Compressive strength of dental composites photo-activated with different light tips
(2013-04-01)
The aim of this study was to evaluate the compressive strength of microhybrid (Filtek™ Z250) and nanofilled (Filtek™ Supreme XT) composite resins photo-activated with two different light guide tips, fiber optic and polymer, ...
Comparison of different polishing methods on the surface roughness of microhybrid, microfill, and nanofill composite resins
(Wiley-Blackwell, 2018-02-01)
Aim: The aim of the present study was to evaluate the effect of different polishing methods on the surface roughness of resin-based composites subjected to a thermocycling procedure. Methods: A total of 192 specimens were ...
Effect of thermocycling on roughness of nanofill, microfill and microhybrid composites
(Informa Healthcare, 2015)
Effect of different finishing times on surface roughness and maintenance of polish in nanoparticle and microhybrid composite resins.
(2010-01-01)
The objective of the study was to evaluate the effect of immediate polishing, after 24 h and after 1 week, on the surface roughness of two micro-hybrid resins (Esthet-X; Opallis) and one nanoparticle resin (Filtek Z350), ...
Impact of filler size and distribution on roughness and wear of composite resin after simulated toothbrushing
(UNIV SAO PAULO FAC ODONTOLOGIA BAURUBAURU-SP, 2012)
Objectives: Nanofilled composite resins are claimed to provide superior mechanical properties compared with microhybrid resins. Thus, the aim of this study was to compare nanofilled with microhybrid composite resins. The ...
The effect of whitening toothpastes on colour change and surface roughness of restorative materials
(Facultad de Odontología. Universidad de Costa Rica, 2023)
Nanofilled bis-acryl composite resin materials: Is it necessary to polish?
(2020-01-01)
Statement of problem: Manufacturers of the recently introduced nanofilled bis-acryl composite resins no longer recommend polishing to produce interim restorations; however, whether this advice is appropriate is unclear. ...
Knoop microhardness and FT-Raman evaluation of composite resins: influence of opacity and photoactivation source
(Sociedade Brasileira de Pesquisa Odontológica, 2011)
The aim of this study was to evaluate the degree of conversion by Knoop microhardness (KHN) and FT-Raman spectroscopy (FTIR) of one nanofilled (Filtek Supreme-3M-ESPE [FS]) and one microhybrid composite (Charisma-Heraeus-Kulzer ...
