Shaping Performance of XP4 versus ProTaper Next in C‐Shaped Canals: A Micro‐CT Study of 3D‐Printed Mandibular Second Molar Replicas

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Introduction This micro‐computed tomography (micro‐CT) study aimed to evaluate the shaping ability of two nickel–titanium (NiTi) rotary systems—XP4 and ProTaper Next (PTN)—in 3D‐printed replicas of C‐shaped canals. Methods Two extracted mandibular second molars with C‐shaped root canals—one continuous (Melton's Category I) and one ...

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

Australian Endodontic Journal, Volume 52, Issue 2, Page 585-605, August 2026.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

Comparison of Apical Transportation and Canal Straightening Between Protaper Next, Hyflex, Reciproc and Reciproc Blue Instruments

Selcuk Dental Journal, 2022
Background: The effective bonding of fiber posts which are recommended in the restoration of endodontically treated teeth with excessive coronal damage is of critical importance for the long-term success. The aim of this study was to investigate the effect of various irrigation activation protocols on the push-out bond strength of fiber posts in ...

A Novel Laboratorial Approach to Evaluate Bacterial Microleakage of Endodontic Sealers

Current Protocols, Volume 6, Issue 7, July 2026.
Abstract To avoid failure of endodontic treatment, it is important to properly seal the root canals after chemomechanical preparation in order to avoid microleakage. Typically, sealing involves the use of gutta‐percha and sealing cement, the latter of which adheres to the dentin and fills the spaces between the gutta‐percha and the dentin walls ...

Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

Australian Endodontic Journal, Volume 52, Issue 1, Page 156-167, April 2026.
ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...
