Incorporation of silver nanoparticles into composite resins is recommended for their reported antibacterial properties, but this incorporation can affect the wettability of such materials. Therefore, this study evaluated the effect of nano-silver addition to silorane-based and methacrylate-based composites on their contact angle. Nano-silver particles were added to Z250 (methacrylate-based) and...
Resin Composites Sandwich restorations and Curing techniques Anders Lindberg, Department of Dental Hygienist Education, Faculty of Medicine, Umeå University, 901 87 Umeå, Sweden. Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing dema...
OBJECTIVE The purpose of this study was to analyze the shear bond strength of a new composite resin to polymer-based composite substrates using various surface roughnesses and two kinds of polymer matrices. MATERIALS AND METHODS Particulate filler composite resin with cross-linked polymer matrix and fiber-reinforced composite with semi-interpenetrating polymer matrix were used as bonding subs...
OBJECTIVES To assess the effect of lactic acid (LA) on microleakage of silorane-based composite restorations and methacrylate-based composites with self-etch and etch-and-rinse bonding systems. MATERIALS AND METHODS Class V cavities were prepared in 120 extracted human teeth, divided into four groups and restored as follows: 1. Silorane-based composite+P90 adhesive system (P90); 2. Filtek Z25...
Effect of ultraviolet light irradiation on bonding of experimental composite resin artificial teeth.
The purpose of the present study was to evaluate how ultraviolet light (UV) irradiation using an ordinary UV sterilizer would affect the bonding of experimental composite resins to an autopolymerizing acrylic resin. To this end, three composite resins and one unfilled resin--of which the compositions were similar to commercial composite resin artificial teeth--were prepared as repair composites...
OBJECTIVES This study aimed to assess the effect of 38% carbamide peroxide on the microleakage of class V cavities restored with either a silorane-based composite or two methacrylate-based composites. MATERIALS AND METHODS A total of 96 class V cavities were prepared on the buccal surface of extracted human teeth with both enamel and dentin margins and were randomly assigned into three groups...
Purpose: Evaluating effects of Nd:YAG-laser, Er:YAG-laser, chlorhexidine and ozonated water application which is used for purpose antibacterial effects, on repair bond strength silorane based composite. Materials Methods: 100 cavities (2 mm deep, 3 diameter) prepared in acrylic blocks were filled with composite subjected thermal cycle divided into 5 groups (N=20). Group 1:Chlorhexidine; 2:Ozona...
