Aim: The aim of this retrospective study is to assess the demographic details, mode of extraction, and prevalence of dry socket in patients with mandibular third molar extraction. Materials and methods: Patients who had undergone mandibular third molar (impacted/nonimpacted) extraction were included in this study. The case sheets were obtained from Saveetha Dental College and Hospitals. The information retrieved from the Saveetha Dental College and Hospitals dental information archiving software (DIAS) system included patient's age, gender, systemic disease (diabetes), teeth no. and the mode of extraction of teeth (transalveolar, surgical extraction of impacted teeth, extraction), and the postoperative complications (dry socket) associated. The data included for this study were from June 2019 to March 2020 and tabulated. The statistical test was carried out through SPSS and the Pearson's Chi-square test was performed. Results: Total 691 patients who had undergone mandibular third molar extraction during June 2019 to March 2020 were included in this study. Out of 691 patients, 53.91% were males and 46.09% were females. The higher prevalence of age groups of 26–35 (36.06%) was noted. Total 94.5% of the patients were diabetic and 5.5% were nondiabetic. The most number of treatments done is through surgical extraction of impacted teeth (surgical exposure of flap and tooth) (48.48%), followed by extraction (forceps extraction) (42.55%) and transalveolar extraction (removing section of tooth, open sectioning) (8.97%). The prevalence of dry socket was 4.05%, and 95.95% of the patients did not experience dry socket. There was higher prevalence of dry socket in nondiabetic patients (3.62%) than diabetic patients (0.43%). Conclusion: The dry socket was most commonly associated with males and during normal extraction (i.e., without surgical exposure of flap and tooth). The dry socket remains as the common postoperative complication. Clinical significance: The study observed that the extraction (through forceps) procedure leads to an increased incidence of dry socket. Hence, this signifies the importance of postoperative instructions to be followed irrespective of the type of extraction.
