Association of Impacted Mandibular Third Molar with Caries on Distal Surface of Second Molar

Objectives: To evaluate impacted mandibular third molar tooth region and obtain linear measurements using CBCT images and to assess the relationship between the impacted third molar and the mandibular canal. Methods: CBCT scans of 351 patients (208 females, 143 males) were assessed. Age, gender, and impaction site were recorded for each patient. The relationship of third molars with the vertical axis of second molars, 2nd molar resorption and the relationship between third molar apices and the mandibular canal were assessed. In addition, the distance between ramus and second molar, mesiodistal width of the third molar, the angle between third molar and second molar, and width of the third molar capsule were measured. Binary Logistic Regression, Chi-Square Test, and General Linear Model were used for statistical analysis. Results: The highest percentage of impaction was found for mesioangular followed by transversal and vertical. The transversal impacted third molars revealed a significant association with adjacent second molar root resorption (p<0.001). There was a statistical significance between the second molar resorption and distance between ramus and second molar (p<0.001). The mesioangular impacted third molars revealed significant relation with the mandibular canal (p<0.05). The most frequent variation found was the dental canal followed by the retromolar canal. In general, higher measurement values were obtained for men when compared to women (p<0.05). Conclusion: CBCT assessment of the third molar region provided useful information regarding impacted mandibular third molar surgery operations.

The Impact

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.

And Control

Despite the frequent discussion of complications associated with surgical removal of wisdom teeth in the scientific literature, increased mobility of the second molar, which can affect the clinical status of the pulp, is often downplayed or overlooked. This study aimed to evaluate surgical removal of an impacted third molar on the change in the electrosensitivity of the pulp of the mandibular second molar. Sixty patients consecutively presenting to the Department of Oral Surgery to remove an impacted mandibular third molar were included in the study. Clinical examinations of pulp sensitivity of second molars in both the study and control groups were evaluated before the procedure, seven days after the procedure, and eight weeks after the procedure. The surgical removal of an impacted mandibular third molar significantly affected the pulp sensitivity of the second molar.
