Risk Factors In Complication Of Wound Healing After Third Molar Surgery

Third molar surgery is the most common procedure done in dentistry. Although the overall complication rate is low, it is essential to prevent them. Factors reported to be associated with complication included age, gender, medication and periodontitis etc. The aim of the study was to evaluate the prevalence of complication post extraction of third molar surgery and to discuss the risk factors. This was a descriptive study which was performed in a university setting where the required data of patients who were diagnosed for third molar surgery in the department of oral and maxillofacial surgery at a private teaching hospital, Chennai from June 2019 to March 2020, was collected by reviewing patients records and the analysis of data of 86000 patients. The collected data was cross verified using photographs, reviewed by a reviewing expert and tabulated in Microsoft excel . The Sample size of the total number of patients treated for third molar surgery was n=529. The tabulated data was imported to SPSS software ( statistical package for social studies ) version 22.0 ( IBM corporation ) for statistical analysis. To minimize sampling bias, collection of data was done by simple random sampling methods within the university. There is high internal validity and low external validity. Incomplete , censored and repeated data were excluded from the study. Association between Gender, Age distribution, Extraction site and outcome of the third molar extraction was done. Chi square test was also done for evaluating the statistical significance. From this study, 4.9% of the patients had complication post extraction. There was a higher rate of complication among females (3.2%) than females (1.7%), among 31-50 years showed a higher rate of complication (1.32%) than the rest. Complications were most commonly seen in mandibular third molars than maxillary third molars. This is the first study to assess the complication rates of third molar surgery done by undergraduate students. From this study we can conclude that there were fewer complications reported after third molar surgery done by undergraduate students
