Abstract: Introduction: Surgical removal of mandibular third molars is one of the most frequently performed procedures in oral and maxillofacial surgery. Aims and objectives: The main objective of the study is to analyze the role of preoperative antibiotics in prevention of postoperative infection after impacted mandibular third molar surgery. Material and methods: This cross sectional study was conducted in THQ Hospital, Tandlianwala during September 2018 to November 2018. The data was collected from 80 patients who undergo mandibular third molar surgery. The data was divided into two groups according to the use of antibiotics. Group 1 of the patients used Amoxycillin 500 mg thrice daily for 5 days and Tab Metronidazole 400 mg thrice daily for 5 days after the surgical removal of mandibular third molars. But second group was considered as a control group and treated with no antibiotic. However, both the groups were prescribed anti-inflammatory drugs and analgesics. Results: The data was collected from 80 patients, divided into two groups. According to results there was a significance decrease in pain by using antibiotics with a p-value of <0.001 which was highly significant. No statistically significant difference was seen in interincisal distance between the groups on the 2nd, 5th, 7th and 10th postoperative days. On the 2nd postoperative day, all the patients of group I had swellings, whereas 78% of patients of group II had swellings, with a p-value <0.001 which was highly significant. Conclusion: It is concluded that no difference was found between patients who received postoperative antibiotics and the control group, in incidence of postoperative treatment.
