The effect of several pre- and per-operative variables on indicators of postoperative morbidity was assessed in 204 patients after unilateral mandibular third-molar surgery. The variables included gender, age, use of tobacco and alcohol, state of eruption, depth and angulation of the tooth, duration of the operation, pericoronitis, and time of day of surgery. Visual analogue scales were used for patient assessment of pain and swelling and for clinical assessment of swelling. Maximum pain was indicated 6 h postoperatively and maximum swelling the first postoperative evening. The results showed a mean reduction of mouth opening capacity (trismus) of 31% the 1st postoperative day. Mean analgesic consumption was 3.7 tablets, mean number of days of inability to work 1.1, and the rate of postoperative alveolitis 1.9%. The variation of the morbidity indicators was considerable. Multiple classification analyses showed that the predictors explained from 17% (clinically assessed swelling) to 8% (pain 6 h postoperatively) of the variance of these indicators. It is concluded that these commonly used predictors only to a minor extent can explain the wide variation in postoperative morbidity after mandibular third-molar surgery.
在204例单侧下颌第三磨牙手术后的患者中，评估了几个术前和术中变量对术后发病指标的影响。这些变量包括性别、年龄、烟草和酒精使用情况、萌出状态、牙齿的深度和角度、手术持续时间、冠周炎以及手术时间。采用视觉模拟量表对患者的疼痛和肿胀进行评估，并对肿胀进行临床评估。术后6小时出现最大疼痛，术后第一个晚上出现最大肿胀。结果显示，术后第1天平均开口能力（牙关紧闭）降低31%。平均镇痛药消耗量为3.7片，平均无法工作天数为1.1天，术后牙槽炎发生率为1.9%。发病指标的变化相当大。多重分类分析表明，这些预测因素可解释这些指标方差的17%（临床评估肿胀）至8%（术后6小时疼痛）。得出的结论是，这些常用的预测因素只能在很小程度上解释下颌第三磨牙手术后术后发病率的广泛差异。
