Rubbing time and bonding performance of one-step adhesives to primary enamel and dentin

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: This study investigated whether increasing the concentration of acidic monomers in one-step adhesives would allow reducing their application time without interfering with the bonding ability to primary enamel and dentin. Material and methods: Experimental one-step self-etch adhesiv...

Effects of porcelain thickness on the flexural strength and crack propagation in a bilayered zirconia system

J. appl. oral sci; 25 (5), 2017
Abstract Objective: This study evaluated the influence of porcelain (VM9, VITA Zahnfabrik, Germany) thickness on the flexural strength and crack propagation in bilayered zirconia systems (YZ, VITA Zahnfabrik, Germany). Material and Methods: Thirty zirconia bars (20.0x4.0x1.0 mm) and six zirconia blocks...

In vitro and in vivo evaluations of glass-ionomer cement containing chlorhexidine for Atraumatic Restorative Treatment

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: Addition of chlorhexidine has enhanced the antimicrobial effect of glass ionomer cement (GIC) indicated to Atraumatic Restorative Treatment (ART); however, the impact of this mixture on the properties of these materials and on the longevity of restorations must be investigated. The ...

Effect of 2 % chlorhexidine on dentin shear bond strength of different adhesive systems: a 6 months evaluation

Int. j. morphol; 35 (3), 2017
This study evaluated the effect of chlorhexidine dentin treatment on shear bond strength (SBS) of adhesive systems after different storages. The work included 144 third molars that had their dentin exposed and were divided in 6 groups: G1 (ASB+CHX: Adper Scotchbond 1XT + chlorhexidine 2 % prior Primer); ...

Degradación de la Fuerza de los Elásticos Intermaxilares de Látex y no Látex

RESUMEN: El propósito del presente estudio fue comparar la degradación de la fuerza entre los elásticos de látex y no látex de 3/16" y 6 oz. La muestra consistió en 30 elásticos por grupo e intervalo de tiempo haciendo un total de 180 elásticos de látex y 180 de no látex. Se midió la fuerza in...

Tensiometric analysis of meshes used in abdominal ventral wall defects in rats

ABCD (São Paulo, Impr.); 30 (3), 2017
ABSTRACT Background: Among the various strategies to avoid exaggerated foreign body reaction in the treatment of hernias is the limitation of the amount of polypropylene or the use of absorbable material. Aim: To evaluate the healing of defects in the abdominal wall of rats, comparing microporous polyp...

Microtensile Bond Strength of Adhesive Systems in Different Dentin Regions on a Class II Cavity Configuration

Braz. dent. j; 28 (4), 2017
Abstract The aim of this study was to evaluate microtensile bond strength (µTBS) of self-etch and etch-and-rinse adhesives systems compared in different dentin regions (central-CD or proximal-PD) in a class II cavity configuration. A class II (mesial-oclusal-distal) cavity configuration was simulated on...

Bond strength and adhesive remnant index of experimental brackets bonded with self-adhesive resin cement

ABSTRACT: Aim: To evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) of experimental brackets bonded with self-adhesive resin cement. Ninety bovine teeth were randomly distributed (n = 15) according to the groups: G1 - metal brackets bonded with Transbond™ XT; G2 - APC metal b...

Effect of surface treatment of prefabricated teeth on shear bond strength of orthodontic brackets

ABSTRACT Objective: The aim of this in vitro study was to evaluate and compare the effects of grinding, drilling, sandblasting, and ageing prefabricated teeth (PfT) on the shear bond strength (SBS) of orthodontic brackets, as well as the effects of surface treatments on the adhesive remnant index (ARI)...

Evaluation of physicochemical properties of root-end filling materials using conventional and Micro-CT tests

J. appl. oral sci; 25 (4), 2017
Abstract Objective To evaluate solubility, dimensional stability, filling ability and volumetric change of root-end filling materials using conventional tests and new Micro-CT-based methods. Material and Methods Solubility (loss of mass) after 7 and 30 days, and dimensional stability (in mm) were eva...
