COMPARISION OF THE INCIDENCE OF POSTOPERATIVE PAIN AFTER USING TWO CONTINUOUS ROTARY FILE SYSTEM WITH CONVENTIONAL NEEDLE AND ULTRASONIC IRRIGATION IN SINGLE VISIT ENDODONTICS: AN INVIVO STUDY

Abstract

Aim: The aim of this study was to compare the incidence of postoperative pain after using protaper gold (Dentsply Maillefer) and Neoendo (Orikam) rotary file system with conventional needle and ultrasonic irrigation system in single visit endodontics.

Materials and Methods: Sixty patients requiring endodontic therapy were included in this study and divided into four groups, each group consisting of 15 patients. Group I (n = 15), was instrumented using ProTaper Gold followed by needle (Neoendo side vent) irrigation using 2 ml 3% sodium hypochlorite. In Group II, teeth were instrumented using ProTaper Gold followed by 3% sodium hypochlorite irrigant and activated using Endoactivator (Orikam Ultra X)  for 30 seconds. In Group III (n = 15), teeth were instrumented using Neoendo (Orikam) rotary file system followed by conventional needle irrigation using 3% sodium hypochlorite as mentioned in Group I. In Group IV  (n = 15), teeth were instrumented using Neoendo rotary file system followed by 3% sodium hypochlorite irrigant which were activated using Endoactivator for 30 seconds as mentioned in Group II. Each root canal will be obturated using the single cone technique using Zinc oxide sealer. Postoperative pain response of patients was evaluated using the visual analogue scale (VAS) score. Results: For VAS pain scores, a statistically significant difference was found between the PTG and Neo Endo files (p= 0.000). Group II showed the least incidence of pain for a follow up period of one week followed by Group I and Group IV. Group III showed the highest incidence of pain among the four group. Conclusion: Within the limitations of this study, we may conclude that the PTG system along with the Passive Ultrasonic Irrigation System  is a technique that is able to minimize the risk of postoperative pain after single visit root canal therapy compared to the other technique used in this study. However, all the techniques used in this study significantly reduced the post-operative pain within a time interval of one week.
