal second molar root caries 21 (30%) and pocket formation 17(24.3%) were the most common pathologies. As per histological findings periapical inflammation was majority found in 37 (52.9%) cases followed by dental follicle in 19 (27.1%) and cyst in 11 (15.7%). Conclusion: In this study, we found that the impacted mandibular third molar was most linked with distal second molar root caries and the creation of a pocket between the impacted tooth and the second molar tooth. The most common pathology associated with the impacted molar was distal second molar root caries and the creation of a pocket between the affected tooth and the second molar.
