ABSTRACT

Objective: Surgical exodontia of an impacted mandibular third molar may influence the periodontal outcome of the adjacent second molar. There is lack of consensus among the dentists and the oral surgeons concerning the effect of surgical extraction of an impacted molar on periodontal health of the adjacent second molar. The purpose of this study was to examine the postoperative periodontal outcome of the mandibular second molar following surgical extraction of an impacted mandibular third molar. Materials and Methods: A prospective cohort study was designed. The convenience sampling method was used to obtain a sample size of eighty. All the participants had a mesioangularly impacted mandibular third molar. The mean age of the participants was 28.1 years. To assess the impact of surgical extraction on the periodontal health of the adjacent molar, the probing depth (PD) and the attachment level (AL) were used as the primary outcomes. They were measured at baseline and at three months after the surgery. A total of sixty-nine patients completed the study. Data were analyzed using the Paired-Sample t-test and Repeated measures ANOVA at a significance level of 5% in SPSS Version 21 Software. Results: The analysis of the data showed a statistically significant decrease in PD (p<0.001) and improvement in AL (p<0.001) on the distal aspect of mandibular second molar following three months after the surgery. Conclusion: The results of our study demonstrate that surgical exodontia of impacted mandibular third molar improves the primary outcome of the periodontal tissues on the distal aspect of the adjacent second molar.
