Full-text available
Objectives: The physical properties of dental restorative materials have a crucial effect on the longevity of restorations and moreover on the esthetic demands of patients, but they may be compromised by bleaching treatments. The purpose of this study was to evaluate the effects of in-office bleaching agents on the physical properties of three com...

The optical properties of dental restorative materials have a dramatic effect on patient esthetics, which may be compromised by the poor blending effect of composites resins at the composite-tooth interface. The objective of this study was to evaluate the color-matching ability and the blending effects of 3 different composite resins when restoring...

Statement of problem: Monomer leaching from restorations may affect the oral mucosa and general health; however, information on monomer leaching from chairside computer-aided design and computer-aided manufacturing (CAD-CAM) restorative materials is lacking. Purpose: The purpose of this in vitro study was to investigate the leaching of monomers...

Aim: Crowns are applicable on primary teeth with extensive caries, cervical decalcification, developmental defects, interproximal caries extending beyond line angles, and following pulpotomy or pulpectomy. Background: Until now, prefabricated crowns, i.e., stainless-steel crowns (SSCs), pre-veneered SSC, and all ceramic/porcelain/zirconia crowns...

Objectives This study aimed to evaluate the optical properties of highly translucent 5 mol% yttria, partially stabilised monolithic zirconia, and 3 mol% yttria-stabilised tetragonal zirconia after their subjection to different milling methods and artificial ageing. Methods Two types of pre-shaded zirconia materials were used: inCoris TZI C and Kat...

Impurities or degradation of the components of resin-based materials have been throughout investigated by the dental scientific community. The aim of this study is to examine if there is a release of monomers from resin-based materials when they are immersed in common beverage materials which are consumed by the population in large quantities. Thre...
Article
The main objective of this research was to detect monomers that are released during dental restorative procedures related to the oral cavity and then discharged into the environment through the drainage of the dental unit. This study involves the collection of wastewater from the spray system of a high-speed dental handpiece before it winds up in t...
Article
Purpose: The purpose of this study was to evaluate the leaching pattern of different types of polymer computer-aided design and computer-aided manufacturing (CAD-CAM) materials with a conventional resin composite. Methods and materials: Specimens of three representatives by type of polymer CAD-CAM blocks and one conventional resin composite were...
Article
Recently, self-adhesive flowable composite resins (SAFC) have been introduced to dental practice to simplify the clinical procedure and to reduce the treatment time but with limited data regarding their bonding performance to dentin. The aim of this in vitro study was to evaluate the micro-shear bond strength (μ-SBS) of a giomer SAFC (FIT SA F03 –...
Article
A rapid and simple fabric phase sorptive extraction (FPSE) procedure is developed for the simultaneous extraction of four monomers (Bisphenol A, BPA; Triethylene glycol dimethacrylate, TEGDMA; Urethane dimethacrylate, UDMA; Bisphenol A-glycidyl methacrylate, BisGMA) in human saliva, prior to the determination by high pressure liquid chromatography...

Purpose: The aim of this in vitro study was to examine the effect of Er,Cr:YSGG laser-assisted tooth bleaching treatment on the elution of monomers and surface roughness of a hybrid computer-aided design-computer-aided manufacturing (CAD-CAM) material, and to compare it with a resin composite for direct restorations. Methods and materials: Forty...

Bisphenol-A (BPA), bisphenol A glycerolate dimethacrylate (Bis-GMA), triethylene glycol dimethacrylate (TEGDMA), and urethane dimethacrylate (UDMA) are organic monomers that can be released from dental composites into the oral cavity. Over specific concentrations, they can act as endocrine disruptors or cause toxic effects. The purpose of this work...
Article
An HPLC method was applied to evaluate the inhibiting effect of phosphate buffer on the leaching pattern of resin composites and the significance of pH levels during the storage period in the solutions. Ten (10) disk-shaped specimens (2 mm × 12 mm diameter) from Evetric restorative resin composite were immersed by means of a silk string in each of...
Article
A high-performance liquid chromatographic method was applied to evaluate the effect of bicarbonate (NaHCO3) and phosphate (NaH2PO4, Na2HPO4) buffers on monomer leachability of dental resin composites. Evetric was the restorative resin composite that was investigated in current study. Forty disk-shaped resin composite specimens (n = 40) were immerse...
Article
Full-text available
Aim: Color matching of the restoration to the adjacent teeth can be difficult due to the translucency of the ceramic and the visual exposure of the polymerized resin cement through the ceramic material. The aim of this study was to identify color differences between try-in pastes and the corresponding luting resin composites. Materials and method...
Conference Paper
Full-text available
Purpose: Degradation of resin composites in the oral environment is associated to the release of chemicals which are potentially harmful. Bisphenol A (BPA) is a suspected endocrine disrupting compound with the chemical formula (CH 3)2C(C 6 H 4 OH) 2 belonging to the group of diphenylmethane derivatives and bisphenols. The purpose of this study was...
Conference Paper
Full-text available
Objectives: Resin-based composite cements are the materials of choice for the adhesive luting of all-ceramic crowns and laminate porcelain veneers (LPV). Usually, water soluble, glycerin-based try-in pastes are used prior to final cementation to allow the shade of the restoration to be simulated. These pastes should feature the same optical propert...
Conference Paper
Objectives: Effect of dental bleaching procedures on colour stability of resin restorative materials remains questionable. The aim of this study was to evaluate the quantitative colour changes that occurred in restorative materials after in-office bleaching with 30% carbamide peroxide and 36% hydrogen peroxide in vitro. Methods: Forty specimens wer...
Article

The surface roughness of dental restorative materials has a crucial effect on the health of dental and periodontal tissues as well as for the longevity of restorations. In this study we tested a glass ionomer restorative cement, two nanohybrid resin composites, a flowable resin composite and a silorane-based composite. Twenty cylindrical specimens...
Article

Objectives: The surface roughness of restorative materials is an important factor for the esthetic appearance and longevity of restorations. The presence of irregularities on the surface may result in plaque and stain retention, periodontal inflammation, and solubility of the organic matrix. During periodontal therapy sonic tips may inadvertently o...
