Influência da erosão dentária na adesão de braquetes ortodônticos colados ao esmalte com diferentes materiais

O diagnóstico das lesões incipientes de erosão em esmalte é difícil de ser realizado e, em situações clínicas, poderá ocorrer a colagem de braquetes em superfícies erodidas. Este trabalho in vitro avaliou a adesão de braquetes ortodônticos ao esmalte dentário bovino hígido e previamente ero...

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...

Effect of irrigation technique for removal of triple antibiotic paste on bond strength of MTA to root dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 4...

Push-out bond strength of MTA HP, a new high-plasticity calcium silicate-based cement

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to investigate the resistance to dislodgment provided by MTA HP, a new high-plasticity calcium silicate-based cement. Biodentine and White MTA Angelus were used as reference materials for comparison. Three discs 1 ± 0.1 mm thick were obtained from the middle third of the...

Root filling bond strength using reciprocating file-matched single-cones with different sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using o...

Effect of root canal filling techniques on the bond strength of epoxy resin-based sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the effects of different root canal filling techniques on the bond strength of epoxy resin-based sealers. Sixty single-rooted canines were prepared using ProTaper (F5) and divided into the following groups based on the root filling technique: Lateral Compact...

Drying protocol influence on the bond strength and apical sealing of three different endodontic sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the influence of drying protocols (DP) on the apical sealing (AS) and on the bond strength (BS) of teeth filled with different sealers. The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files (R50). Th...

Survival analysis of banding and bonding molar tubes in adult patients over a 12-month period: a split-mouth randomized clinical trial

Braz. oral res. (Online); 30 (1), 2016
Abstract: This split-mouth randomized clinical trial aimed to compare the survival rate of bonding and banding molar tubes in adult orthodontic patients. Eligibility criteria included adults (aged >18 years), no active caries, restorations, or fractures in the upper and lower molars. The main outcome ...

Is the ethanol wet-bonding technique a promising one?

The ethanol wet-bonding technique (EWBT) was introduced in an attempt to overcome the problems caused by high hydrophilicity and/or incomplete penetration of most commercially available adhesive systems. This strategy provides better conditions for the inter-diffusion of hydrophobic dentin monomers. Toda...

Evaluación de la interfase adhesiva obtenida en restauraciones de resina compuesta realizadas con un sistema adhesivo universal utilizado con y sin grabado ácido previo

OBJETIVO El propósito de esta investigación fue realizar un estudio observacional in vitro, al microscopio electrónico de barrido, de la interfase adhesiva diente-restauración lograda al utilizar un sistema adhesivo universal (Single Bond Universal®, 3M/ESPE, Alemania), con grabado ácido previo y c...
