Abstract

Abstract: The aim of this study was to compare the efficacy of UAI with ESI, sonic activation with Eddy ® and syringe irrigation in removing debris, and dentin removal during canal irrigation. Twenty‐four mandibular molars containing isthmus type V and with a mean curvature of 32.5° were instrumented and divided into three groups for final irrigation: UAI with ESI, sonic activation with Eddy and syringe irrigation. The samples were scanned in a SkyScan 1172 micro‐CT device for pre‐, post‐instrumentation and post‐irrigation images and analysis of dentin removal. Statistical analysis was performed using Wilcoxon, Kruskal–Wallis and Dunn tests. UAI and sonic activation significantly improved debris removal ( P < 0.05). No significant difference was observed regarding dentin removal between the groups ( P > 0.05), although higher values were found for UAI. Sonic activation with Eddy ® showed to be an effective and safe device since it was able to remove debris without causing damage to the canal walls.
