Relined fiberglass post: an ex vivo study of the resin cement thickness and dentin-resin interface

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the thickness of resin cements in the root thirds when using conventional fiberglass posts (CP) and relined fiberglass posts (RP) in weakened roots and to evaluate the morphological characteristics of the dentin-resin interface. Forty human maxillary anterio...

Optimizing light-cured composite through variations in camphorquinone and butylhydroxytoluene concentrations

Braz. oral res. (Online); 30 (1), 2016
Abstract The use of a free-radical polymerization inhibitor, butylhydroxytoluene (BHT), and a common photo-initiator, camphorquinone (CQ), to reduce polymerization stress in dental composite was investigated in this study. Samples were prepared by mixing Bis-GMA, UDMA, and TEGDMA at a 1:1:1 ratio (wt%), ...

Effect of endodontic sealer and resin luting strategies on pull-out bond strength of glass fiber posts to dentin

Acta odontol. latinoam; 23 (3), 2010
The aim of this study was to evaluate the influence of eugenolcontaining endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha o...

Avaliação in situ do efeito remineralizador de um selante resinoso e de um cimento de ionômero de vidro aplicados em esmalte dental bovino desmineralizado, associados a um verniz fluoretado

O presente trabalho teve como objetivo avaliar, in situ, o efeito remineralizador de um selante resinoso e um cimento de ionômero de vidro aplicados em esmalte dental bovino desmineralizado, associados a um verniz fluoretado. Para tal, 120 blocos de esmalte bovinos (4x4x2,5mm), previamente polidos e des...
