Swelling, pain and trismus were evaluated quantitatively after the removal of impacted mandibular third molars on 30 healthy individuals. Evaluation took place 48 h and 7 days after surgery. The mutual correlation between the complaints was determined as well as the correlation between the length of the operation and the degree of postoperative complaints. It is concluded from the study that the longer the operation takes, the more postoperative pain can be expected. However, neither swelling nor trismus is correlated with the length of time of the operation. The size of the swelling was not related to the degree of trismus or postoperative pain. A strong interrelation between postoperative pain and trismus indicates pain as the main reason for reduced mouth opening after removal of impacted mandibular third molars.
对30名健康个体拔除下颌阻生第三磨牙后，对肿胀、疼痛和牙关紧闭进行了定量评估。评估在术后48小时和7天进行。确定了各项症状之间的相互关系以及手术时长与术后症状程度之间的相关性。该研究得出结论，手术时间越长，术后疼痛预期越严重。然而，肿胀和牙关紧闭均与手术时长无关。肿胀程度与牙关紧闭程度或术后疼痛无关。术后疼痛与牙关紧闭之间存在密切关联，表明疼痛是拔除下颌阻生第三磨牙后张口受限的主要原因。
