Eliminating residual calcium hydroxide [Ca(OH)] intracanal medicament from the walls of a root canal presents a persistent obstacle that can impede the establishment of a proper fluid-tight seal during obturation. The effective removal of these medicaments from the canal walls has consistently posed a significant challenge. Consequently, several systems have been developed and assessed in order to address this issue. Therefore, it is of interest to compare the efficacy of Finisher Gentlefile Brush, XP-endo Finisher and Passive Ultrasonic Irrigation (PUI) on the removal of an oil-based Ca(OH) paste. 60 human mandibular extracted premolars were selected and underwent preparation with Pro Taper Gold rotary file system till size F5. The canals were dried and filled with Metapex and stored for a week. Further, the specimens were divided into 3 groups depending upon the Metapex removal protocols, namely, Finisher Gentlefile Brush, XP-endo Finisher, and PUI. Afterward, the specimens were sectioned buccolingually. Evaluation of remnants was done with a scoring system under a dental microscope at 25x magnification. The data was analyzed using the Chi-square test (p<.05). With the exception of PUI, all the methods demonstrated significantly better performance, with Finisher Gentlefile Brush being the most effective across all canal thirds (p<.05). While none of the methods achieved complete cleanliness, Finisher Gentlefile Brush exhibited exceptional results compared to the other two systems employed.

Introduction: In this study, the cleaning ability of a stainless-steel rotary instrument called Gentlefile, was compared with three nickel-titanium rotary instruments.
Materials And Methods: In this study, forty mandibular single-rooted premolars were randomly assorted into four groups: Gentlefile, ProTper Universal, RaCe files, and XP-Endo Finisher/ProTaper Universal system (=10). Final instrumentation was done using the aforementioned files with 5.
Objective: To carry out a morphometric analysis of small oval root canals prepared with different instruments (part 1) and filled with different sealers (part 2).
Method And Materials: Ninety extracted mandibular incisors with small oval root canals were instrumented with Self-Adjusting File (n = 45), XP-endo Finisher (n = 15), GentleFile (n = 15), or Reciproc (n = 15). All groups of part 1 were filled with AH Plus (n = 15 each).
Introduction: The full decontamination and disinfection of the root canal system is essential for the success of regenerative endodontic procedures. The current literature does not have information regarding mechanical cleaning of immature teeth with contemporary endodontic instuments.
Aim: To compare the thickness and volume of the dentin removed from the roots of immature teeth after endodontic preparation using XP-endo Finisher, GentleFile Brush and a standard H-file scraping technique through micro-computed tomography.

Aim: To examine the efficacy of a novel supplementary irrigant agitating brush (Finisher GF Brush, MedicNRG, Kibbutz Afikim, Israel) on the debridement of root canals prepared with a novel stainless steel rotary instrumentation system (Gentlefile; MedicNRG), or nickel titanium rotary instruments in oval root canals.
Methodology: Mandibular premolars (n = 72) were selected and divided randomly into three experimental groups (n = 24) after microCT scanning: group 1, canal preparation to rotary NiTi size 20, .04 taper (R20); group 2, rotary NiTi to size 25, .
