OBJECTIVE To study the effect of a low-shrinkage methacrylate monomer and monoacylphosphine oxide photoinitiator on color, translucency, and color stability of model resin-based composites (RBCs). METHODS Four micro-hybrid RBCs were prepared containing barium-glass fillers in bisphenol A-glycidyl-methacrylate (BisGMA) and triethyleneglycol-dimethacrylate(More)
OBJECTIVE The purpose of this study was to evaluate the elastic moduli of an unfilled adhesive resin (Adper Single Bond) and a filled adhesive resin (Adper Single Bond 2) used with and without a low-viscosity resin (LVR) (Filtek Flow) as an elastic cavity wall in class V composite restorations, restored with a hybrid resin composite (Z250). METHODS Buccal(More)
OBJECTIVES The purpose of this study was to evaluate how evaporation affects the shelf life of a one-bottle universal adhesive. METHODS Three different versions of Scotchbond Universal (SBU, 3M ESPE, Seefeld, Germany) were prepared using a weight-loss technique. SBU0 was left open to the air until maximal weight loss was obtained, whereas SBU50 was left(More)
OBJECTIVES To determine the effect of curing mode and restoration-surface pre-treatment on the micro-tensile bond strength (μTBS) to dentin. METHODS Sandblasted CAD/CAM composite blocks (LAVA Ultimate, 3M ESPE) were cemented to bur-cut dentin using either the etch & rinse composite cement Nexus 3 ('NX3', Kerr) with Optibond XTR ('XTR', Kerr), or the(More)
This study aimed to evaluate the effectiveness of various intermediate layers on the microleakage of Class V restorations under an occlusal load. Wedge-shaped cavities were prepared on the buccal surface of 72 extracted premolars, which were then treated with an adhesive system (One Up Bond F Plus), divided into three groups, and restored with: 1) Estelite(More)
OBJECTIVES To compare the degree of conversion (DC) of adhesives initiated by diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) or a camphorquinone/tertiary amine system (CQ/Amine) as well as their 'immediate' micro-tensile bond strength (μTBS) to bur-cut dentine. METHODS DC of Scotchbond Universal ('SBU'; 3M ESPE), its experimental counterpart(More)
UNLABELLED Today׳s most commonly applied bonding effectiveness tests are criticized for their high variability and low reliability, the latter in particular with regard to measuring the actual strength of the adhesive interface. OBJECTIVES in continuation of previous research conducted at dentin, we hereby aimed to validate the novel mini-interfacial(More)
Resin cement is commonly used for tooth restoration because of their physical and mechanical properties [1]. According to the mechanism of polymerization, this cement can be categorized into 3 types of self-cure, lightcure and dual-cure resin cement. Dual-cure resin cement is a system combining self-cure and lightcure polymerization mechanism together [2].(More)
PURPOSE To investigate the bonding efficacy of a multimode adhesive to plasma-treated and -untreated (control) dentin using a mini-interfacial fracture toughness (mini-iFT) test. MATERIALS AND METHODS Twenty human molars were used in a split-tooth design (n = 10). The adhesive Scotchbond Universal (SBU; 3M ESPE) was applied in etch-and-rinse (E&R) and(More)
