Effectiveness of self‐etching ceramic primer on the bond strength of dental glass ceramics: A systematic review and meta‐analysis of in vitro studies on feldspathic and leucite‐reinforced ceramics

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review and meta‐analysis evaluated the bond strength effectiveness of a self‐etching ceramic primer, specifically Monobond Etch & Prime (MEP), compared to hydrofluoric acid with silane (HF+S) in feldspathic and leucite‐reinforced dental glass‐ceramics (DGCs). Materials and Methods This study followed PRISMA‐p guidelines

Hydraulic fast‐setting calcium silicate cement for crown cementation

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated film thickness, diametral tensile strength (DTS), and crown retentive strength of hydraulic fast‐set calcium silicate cement (fast‐set CSC) compared to conventional luting cements. Materials and Methods Fast‐set CSC was compared to zinc phosphate cement and glass ionomer cement.

Role of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on immediate implant placement in type 2 diabetic rats

Photochemistry and Photobiology, EarlyView.
This study evaluated the combined effects of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on bone repair around immediately placed implants in type 2 diabetic rats. Resveratrol improved glycemic control and body weight, while aPDT increased implant stability and bone mineralization.
