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.
