Abstract
Aim: The objective of this randomized clinical trial was to clinically evaluate the incidence of postoperative pain after root canal treatment in symptomatic irreversible pulpitis of multi-rooted teeth using two different instrument design rotary file systems, namely Protaper Next (PTN) and V taper 2H (VT2H).
Methods: In this prospective randomized clinical trial 60 patients with symptomatic irreversible pulpitis of multirooted teeth, indicated for root canal therapy, were randomly assigned to two groups according to instrument system used viz. PTN, VT2H. Root canal treatments were performed in single visit. After treatment, the participants were asked to rate the intensity of postoperative pain on modified verbal descriptor scale after 8hrs, 24hrs, 48hrs, and 72hrs over the telephone by a second investigator. Patients were advised to call the second investigator by telephone if they felt very uncomfortable at any point of the follow-up time. At that time, they were asked to take Ibuprofen 200mg as the rescue drug.
Results: No statistically significant difference was found among the two groups in relation to postoperative pain and intake of analgesic medication at four time points assessed (p> 0.05, Kruskal-Wallis test).
Conclusion: The Protaper Next system and V taper 2H rotary system were found to be equal in the incidence of postoperative pain and pain intensity was found to decrease with time, post operatively, in both the rotary systems.
Relevance for patients: The instrument design has little effect on postoperative pain in symptomatic irreversible pulpitis patients after single visit root canal therapy.
