The aim of the present study was to compare the incidence of postoperative pain in single sitting root canal treatment after using two reciprocating and two continuous rotating file systems.
One hundred and four permanent mandibular canine and first premolar teeth were selected for the study and were divided into two groups 1 and 2 comprising 52 teeth each. Group 1 was treated using reciprocating file systems and was subdivided into two subgroups A and B using WaveOne Gold (WOG) and Reciproc Blue (RB), respectively. Group 2 was treated using continuous rotating file systems and was divided into two subgroups A and B using One Curve (OC) and Vortex Blue (VB), respectively. Treatments were performed in a single sitting. After the visit, the patients were given a prescription for ibuprofen 400 mg to be taken every 6 h if they experience pain. Participants were asked to rate the intensity of the postoperative pain on a visual analog scale according to four classes (no pain, mild pain, moderate pain, and severe pain) after 24 h, 48 h, 72 h, and 7 days. Patients were also asked to record the number of prescribed analgesic medication tablets taken at these time points.
There was a statistically significant difference ( = 0.00) among the reciprocating file systems and continuous file systems regarding the incidence of postoperative pain after 24, 48, and 72 h which signifies that pain incidence and duration is less with respect to reciprocation instrumentation as compared to continuous instrumentation.
The use of Reciproc instrumentation system (WOG and RB) showed significantly less intensity and duration of posttreatment pain compared to the single-file rotary system (OC and VB) in patients with symptomatic irreversible pulpitis with apical periodontitis.
本研究旨在比较使用两种往复式和两种连续旋转锉系统进行一次性根管治疗后术后疼痛的发生率。
选取104颗恒牙下颌尖牙和第一前磨牙进行研究，分为两组，每组52颗牙。第1组使用往复式锉系统治疗，再分别使用WaveOne Gold（WOG）和Reciproc Blue（RB）分为两个亚组A和B。第2组使用连续旋转锉系统治疗，分别使用One Curve（OC）和Vortex Blue（VB）分为两个亚组A和B。治疗均在一次性就诊时完成。就诊后，若患者出现疼痛，给予其布洛芬400 mg的处方，要求每6小时服用一次。参与者需根据视觉模拟量表，在术后24小时、48小时、72小时和7天时，对术后疼痛强度按照四级分类（无疼痛、轻度疼痛、中度疼痛和重度疼痛）进行评分。患者还需记录在这些时间点服用的处方止痛药物片数。
在术后24小时、48小时和72小时，往复式锉系统和连续旋转锉系统在术后疼痛发生率方面存在统计学显著差异（P = 0.00），这表明与连续器械操作相比，往复器械操作的疼痛发生率和持续时间更低。
对于有症状的不可逆性牙髓炎伴根尖周炎患者，与单根管旋转系统（OC和VB）相比，使用往复器械系统（WOG和RB）显示治疗后疼痛的强度和持续时间明显更低。
