Comparison of Debris Extrusion and Instrumentation Time Among ProTaper Next, Neoniti, and M3‐Pro Gold Rotary Systems: An In Vitro Study

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
Background and Objectives: Reducing apical extrusion of debris and reducing instrumentation time are desirable outcomes of rotary instruments. However, information regarding the performance of newer file designs in these areas is limited. This study aimed to compare the apical extrusion of debris and instrumentation time during root canal preparation ...

Shaping ability of three instrumentation system in moderately curved canals: A micro‐CT study

Microscopy Research and Technique, Volume 87, Issue 10, Page 2399-2407, October 2024.
TRN, which provides a controlled increase in canal volume, can be used in thin dentin such as the danger zone, however, its use should be supported by copious irrigation and brushing considering the rate of untouched dentin walls. Abstract This study aims to compare the shaping ability of three systems using micro‐computed tomography (micro‐CT ...

Assessment of Debris Extrusion in Curved Canals: An In Vitro Analysis of Various Single‐File Endodontic Instrumentation Systems

International Journal of Dentistry, Volume 2024, Issue 1, 2024.
Objectives. Rotary single‐file endodontic systems are commonly used for root canal treatment. However, very few studies have evaluated the apical extrusion of debris generated by these systems during canal preparation at normal body temperature in laboratory conditions. The aim of this study was to evaluate the amount of apically extruded debris caused

Characteristics and Effectiveness of XP‐Endo Files and Systems: A Narrative Review

International Journal of Dentistry, Volume 2024, Issue 1, 2024.
Background: XP‐endo files are composed of Max‐Wire alloy, which was developed by FKG Dentaire (La Chaux‐de‐Fonds, Switzerland). This alloy, known as Martensite‐Austenite Electropolish Flex, is the first NiTi alloy used in endodontics to combine the shape memory effect with superelasticity for use in clinical practice.
