Influence of Temperature Dependent Properties on Tunneling Cracks in Multi‐Layer Polymer Thin Films

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Tunneling cracks severely compromise the mechanical integrity of multi‐layer polymer thin films on stiff substrates. Although previous models assume a constant elastic modulus, this study characterizes four candidate thermoset polymers. Their elastic modulus (E$$ E $$), coefficient of thermal expansion (CTE), and glass transition temperature ...

Multicenter RCT 6‐Year Survival of Zirconia‐Reinforced Lithium Silicate Endocrowns: 90° Shoulder Versus Butt‐Joint Margins

International Endodontic Journal, EarlyView.
ABSTRACT Objectives Margin design significantly influences endocrown biomechanical performance. Nevertheless, long‐term clinical data comparing margin designs within a singular zirconia‐reinforced lithium silicate (ZLS) system remain scarce. This study reports the 6‐year follow‐up results of a multicenter, prospective, randomized, assessor‐blinded ...

Bond Strength to Gutta‐Percha of a Novel Phase‐Stable Epoxy Resin Sealer Compared With Six Endodontic Sealers

International Endodontic Journal, EarlyView.
ABSTRACT Aim To evaluate the bond strength of the reformulated epoxy resin‐based sealer AH Plus Ribbon to gutta‐percha using a previously described microshear bond strength test, and to compare its performance with that of six commercially available endodontic sealers representing different chemical classes.

Local and Systemic Risk Factors of Dental Biofilm‐Induced Gingivitis and Their Control: A Systematic Review

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Objectives To identify local and systemic risk factors/indicators for dental biofilm‐induced gingivitis (DB‐GI) and to summarize evidence for their control. Methods A systematic review was undertaken following Preferred Reporting Items for Systematic Review and Meta‐Analyses (PRISMA) guidelines and divided into PECOTS and PICOTS questions ...
