The purpose of the retrospective study was to evaluate pain and discomfort related to surgical exposure according to initial localization of impacted maxillary canines.
Pre-treatment cone-beam computed tomography (CBCT) data and discomfort evaluation questionnaire of 25 patients (17 female, 8 male), treated with combined surgical-orthodontic approach was analysed. The questions included: level of discomfort during surgery (0 to 10), level of pain (0 to 10) in the evening, one, two days and a week after surgery. CBCT analysis consisted of evaluation of impacted maxillary canines mesiodistal inclination, horizontal, vertical dislocation from alveolar process edge, labiopalatal localization and length of eruption path. To carry out research objectives a Spearman and interclass correlation coefficients, Mann-Whitney U test, Cohen's kappa coefficient were used. Level of significance was 0.05.
Average level of discomfort during the procedure was 2.8 (SD 2.3). Pain level the evening after the surgery was the highest - 3.3 (SD 2.1) and decreased over the week. Pain level differed significantly between different days (P < 0.001). Neither labial or palatal location nor the unilateral or bilateral impaction had effect on the level of pain (P > 0.05). The results showed that pain during different stages of measuring as well as level of discomfort during surgical exposure did not differ statistically significantly depending on severity of impaction (P > 0.05).
There was no significant relation between the discomfort and the location of the impacted canine. Patient's gender or age did not have an impact on discomfort and pain.
本回顾性研究的目的是根据上颌阻生尖牙的初始位置评估与手术暴露相关的疼痛和不适。
分析了25例接受外科正畸联合治疗患者（17例女性，8例男性）的治疗前锥形束计算机断层扫描（CBCT）数据和不适评估问卷。问题包括：手术期间的不适程度（0至10分）、术后当晚、术后1天、2天和1周的疼痛程度（0至10分）。CBCT分析包括评估上颌阻生尖牙的近远中倾斜度、水平和垂直方向与牙槽突边缘的错位、唇腭侧位置以及萌出路径的长度。为实现研究目标，使用了Spearman和组内相关系数、Mann-Whitney U检验、Cohen's kappa系数。显著性水平为0.05。
手术过程中的平均不适程度为2.8（标准差2.3）。术后当晚的疼痛程度最高，为3.3（标准差2.1），并在一周内逐渐减轻。不同日期的疼痛程度差异显著（P<0.001）。唇侧或腭侧位置以及单侧或双侧阻生均对疼痛程度无影响（P>0.05）。结果表明，根据阻生严重程度，测量不同阶段的疼痛以及手术暴露期间的不适程度在统计学上无显著差异（P>0.05）。
不适与阻生尖牙的位置之间无显著关系。患者的性别或年龄对不适和疼痛无影响。
