Influence of rubbing during etching on surface roughness and interfacial characteristics of intact enamel

European Journal of Oral Sciences, EarlyView.
Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...

Esthetic and adhesive properties of a novel colored fiber post: A restorative approach to an endodontic challenge

European Journal of Oral Sciences, EarlyView.
Abstract Colored fiber posts facilitate clinical retrieval but could impact esthetics and bonding. This study evaluated the color stability and dentin bond strength of a novel colored fiber post designed to facilitate post‐removal. Sixty premolars had root canal therapy and post space preparation.

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

6‐Month Clinical Evaluation of Reduced Dentin Etching Time Using Universal Adhesives in Noncarious Cervical Lesions: A Double‐Blind Randomized Clinical Trial

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of reduced dentin etching time on the clinical performance of two universal adhesive systems in noncarious cervical lesions (NCCLs). Methods A total of 144 NCCLs restorations were randomly placed in 36 participants according to four experimental groups: SUP5 (Scotchbond Universal Plus adhesive [pH ≈2.5–2.7 ...

Effects of Surface Abrasion With Airborne‐Particles and Surface Etching With Hydrofluoric Acid on Color Difference and Translucency of Nano‐Hybrid Ceramic

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effects of alumina airborne‐particle abrasion, glass‐bead airborne‐particle abrasion, and hydrofluoric acid etching of intaglio surfaces on the color difference and translucency of a nano‐hybrid ceramic after cementation to resin abutment specimens, and to analyze the relationships between surface roughness and these
