Postoperative quality of life following single-visit root canal treatment performed by rotary or reciprocating instrumentation: a randomized clinical trial

Aim To compare the impact of rotary and reciprocating instrumentation on postoperative quality of life (POQoL) after single‐visit primary root canal treatment. Methodology A randomized controlled clinical trial was designed and carried out in a University endodontic practice in northern Italy. Healthy subjects with asymptomatic irreversible pulpitis, symptomatic irreversible pulpitis or pulp necrosis with or without apical periodontitis (symptomatic or asymptomatic) scheduled for primary root canal treatment were enrolled. Single‐visit root canal treatment was performed with ProTaper™ S1‐S2‐F1‐F2 (rotary group, n = 23) and WaveOne™ Primary (reciprocating group, n = 24). Irrigation was performed with 5% NaOCl and 10% EDTA. Root canal filling was performed with the continuous‐wave technique and ZOE sealer. POQoL indicators were evaluated for 7 days post‐treatment. The variation of each indicator over time was compared using anova for repeated measures (P
