Abstract
Objective:To investigate the influence of surgical difficulty on postoperative pain and trismus after extraction of mandibular third molars.Method:A prospective study was performed of 244 patients who underwent mandibular third molar extractions. For evaluation of surgical difficulty,a 4-class scale was completed after surgery:I:extraction with forceps and elevator;II:extraction requiring coronal section;III:extraction requiring flap operation, osteotomy and coronal section;IV:complex extraction(root section). the operation time was record,postoperative 6 d,the level of pain was record every day by the method of visual analogue scale(VAS),and the MID was record too. Result:Mean pain evaluation was significantly higher in difficulty classⅢand IV than in difficulty class I on days 0 to 6 inclusive(P<0.05),and significantly higher in class II than class I on days 0 to5 inclusive(P<0.05). MID on day 0 to 6 in the class I was the biggest,there was no significantly difference compared with preoperative,but the differences were significantly compared with other classes(P<0.05). MID of class II,III,IV were significantly decreased after 3 days. Patients need a painkiller in classⅠwithin 24 h after surgery were lower than that of classⅡ,Ⅲ,Ⅳ. Conclusion:Mandibular third molar removal surgery,surgery more difficult and complex,tooth,the longer the more serious the postoperative pain and limited mouth opening.关键词
