Effect of hydroxyapatite and 45S5 bioactive glass addition on a dental adhesive resin cement

Abstract

Owing to their adequate adhesive, esthetic, and mechanical properties resin-based cement has been widely used in dental practice to bond metallic, ceramic, or polymeric indirect restorations (crowns, veneers, inlays, onlays, or fixed partial dentures) in mineralized dental tissues. 1-3 Compared to conventional types of cement, like zinc phosphate and glass ionomer, resin-based cement has improved adhesive and mechanical properties and it is less soluble. 2-4 However, because of their potential cytotoxic effect on pulp-dentine complex 5-7 and the possible occurrence of postoperative hypersensitivity owing to the absence of hermetical sealing on the tooth/cement interface provoked by a

Effect of bioactive glass particles on mechanical and adhesion properties of resin cements

“…In a study conducted by Valanezhad et al, the addition of 3% and 5% sol-gel derivative BAG nanoparticles increased the flexural strength of RMGICs by 5%-70% [16]. However, studies on the addition of BAG to resin cements are limited [6]. As in the study conducted by Assad et al, the addition of BAG reduced the flexural strength in the current study [6].…”

“…The mechanical and adhesive properties of resin cements have continued to improve through various modifications and content changes in materials [6,27]. In this study, 5% and 10% BAG were added to three resin cements in order to improve the mechanical and adhesive properties of resin cements.…”

“…While the content of the majority of resin cements is similar to that of dental composites, commercially available products have various physical and mechanical differences owing to their type, size, and amount of diluent monomer or filler particles [4,5].According to the matrix formation mechanism, adhesive cements are classified as follows: (1) light-activated curing, (2) self-or auto-curing, and (3) dual curing [1]. Compared with conventional cements, adhesive cements have improved adhesion and mechanical properties [6,7]. However, polymerization shrinkage of these ce-ments causes marginal integrity deterioration and micro-leakage of the restorations, which could significantly shorten the lifetime of the restorations [6,8,9].…”

However, polymerization shrinkage of these ce-ments causes marginal integrity deterioration and micro-leakage of the restorations, which could significantly shorten the lifetime of the restorations [6,8,9]. One method of ensuring the longevity of dental restorations is to provide a tight connection between the tooth and restoration and create an environment that prevents bacterial adhesion [10].…”
