Periodontitis and its association with left ventricular geometry and function: A cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigated the cross‐sectional association between periodontal status and left ventricular (LV) geometry and function, an early and prognostically relevant marker of cardiovascular disease. Methods Data were drawn from two population‐based cohorts in the Study of Health in Pomerania (SHIP): SHIP‐START‐2 (N = 2333) and ...

Static and free vibration of axially loaded functionally graded beams based on the first-order shear deformation theory [PDF]

open access: yes, 2013
The first-order shear deformation beam theory for static and free vibration of axially loaded rectangular functionally graded beams is developed. In this theory, the improved transverse shear stiffness is derived from the in-plane stress and equilibrium ...

Novel nitro‐quinoline photoinitiators for composites: exploring the effects of hydroxyl and methacrylate substituents on the photopolymerization of dimethacrylate matrices

open access: yesPolymer International, EarlyView.
New quinoline derivatives proved to be efficient photoinitiators for dental resin monomers under two different light‐curing units, yielding favorable conversion, color and fluorescence results in the presence of different co‐initiators, including an eco‐friendly alternative.

Tooth Sensitivity, Bleaching Efficacy, and Quality of Life in Young People and Adults: A Stratified, Randomized Bi‐Center Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study compared tooth sensitivity, bleaching efficacy, and the impact on oral health‐related quality of life between at‐home and in‐office tooth bleaching in adults and young individuals. Materials and Methods Eighty participants, 40 young people (14–20 years) and 40 adults (40–60 years), were randomly assigned to receive either

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

open access: yesJournal 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 ...

Air‐Abrasion With Aluminum Oxide Particles in Non‐Carious Cervical Lesions: Impact on Sclerotic Superficial Layer, Surface Topography, and Restorative Adhesive Performance

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of airborne‐particle abrasion (APA) with aluminum oxide on superficial dentin sclerosis, surface topography, and bonding performance of a universal adhesive in natural non‐carious cervical lesions (NCCLs), using dentin classification by the North Carolina Index (NCI) and Optical Coherence Tomography Index (OCT).
