Objectives
The aim of this prospective clinical trial was to investigate the incidence of postoperative pain after initial root canal treatment using Twisted File Adaptive (TFA) and Reciproc systems.
Materials and methods
A total of sixty-four previously initiated or necrotic posterior teeth were randomly assigned to two groups based on the rotary system used; TFA (SybronEndo, Orange, Ca) (n = 35) and Reciproc (VDW, Munich, Germany) (n = 29). All teeth were treated in a single visit. Patients were contacted to assess the level of postoperative pain on a visual analog scale after treatment by 6 h, 24 h, 48 h, 72 h, and 1 week. Patients were also asked to report if any medication was taken during the follow-up period. The postoperative pain scores were analyzed by Mann-Whitney test with respect to follow-up interval at a significance level of 0.05.
Results
Patients treated with TFA reported significantly lower postoperative pain levels at 24 h, 48 h, and 72 h compared with those in Reciproc group (p < 0.01). There were no significant differences between the two groups at 6 h and 1-week follow-up intervals (p > 0.05). About 11% (TFA) and 24% (Reciproc) of the treated patients took analgesics, but none of them took antibiotics during the follow-up period.
Conclusions
The tested rotary systems induced postoperative pain after root canal treatment. The TFA system was found to induce less pain scores compared with the Reciproc system after the treatment by 24 h, 48 h, and 72 h.
Clinical relevance
The level of postoperative pain was low after the root canal treatment with the Twisted File Adaptive system compared with the Reciproc system.
