The aim of this study was to evaluate the capacity conventional irrigation, passive ultrasonic irrigation (PUI), and Easy Clean for removing calcium hydroxide-based root canal dressing from oval canals. Thirty mandibular uniradicular incisors with canals were used, subjected chemical-mechanical preparation Reciproc R40 instruments. main filled a paste based on Ca(OH)2 P.A., iodoform propylene glycol in ratio 3:1:1. teeth stored 100% humidity at temperature 37°C 14 days. Afterwards, divided...
Abstract Aim To evaluate the influence of larger apical canal enlargement in curved canals using reciprocating systems subjected to various heat treatments. Methodology Ninety mandibular premolars with root curvatures ranging from 20° 30° were selected and scanned by microcomputed tomography (micro‐ CT ) before after preparation ( n = 30): Reciproc Blue RB size 25, .08 taper 40, .06 taper; VDW , Munich, Germany), WaveOne Gold WOG .07 35, Dentsply Sirona, Ballaigues, Switzerland) ProDesign R...
Abstract The aim of this study was to compare the root canal instrumentation techniques that involve foraminal enlargement versus those not involving it, in regard apical extrusion filling material, using micro‐computed tomography (micro‐CT). Twenty‐two premolars with single canals were instrumented ProTaper Universal System and then randomly divided into two groups ( n = 11): Group NFE, without enlargement, FE, enlargement. Instrumentation performed up 1 mm short foramen, patency maintained...
