Background: 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. Materials and Methods: 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 (n = 34) was done with subgroup A1 having patients without periapical lesion (n = 17) and subgroup A2 having patients with periapical lesion (n = 17). In Group B, instrumentation with WO file systems (n = 34) was done with subgroup B1 having patients without periapical lesion (n = 17) and subgroup B2 having patients with periapical lesion (n = 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. Results: 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 1st, 2nd, 3rd, and 7th day. VAS score was found to be nonsignificant on the 1st, 2nd, 3rd, and 7th day in both groups (P > 0.05). Intergroup comparison of VAS score was found to be nonsignificant (P > 0.05). Conclusion: 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. |
