Clinical outcome of guided endodontics versus freehand drilling: A controlled clinical trial, single arm with external control group

International Endodontic Journal, Volume 58, Issue 2, Page 209-224, February 2025.
Abstract Aim High‐quality, prospective clinical studies are needed to increase evidence for guided endodontics. This study aims to assess the clinical outcome of guided endodontics for treatment of teeth presenting with pulp canal obliteration (PCO) in comparison with freehand treatment. Methodology This trial was registered in the ISRCTN.com registry (

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 ...

Comparative Evaluation of Canal Transport and Centralization Between ProTaper Next and XP‐endo Shaper Systems Using CBCT Analysis: An In Vitro Study

International Journal of Dentistry, Volume 2025, Issue 1, 2025.
Aim: This study compared the apical transportation and centering ratio of ProTaper Next (PTN) and XP‐endo Shaper (XPS) nickel titanium (NiTi) rotary files in curved root canals using cone beam computed tomography (CBCT). Methodology: The current in vitro study involved the mesiobuccal canals of mesial roots in 44 extracted mandibular first molars that ...

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 ...

Fifteen years of engine‐driven nickel–titanium reciprocating instruments, what do we know so far? An umbrella review

Australian Endodontic Journal, Volume 50, Issue 2, Page 409-463, August 2024.
Abstract Numerous systematic reviews (SRs) have produced conflicting findings on engine‐driven nickel–titanium reciprocating instruments (reciprocating instruments) since Yared's seminal study 15 years ago. This umbrella review analysed SRs examining the clinical and laboratory evidence regarding reciprocating instruments for root canal treatment.

Effect of different instrumentation techniques on students’ performance and outcomes of nonsurgical root canal treatment

Journal of Dental Education, Volume 88, Issue 7, Page 940-948, July 2024.
Abstract Objectives This study compared, retrospectively, the incidence of clinical errors and effects on treatment outcomes, when students were exposed to two different instrumentation techniques: a hybrid rotary technique (HYB), consisting of both hand instrumentation with hand stainless steel and Ni‐Ti files plus the use of a rotary system (Vortex ...

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

Comparison of the effect of different glide path files on amount of apically extruded debris in curved root canals.

, 2023
It is essential to create a glide path before root canal preparation with nickel–titanium rotary files to avoid file breakage and preserve the original canal structure.
