Distribution of 14C-bisphenol A in pregnant and newborn mice
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…
Physical properties of dual-cured luting-agents correlated to early no interfacial-gap incidence with composite inlay restorations
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…
Material properties and fractography of an indirect dental resin 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…
Micro-CT based quantitative evaluation of caries excavation
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…
Use of a specific MMP-inhibitor (galardin) for preservation of hybrid layer
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…
Dynamic monitoring of curing photoactive resins: A methods comparison
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…
An experimental and theoretical study of the effect of sample thickness on the Shore hardness of elastomers
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;…
XRD 2micro-diffraction analysis of the interface between Y-TZP and veneering porcelain: Role of application methods
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…
Interactive effect of indenter size and specimen thickness in Hertzian indentation test
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,…
Effect of different surface pre-treatments and luting materials on shear bond strength to PEEK
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…
