Abstract Objective The purpose of this study is to develop a quantitative structure–activity relationship (QSAR) model that can distinguish mutagenic from non-mutagenic species with <SPAN role=presentation tabIndex=0 id=MathJax-Element-3-Frame class=MathJax style="POSITION:…
Abstract Objectives The purpose of this study was to assess the surface roughness and morphology of three nanocomposites polished with two different polishing systems. Methods Specimens made of hybrid composite…
Abstract Objectives The development of different types of materials with application in dentistry is an area of intense growth and research, due to its importance in oral health. Among the…
The authors regret that on page e14 of this article the Washburn equation appeared incorrectly. The factor ‘rt’ in the Washburn equation should be in the numerator and not in…
Abstract Objective In this study three novel dimethacrylates of different chain lengths having bulky bicycloaliphatic rings were synthesized and proposed as possible dental monomers for dental resin mixtures. Methods The…
Abstract Objectives Resin-modified glass ionomers (RMGI) have demonstrated clinical success providing immediate and long-term relief from root sensitivity. RMGIs have been recently introduced as paste-liquid systems for convenience of clinical…
Abstract Objectives The purpose of the present investigation was to trace the fate of bisphenol A injected into pregnant mice, focusing on its potential accumulation in the fetus and the…
Abstract Objectives The aims of this investigation were to investigate dual-cured luting-agents as to whether their bond strength, dimensional change and flexural modulus influence no interfacial-gap incidence parameters of composite…
Abstract Objectives Determination of material and fractographic properties of a dental indirect resin composite material. Methods A resin composite (Paradigm, 3M-ESPE, MN) was characterized by strength, static elastic modulus, Knoop…
Abstract Objectives To optimize a microtomographic (micro-CT) technique to quantitatively evaluate the effectiveness of contemporary caries-excavation techniques. Methods A beam-hardening curve was obtained from an initial reconstruction of a wedge-shaped…
Abstract Objective Dentinal MMPs have been claimed to contribute to the auto-degradation of collagen fibrils within incompletely resin-infiltrated hybrid layers and their inhibition may, therefore, slow the degradation of hybrid…
Abstract Objective The aim of this investigation was to determine reaction enthalpy, ion viscosity and curing light transmission changes of unfilled methacrylate-based systems in order to compare methods that monitor…
Abstract Objective The Shore hardness test is a quick and convenient way to measure hardness of elastomers. The test specifies that the specimen should be at least 6 mm thick;…
Abstract Objectives The metastability of the tetragonal crystal structure of yttria partial stabilized zirconia polycrystalline (Y-TZP) ceramics is a basis of concern for dental restorations. Reactions between the porcelain and…
Abstract Objective To investigate the effect of indenter size on the failure mode of amalgam and its interaction with thickness. Methods Dental silver amalgam (Lojic+, SDI) discs, 10 mm diameter,…
Abstract Objectives To assess the bonding potential of a universal composite resin cement and an adhesive/composite system to differently pre-treated PEEK surfaces. Methods One hundred and fifty PEEK disks were…
Abstract Objectives The purpose of the study was to evaluate the influence of preparation design, and ceramic material, masticatory fatigue and fracture resistance of non-retentive all-ceramic full-coverage restorations luted on…
Abstract Objectives The low-shrinking composite composed of combined siloxane–oxirane technology (Filtek Silorane, 3M ESPE, Seefeld, Germany) required the development of a specific adhesive (Silorane System Adhesive, 3M ESPE), in particular…
Abstract With rapid advances in modern dentistry, high-energy output instruments ( e.g. , dental lasers and light polymerizing units) are increasingly employed in dental surgery for applications such as laser…
Abstract Objective This study evaluated the effects of different NaOCl concentrations and contact times on removal of the organic phase from mineralized dentin with and without the adjunctive use of…
