Wear test combining simulated occlusal wear and toothbrush wear.
A new wear testing system, which carries out toothbrush wear and simulated occlusal wear tests alternately, was developed. Differences in wear behavior among three modes of wears, combined wear, toothbrush wear and simulated occlusal wear, were investigated using polymethylmethacrylate (PMMA) and two commercial resin composites (Z100, APX). The area of the material loss after each test was meas...
متن کاملWear of opposing teeth by posterior composite resins--evaluation of newly developed wear test methods.
In the present study, enamel wear against indirect composite resins was evaluated using two newly designed wear test methods: a rotating sliding wear test and a buff wear test. For the composite resins investigated in this study, their surface morphologies were examined using a scanning probe microscope after buff-polishing. After the wear tests, enamel was worn down by hard fillers that protru...
متن کاملEffects of abrasive and fiber components in medium on wear of composite resins.
Effects of abrasive and fiber components in a medium on the wear behavior of composite resins were evaluated. Calcium diphosphate and methyl cellulose were included in the medium as abrasive and fiber components respectively. A range of 0, 4, or 8% abrasive- or fiber-containing media were applied on a composite resin specimen during a simulated occlusal wear test. Four composite resins, Clearfi...
متن کاملEffects of toothbrush hardness on in vitro wear and roughness of composite resins.
AIM To investigate and compare the effects of toothbrushes with different hardness on abrasion and surface roughness of composite resins. MATERIALS AND METHODS Toothbrushes (DENT. EX Slimhead II 33, Lion Dental Products Co. Ltd., Tokyo, Japan) marked as soft, medium and hard, were used to brush 10 beam-shaped specimens of each of three composites resins (Venus [VEN], Venus Diamond [VED] and V...
متن کاملThe in vivo wear resistance of 12 composite resins.
PURPOSE The in vivo wear resistance of 12 composite resins were compared with an amalgam control using the Latin Square experimental design. Sixteen edentulous patients wearing specially designed complete dentures formed the experimental population. MATERIALS AND METHODS The Michigan Computer Graphics Measurement System was used to digitize the surface of the control and composite resin sampl...
