Effect of argon plasma and dentin rehydration on bond strength of dental adhesives to etched dentin.

This study investigated the effects of nonthermal atmospheric pressure plasma (NAPP) application and dentin rehydration with water (REHY) on bond strength (BS) of adhesives. Three etch-and-rinse adhesives were tested: Scotchbond Multi-Purpose (SBM / water-based primer + adhesive resin), Gluma Bond Universal (GBU / single-bottle containing acetone as organic solvent) and Prime&Bond Universal (PBU / single-bottle containing propanol as organic solvent). Adhesives were applied: 1- to phosphoric acid-etched dentin (Control), 2- after NAPP application for 45 seconds to etched dentin or 3- after REHY with water (10 seconds) of plasma-treated etched dentin.

Studyholism and Attachment Style: A Study among Italian University Students.

Studyholism (or obsession with studying) is a new potential clinical condition introduced in the literature in 2017. Since then, growing research has supported its conceptualization as a clinical disorder and highlighted some potential intervention targets, namely trait worry, social anxiety, negative interpretation bias, and defense mechanisms. The present study aims to extend the literature concerning psychodynamic-related constructs that might constitute targets for interventions aimed at reducing Studyholism by investigating the role of attachment in 1073 students ( = 23.

Radiotherapy plus pembrolizumab for advanced urothelial carcinoma: results from the ARON-2 real-world study.

The addition of metastasis-directed radiotherapy (MDRT) to immunotherapy in patients with advanced urothelial carcinoma (aUC) has shown promising results. We report the real-world data from the ARON-2 study (NCT05290038) on the impact of conventional (CRT) or stereotactic body radiotherapy (SBRT) on the outcome of aUC patients receiving pembrolizumab after platinum-based-chemotherapy. Medical records of 837 patients were reviewed from 60 institutions in 20 countries.

Effect of phosphoric acid etching and blasting with aluminum oxide on the enamel topography and adhesion of resin composite to intact or abraded enamel.

Objectives: To evaluate the effects of the phosphoric acid (PA) etching, self-etching technique (SE) and blasting with AlO particles (BL) on the bonding of a dental adhesive to intact (INT) or abraded (ABR) enamel.

Methods: Enamel surfaces were treated as follows: 1- ABR-PA: INT was abraded with SiC paper and etched with PA (20 s) before Clearfil Universal Bond Quick adhesive application; 2- ABR-SE: ABR was SiC and adhesive applied in SE mode; 3- INT-PA: INT was etched with PA and adhesive applied; 4- INT-SE: the adhesive (SE mode) was applied to INT; 5- INT-BL: INT was BL and the adhesive was applied (SE mode), and 6- INT-BA: INT was BL, etched with PA and adhesive applied (SE mode). The enamel surface treated was examined with scanning electron microscopy (SEM) (n = 3) and AlO particles were characterized using SEM and EDX.
