An Observational Study To Evaluate The Impact Of Different Single-File Systems Used In Single-Visit Endodontics On The Incidence And Severity Of Postoperative Pain

Abstract

Context: Pain, although of short duration, is a thwarting experience and a matter of concern after single-visit endodontics.

Aim: This study aims to evaluate the impact of different single-file systems used in single- visit endodontics on postoperative pain.

Design: This is an observational study involving one hundred fifty patients out of which thirty failed to participate. Therefore, one hundred twenty patients were selected as subjects for the study.

Materials and Methods: Patients aged between 18-55 years with symptomatic irreversible pulpitis with/without apical periodontitis and fully matured mandibular premolar teeth were selected and categorized into three groups based on instrumentation system used: Group I with WaveOne Gold, Group II with One Curve and Group III with TruNatomy. The root canal preparation procedures were performed according to the manufacturer's instructions. Presence of pain was accessed by modified Heft-Parker visual analogue scale (HP-VAS) scale.

Statistical analysis: Data were collected after obtaining the HP-VAS forms and one-way ANOVA and one-way repeated measure ANOVA were used for analysis The level of statistical significance was set at P<0.05.

Results: The intensity of pain was measured on 24, 48 and 72 hours. All the three groups showed less postoperative pain at 72 hours where the difference is statistically significant. After 24 hours, pain was seen least with TruNatomy, followed by One Curve and WaveOne Gold, but here the results were statistically insignificant.

Conclusion: Postoperative pain is mainly related to the instrumentation technique although there may be other contributory factors too.
