Evaluation of Apical Extrusion of Debris with Tactile Controlled Activation Technique Using Controlled Memory Files in Curved Root Canals: An Study.

Background And Objectives: The purpose of the study was to quantify the amount of debris that was extruded apically when single-length and tactile controlled activation (TCA) techniques were used to instrument curved canals.

Materials And Methods: A total of forty mandibular first molars having curved mesial roots of standardized length were subjected to instrumentation, utilizing both single-length and TCA techniques. Pre-weighed Eppendorf tubes were used to collect the extruded debris.

Effect of Finisher Gentlefile brush, XP-endo Finisher and ultrasonic irrigation for the removal of calcium hydroxide paste from root canal.

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.
