Objective: This study evaluated the efficacy of the ProTaper Universal Retreatment system (PTUR) and XP-endo Finisher R instrument (XPFR) in removing 64-month-old root filling material from minimally-instrumented mandibular molar canals.
Methods: Forty-eight root canals with Vertucci type II or IV configurations from 30 mandibular molars were instrumented to size 20/0.04 taper using Vortex Blue NiTi rotary instruments and irrigated with the GentleWave system.

Objective: To evaluate the efficacy of supplementary methods, including Passive Ultrasonic Irrigation (PUI), ultrasonic inserts, XP-Endo Finisher, XP-Endo Finisher R, Easy Clean, sonic activation, and the Er:YAG laser (SWEEPS), in removing residual filling material (RFM) during endodontic retreatment.
Method: Five electronic databases and gray literature were searched on May 5, 2024. Two independent reviewers selected laboratory studies that assessed the efficacy of supplementary methods for RFM removal using micro-CT imaging.

Context: The smear layer may harbor many bacteria; hence, alternative methods are used to disrupt and remove biofilm.
Aim: The aim of the study was to compare the effectiveness of EndoActivator, PATS Vario System, and XP-endo Finisher files on smear layer removal using a scanning electron microscope.
Subjects And Methods: Sixty single-rooted extracted premolars with Vertucci Type 1 configuration were decoronated and divided into four groups.

Objectives: This study aimed to assess the efficacy of different activation techniques in removing calcium hydroxide (Ultracal XS), Ledermix, and Bio-C Temp from simulated internal root resorption (IRR) cavities.
Materials And Methods: 108 single-rooted maxillary incisors were prepared using Reciproc R50 files. Simulated IRR cavities, 2 mm in diameter and located 8 mm from the apex, were created.
