This clinical trial sought to evaluate the effectiveness of alternative treatment for replacing amalgam and resin-based composite restorations with marginal defects. The study recruited 66 patients with 271 restorations. Each restoration was assigned randomly to one of five groups: Sealant, Refurbishing, Repair, Replacement, and Untreated. Two clinicians evaluated the restorations according to USPHS/Ryge criteria at baseline (Kappa 0.74) and one year after the treatment (Kappa 0.81). The scoring of the margins improved (from bravo to alfa) after the experimental treatments. None of the treatments showed significant degradation of the margins during the 12-month observation period.

Department of Restorative Dentistry, Faculty of Dentistry, Bolu Abant Izzet Baysal University, Bolu, Turkey.
Objective: To compare the translucency and contrast ratio of 13 different resin based restorative materials and to evaluate the effect of 2 different bleaching methods on the translucency and contrast ratio of these materials.
Methods: In this study, a total of 260 samples were prepared, 20 from each of 13 different dimethacrylate-based restorative materials. Then, each material group was divided into 4 subgroups.
Comparing Polymerization Shrinkage Measurement Methods for Universal Shade Flowable Resin-Based Composites.
Biomimetics (Basel)

Department of Operative Dentistry, Aichi Gakuin School of Dentistry, Nagoya 464-8651, Japan.
Universal shade flowable composites have been introduced to mimic tooth structure with reduced color mismatch and reduced chair time and cost. However, the polymerization shrinkage of resin material may lead to sensitivity and restoration failure. The purpose of this study was to compare the polymerization shrinkage of recently introduced universal shade flowable resin-based composites using both wet and dry density methods.

Objectives: To identify and map the literature on the current state of pH-triggered strategies for resin-based materials used in direct restorative dentistry, focusing on innovative compounds, their incorporation and evaluation methods, and the main outcomes.
Data And Sources: Through a search across PubMed, Scopus, Embase, Web of Science, LILACS, Cochrane Library databases, and Google Scholar, this review identified studies pertinent to pH-responsive dental materials, excluding resin-modified glass ionomer cements.
Study Selection: From the 981 records identified, 19 in vitro studies were included, concentrating on resin-based composite resins (50 %), dentin adhesives (25 %), and sealants (25 %).
Investigating the impact of whitening toothpastes on bioactive resin-based restorative materials: a comparative analysis.
BMC Oral Health
December 2024
Department of Restorative Dentistry, Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia.
Objective: To assess the color stability and surface roughness of bioactive resin-based composite following exposure to coffee staining and brushing with whitening toothpastes.
Methods: Disk-shaped specimens of Filtek Z250 (FZ), Beautifil Flow Plus (BFP), Activa Presto (AP), and Fuji II LC (FII) were stained with coffee and then brushed with one of three toothpastes, conventional (C-TP), non-peroxide whitening (W-TP) or hydrogen peroxide-containing whitening toothpaste (HPW-TP) for 10 000 cycles. Changes in color (ΔE) and surface roughness were measured.
Effect of Food-Simulating Liquids on Hydrolytic Behavior of Resin Matrix Ceramics.
Int J Prosthodont
December 2024
Purpose: This study aimed to evaluate the hydrolytic behavior of different computer-aided design/computer-aided manufacturing (CAD/CAM) resin matrix ceramics (RMCs) in different food-simulating liquids (FSLs).
Materials And Methods: Five different CAD/CAM blocks, one from polymer-infiltrated ceramic networks (PICNs; Vita Enamic (EN)) and four from resin-based composites (RBCs; Lava Ultimate (UL), Cerasmart (CER), Brilliant Crios (BR), and Block HC (HC)) were selected. Forty specimens were prepared for each material, and they randomly distributed to each FSLs.
