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 ...

Measuring MAN (incorporating JRAI): Computational anthropological analysis and quantitative speculation

Journal of the Royal Anthropological Institute, Volume 32, Issue 1, Page 32-54, March 2026.
Abstract In this paper, we present a foray into the computational study of anthropological texts. Drawing on a corpus of approximately 2,500 articles published in the Journal of the Royal Anthropological Institute (formerly Man) from 1950 to 2018, we discuss selected findings from the deployment of two methods for computational text analysis, namely ...
