Pak Oral Dental J Jan ;39(1):43-6.

The aim of the study was to determine the role of preoperative antibiotics in prevention of postoperative infection among patients undergoing impacted mandibular third molar surgery. A randomized controlled study was conducted at the Department of Oral and Maxillofacial Surgery, de’Montmorency College of Dentistry/ Punjab Dental Hospital, Lahore from January 2018 to June 2018. A total of one hundred fifty patients, randomized into two equal groups A and B by using lottery method, having impacted mandibular third molar of similar difficulty index were operated for surgical extraction. Group A (without antibiotic cover) did not receive prophylactic antibiotic cover, whereas group B (with antibiotic cover) received preoperative antibiotics, 2 gram amoxicillin capsule one hour prior to surgical intervention. Data concerning patient’s demographics, preoperative antibiotics and status of postoperative infection was obtained and analyzed. Among 150 patients, 58(38.7%) were males and 92(61.3%) were females with average age of 25.36±5.01 years. The infection rate in group A was 28.0% as compared to 6.7% in group B, and the difference was highly significant statistically with p-value 0.001. The results of this study confirmed that a preoperative antibiotic reduces the chances of postoperative infection in impacted third molar surgery.
