The present systematic review evaluates the shear bond strength of artificial teeth bonded to CAD/CAM PMMA and heat-cure acrylic resins used in complete denture manufacturing. The study aims to determine the superior bonding material, contributing to enhanced denture durability and patient satisfaction. A comprehensive search of databases including PubMed, MEDLINE, DOAJ, Cochrane Library and Scopus was conducted, adhering to PRISMA 2020 guidelines. Studies were assessed for inclusion based on specific criteria, and the data were analyzed using Review Manager (RevMan) 5.3. The findings suggest that while both materials provide adequate bond strength, differences exist that may influence material choice in clinical practice.

Objective: The aim of this study was to compare the effectiveness of various cleaning protocols on the bond strength of dual-cure resin cement following temporary cementation.
Materials And Methods: Fifty-two human third molars were sectioned to expose superficial dentin and divided into four groups: (1) fresh, noncontaminated dentin (control); (2) pumice cleaning; (3) pumice + sodium bicarbonate air polishing; and (4) pumice + 10-methacryloyloxydecyl dihydrogen phosphate (MDP) based cleaner. Groups 2, 3, and 4 were treated with noneugenol zinc oxide temporary cement, followed by their respective cleaning protocols.

Objective: Despite the emergence of numerous three-dimensional (3D) printed provisional resin, there are no conclusive guidelines for repairing them. This study aims to investigate the effects of different repair materials and surface treatments on the shear bond strength of 3D-printed provisional resin.
Materials And Methods: A total of 180 3D-printed resin specimens underwent six surface treatments: no surface treatment (control), silicon carbide paper (SP), sandblasting with aluminum oxide (SB), SP followed by SB (SP + SB), SP with bonding agent (SP + BD), and SB with bonding agent (SB + BD).

Intermolecular interaction is a key factor in the fortification of surimi gels by plant protein addition. Here, the effects of different intermolecular interactions, such as ionic, covalent and non-covalent interactions, on gel structure, gelation strength and water-holding properties were investigated, using sturgeon surimi fortified by three walnut isolates, including walnut meal (WM), protein isolate (WPI) and peptide (WP), as representatives. Quantitative creep-recovery analysis and soluble protein assay demonstrated that secondary bonds, mainly hydrophobic interaction and hydrogen bond, possibly played a dominant role in walnut protein-fortified surimi gels.

Background: Increased bond strength between aged CAD/CAM (Computer-Aided Design and Computer-Aided Manufacturing) provisional restorative materials is essential for reparability. This study investigated the impact of three different solvents and airborne-particle abrasion on the shear bond strength (SBS) of aged CAD/CAM provisional restorative materials, which are milled PMMA and 3D-printed resin with flowable resin composite.
Methods: 3D-printed resin and milled PMMA (N = 160 per type) were fabricated into cylindrical shapes (5 mm in diameter, 5 mm in height), aged by 5,000 thermocycling cycles, and randomize divided at random into five groups (N = 32) based on surface modification protocols: control; non-surface modification, MEK; application with methyl ethyl ketone, THF; application with tetrahydrofuran, Alc; application with isopropyl alcohol, and APA; airborne-particle abrasion with 50-µm alumina oxide particle.
