The records of 1087 patients who underwent surgical removal of third molar teeth were prospectively examined to analyse the possible relationship between postoperative complications and the surgeon's experience parameter.
Seven surgeons (three specialists in surgical dentistry [specialists SD] and four oral and maxillofacial Senior House Officers [OMFS residents]) carried out the surgical procedures. For each patient, several variables were recorded including age, gender, radiographic position of extracted teeth, treating surgeon, duration of surgery and postoperative complications.
Analysis of the data revealed some differences in the incidence of complications produced by the specialists SD and OMFS residents. The main statistically relevant differences were increase the incidences of trismus, nerve paraesthesia, alveolar osteitis and infection in the resident-treated group, while the specialist-treated group showed higher rates of post-operative bleeding.
The higher rate of postoperative complications in the resident-treated group suggests that at least some of the complications might be related to surgical experience. Further work needs to compare specialists of training programmes with different years of experience, using large cross - sectional studies.
对1087例行第三磨牙拔除术患者的记录进行前瞻性检查，以分析术后并发症与外科医生经验参数之间的可能关系。
七名外科医生（三名口腔外科专科医生[SD专科医生]和四名口腔颌面外科高级住院医师[口腔颌面外科住院医师]）实施手术操作。对每位患者记录了几个变量，包括年龄、性别、拔除牙齿的影像学位置、主治医生、手术时间和术后并发症。
数据分析显示，SD专科医生和口腔颌面外科住院医师引发并发症的发生率存在一些差异。主要的统计学相关差异是，住院医师治疗组的牙关紧闭、神经感觉异常、干槽症和感染发生率增加，而专科医生治疗组的术后出血率较高。
住院医师治疗组较高的术后并发症发生率表明，至少部分并发症可能与手术经验有关。需要进一步开展工作，通过大型横断面研究，比较不同经验年限培训项目的专科医生。
