Oral Health-related quality of life after coronectomy for impacted mandibular third molar in the first postoperative week.

BACKGROUND: Coronectomy of a mandibular impacted third molar is a surgical treatment to minimize the risk for inferior alveolar nerve damage. We aimed to determine whether this procedure affected the oral health-related quality of life (OHRQoL) within the first postoperative week. MATERIAL AND METHODS: This prospective study included 50 patients that underwent a coronectomy for an impacted mandibular third molar. The patients completed the Oral Health Impact Profile-14 (OHIP-14) questionnaire and questions about pain and analgesic intake on every day during the first postoperative week. RESULTS: Mean OHIP-14 scores were highest during the first three postoperative days; the highest mean score (26.40, SD: 8.67) was observed on the first postoperative day. Mean OHIP scores gradually declined during the first postoperative week, and the mean OHIP-14 score was 9.82 (SD: 9.15) on the seventh day. Physical pain was the highest contributor to the overall OHIP-14 score. Pain gradually declined with time; the lowest mean pain score (3.38, SD: 2.2) was observed on the seventh day. OHIP-14 and pain scores were not significantly different between sexes or between different grades of impaction. OHIP-14 scores were positively correlated with pain scores. CONCLUSIONS: A mandibular third molar coronectomy had a strong effect on patient OHRQoL, particularly during the first three postoperative days.

A randomized prospective controlled trial of antibiotic prophylaxis in intraoral bone-grafting procedures: preoperative single-dose penicillin versus preoperative single-dose clindamycin.

In this comparative study, 150 consecutive patients undergoing local intraoral bone grafting randomly received either an oral single dose of 600 mg clindamycin or 2 g of the penicillin phenethicillin 1 h before incision. Primary endpoint was wound infection at the receptor site within 8 weeks of surgery. Secondary outcome measurements included postoperative infections at the donor site and adverse events as a result of antibiotic administration. Mean age of the patients was 36.8+/-12.7 years (range 18-67 years), and 98 patients were females (65.3%) and 52 males (34.7%). Infections at the receptor site were seen in 4 patients (5.3%; 95% CI 0.23-10.4%) of the phenethicillin group and in 2 patients (2.7%; 95% CI 0-6.36%) of the clindamycin group. In both groups, 3 patients had an infection at the donor site. Postoperative infections were predominantly caused by alpha-haemolytic Streptococci sensitive to penicillin. No significant difference was found between prophylactic single doses of phenethicillin and clindamycin with regard to postoperative infection in patients undergoing local bone augmentation procedures.
