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 ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Fatigue behaviour of root filled teeth: The role of endodontic sealers and restorative techniques

European Journal of Oral Sciences, Volume 134, Issue 3, June 2026.
Abstract This in vitro study aimed to evaluate the fatigue behaviour of root canal treated teeth, filled with either AH Plus Jet (AHP) or AH Plus Bioceramic Sealer (AHPB) and rehabilitated with either mesio‐occlusal‐distal (MOD) restorations (direct resin composite) or endocrowns (indirect resin composite).

Influence of Engine‐Driven NiTi Files on the Effectiveness and Technical Quality of Endodontic Treatment Performed by Undergraduate Students: A Systematic Review and Meta‐Analysis

International Endodontic Journal, Volume 59, Issue 6, Page 968-985, June 2026.
ABSTRACT Background In recent years, many universities have incorporated engine‐driven nickel‐titanium (NiTi) instruments into their undergraduate endodontic programs, aiming to enhance the efficiency and precision of root canal treatments. While these techniques might offer advantages, concerns remain regarding their implementation, particularly in ...
