Oral Health-related quality of life after coronectomy for impacted mandibular third molar in the first postoperative week / Calidad de vida relacionada con la salud bucal después de la coronectomía para el tercer molar mandibular impactado en la primera semana postoperatoria

ABSTRACT

Background: Coronectomy of a mandibular impacted third molar is a surgical treatment to minimize the risk forinferior alveolar nerve damage. We aimed to determine whether this procedure affected the oral health-relatedquality of life (OHRQoL) within the first postoperative week.Material and Methods: This prospective study included 50 patients that underwent a coronectomy for an impactedmandibular third molar. The patients completed the Oral Health Impact Profile-14 (OHIP-14) questionnaire andquestions 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 thefirst postoperative week, and the mean OHIP-14 score was 9.82 (SD: 9.15) on the seventh day. Physical pain wasthe highest contributor to the overall OHIP-14 score. Pain gradually declined with time; the lowest mean painscore (3.38, SD: 2.2) was observed on the seventh day. OHIP-14 and pain scores were not significantly different be-tween 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 duringthe first three postoperative days.(AU)
