Wave One (WO) and One Shape (OS) are among the common endodontic file systems having rotary and reciprocating movement of instrument, respectively. The study evaluated the postoperative pain after single-visit root canal treatment using single file rotary and reciprocating system.
The present study was conducted in the department of conservative dentistry and endodontics on 68 teeth of patients aged between 20 and 45 years. Sixty-eight teeth were divided into two study groups. In Group A, instrumentation with OS file systems ( = 34) was done with subgroup A1 having patients without periapical lesion ( = 17) and subgroup A2 having patients with periapical lesion ( = 17). In Group B, instrumentation with WO file systems ( = 34) was done with subgroup B1 having patients without periapical lesion ( = 17) and subgroup B2 having patients with periapical lesion ( = 17). The root canal shaping procedures were performed according to the manufacturer's instructions for each instrument system. Presence of postobturation pain was accessed by visual analog scale (VAS) scale (0-10), where 0 showed no pain, 1-3 mild pain, 4-6 moderate pain, 7-9 severe pain, and 10 worst possible pain.
The intensity of pain was measured with VAS score in patients without periapical lesions and with periapical lesions using WO and OS file system on the 1, 2, 3, and 7 day. VAS score was found to be nonsignificant on the 1, 2, 3, and 7 day in both groups ( > 0.05). Intergroup comparison of VAS score was found to be nonsignificant ( > 0.05).
Both systems were found to have similar effect with respect to postoperative pain. However, WO single file system presented less pain as compared to OS system in cases with periapical lesion. Large sample studies are required to substantiate the result obtained in this study.
Wave One（WO）和One Shape（OS）是常见的根管锉系统，其器械分别具有旋转和往复运动。本研究评估了使用单根管旋转和往复系统进行单次就诊根管治疗后的术后疼痛情况。
本研究在保守牙科与牙髓病科对68颗年龄在20至45岁患者的牙齿进行。68颗牙齿分为两个研究组。A组使用OS锉系统进行根管预备（n = 34），其中A1亚组为无根尖周病变的患者（n = 17），A2亚组为有根尖周病变的患者（n = 17）。B组使用WO锉系统进行根管预备（n = 34），其中B1亚组为无根尖周病变的患者（n = 17），B2亚组为有根尖周病变的患者（n = 17）。根管预备程序根据每个器械系统的制造商说明进行。通过视觉模拟量表（VAS）（0 - 10）评估根管充填后疼痛情况，其中0表示无疼痛，1 - 3为轻度疼痛，4 - 6为中度疼痛，7 - 9为重度疼痛，10为最严重疼痛。
在第1、2、3和7天，使用WO和OS锉系统对无根尖周病变和有根尖周病变的患者进行VAS评分以测量疼痛强度。两组在第1、2、3和7天的VAS评分均无统计学意义（P > 0.05）。VAS评分的组间比较也无统计学意义（P > 0.05）。
两种系统在术后疼痛方面效果相似。然而，在有根尖周病变的病例中，WO单根管系统比OS系统疼痛程度轻。需要大样本研究来证实本研究所得结果。
