Correlation of antibiotic prophylaxis and difficulty of extraction with postoperative inflammatory complications in the lower third molar surgery

초록

Our aim was to investigate the correlation among antibiotic prophylaxis, difficulty of extraction, and postoperative complications in the removal of lower 3rd molars. A total of 1222 such extractions in 890 patients between January 2010 and January 2012 were analysed retrospectively. The difficulty of extraction measured by Pederson's index, antibiotic prophylaxis with cefditoren, and postoperative complications were recorded. The difficulty of extraction was significantly associated with postoperative complications (p = 0.03). There were no significant associations between antibiotic prophylaxis and postoperative complications in groups of equal difficulty ("easy" group (class I) p = 1.00; "moderate" group (class II) p = 1.00; and "difficult" group (class III) p = 0.65). There was a small but insignificant increase in the number of dry sockets and infections in class III cases. In conclusion, this study provides further evidence that antibiotic prophylaxis for the prevention of postoperative inflammatory complications is unnecessary for extraction of 3rd molars.
