Innovative ablative fire resistant composites based on phenolic resins modified with mesoporous silica particles
(Elsevier, 2017-10)
Mesoporous silica particles were used as reinforcement of a phenolic resin to develop new ablative materials. A resol type phenolic resin was filled with mesoporous silica particles synthesized from tetraethyl orthosilicate ...
Effects of artificial staining on bulk-filled resin composites
(2018-06-01)
Purpose: To evaluate the color stability of bulk-fill resin composites (RC) in comparison to conventional RC submitted to artificial staining. Methods: 15 specimens of each RC were prepared. Five bulk-fill RC [X-tra Base ...

Minimization of polymerization shrinkage effects on composite resins by the control of irradiance during the photoactivation process
(Univ Sao Paulo Fac Odontologia Bauru, 2018-01-01)
High levels of shrinkage stress caused by volumetric variations during the activation process are one of the main problems in the practical application of composite resins. Objective: The aim of this study is to reduce the ...
