Influência do escoamento estático (CREEP) na dureza do amálgama. Efeito de ligas e regióes de medida.
(1990-05-01)
The authors studied the CREEP of 5 amalgam alloys (1 conventional and 4 with high cooper) by the application os static load of 36 MPa in 478 mm specimens, 7 days old. After CREEP test, the samples were included in acrylic ...

The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
Chemical analysis and Vickers hardness of orthodontic mini-implants
(Faculdade de Odontologia de Piracicaba - UNICAMP, 2015)
Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009)
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...
Effects of light exposure time on composite resin hardness after root reinforcement using translucent fibre post
(ELSEVIER SCI LTD, 2008)
Objectives: The purpose of this in vitro study was to evaluate the Vickers hardness (VHN) of a Light Core (Bisco) composite resin after root reinforcement, according to the light exposure time, region of intracanal ...
Avaliação da dureza superficial de resinas compostas para dentes posteriors
(2007-12-01)
The aim of this work in vitro was to evaluate the superficial hardness of four resin based composites used for restoration of posterior teeth (Point4/Kerr, Z250/3M Espe, Z100/3M Espe and P60/ 3M Espe). Vickers hardness was ...
