Background: There is a technique in the industry called resin procedures like resin coating. For example, epoxy resin is injected to repair cracks in concrete of 0.2 mm or larger. In addition, a casting product can be strengthened when resin is injected to fill in a blowhole. A vacuum can be utilized to allow the resin to penetrate into every corner. In this study, we investigate whether bondin...

This study was evaluated the tensile bond strength (TBS) of resin cements to bovine dentin resin-coated with all-in-one adhesive systems. Each of the dual-polymerizing resin cements; Link Max, Clearfil Esthetic Cement, Bistite II and Chemiace II were used to bond indirect resin disks to bovine dentin, as control, or coated by single-application or by dual-application of an adhesive system from ...

OBJECTIVE Evaluating the effect of resin coating and chlorhexidine on microleakage of two resin cements after water storage. MATERIALS AND METHODS Standardized class V cavities were prepared on facial and lingual surfaces of one hundred twenty intact human molars with gingival margins placed 1 mm below the cemento-enamel junction. Indirect composite inlays were fabricated and the specimens we...

The gas–liquid miscible backflow pumping seal (G-LMBPHS) is a non-contact mechanical that suitable for high-speed bearing chambers. However, the tribological properties and wear mechanisms of frictional pair G-LMBPHS in an oil–air environment have not yet been comprehensively studied. In this study, six pairs, consisting three hard materials (18Cr2Ni4WA, Al2O3 coating, Cr2O3 coating) two soft (...

introduction: resin cements are generally preferred for cementation of zirconia ceramics. resin bonding of zirconia ceramics cannot be done with the same methods of traditional ceramics because zirconia is a silica-free material. in recent years, many methods have been reported in the literature to provide the resin bonding of zirconia ceramics. the purpose of this in vitro study is to evaluate...

This work involves the development of a novel siliconized epoxy interpenetrating coating system using epoxy resin as base, hydroxylterminated polydimethylsiloxane (HTPDMS) as modifier, -aminopropyltriethoxysilane ( -APS) as crosslinking agent and dibutyltindilaurate (DBTDL) as catalyst. Polyamidoamine and aromatic polyamine adduct were used as curing agents for the above coating systems. The th...

This study was conducted to enhance the tensile bond strengths of resin cements to zirconia ceramics. Fifty-six zirconia ceramic specimens (Cercon Base) and twenty-eight silica-based ceramic specimens (GN-1, GN-1 Ceramic Block) were air-abraded using alumina. Thereafter, the zirconia ceramic specimens were divided into two subgroups of 28 each according to the surface pretreatment; no pretreatm...

Optical coherence tomography (OCT) is an interferometric imaging technique. This study aimed to employ OCT to evaluate four different resin-based materials including a coating containing glass-ionomer filler and calcium, a giomer, and two fluoride-releasing self-etch resins. The coating and its underlying and adjacent enamel were monitored using swept-source OCT (center wavelength: 1330 nm) at ...
