Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation

Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with t...

Adhesión posclareamiento y el efecto de la aplicación de antioxidantes
Postbleaching bonding and the effect of applying antioxidants

Con el avance en las técnicas de blanqueamiento dental, el advenimiento de nuevos biomateriales capaces de lograr resultados estéticos aceptables por los pacientes; sabiendo que en la operatoria dental muchos autores priorizan iniciar dicho tratamiento restaurador con el aclareamiento dental. Como cons...

J. appl. oral sci; 26 (), 2018
Abstract Objective The objective of this study was to evaluate the effects of combinations of silane primers and adhesive agents on the bond strength of a composite block for a computer-aided design and manufacturing system. Material and Methods Three silane primers [Clearfil Ceramic Primer (CP), Super...

TiF4 varnish protects the retention of brackets to enamel after in vitro mild erosive challenge

J. appl. oral sci; 26 (), 2018
Abstract The effect of fluoride agents on the retention of orthodontic brackets to enamel under erosive challenge is little investigated. Objective: The aim of this study was to evaluate the effect of titanium tetrafluoride (TiF4) and sodium fluoride (NaF) agents on the shear bond strength of brackets t...

Spectrophotometric assessment of tooth bleaching under orthodontic braquets bonded with different materials

Introduction: patients have been submitted to tooth bleaching during orthodontic treatment for aesthetic purposes or to anticipate the replacement of restorations after completion of the treatment. Objective: to evaluate the effectiveness of tooth bleaching under orthodontic brackets bonded with differe...

Effect of TiO2 nanoparticles incorporation on antibacterial properties and shear bond strength of dental composite used in Orthodontics

ABSTRACT Introduction: Plaque accumulation and bond failure are drawbacks of orthodontic treatment, which requires composite for bonding of brackets. As the antimicrobial properties of TiO2 nanoparticles (NPs) have been proven, the aim of this study was to evaluate the antimicrobial and mechanical prop...

Dentin pretreatment and adhesive temperature as affecting factors on bond strength of a universal adhesive system

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: To evaluate the effects of dentin pretreatment and temperature on the bond strength of a universal adhesive system to dentin. Material and Methods: Ninety-six extracted non-carious human third molars were randomly divided into 12 groups (n=8) according to Scotchbond Universal Adhes...

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...

Tooth fragment re-attachment in fracture with biological width violation: case

ABSTRACT: Dento-alveolar traumas are one of the most frequent injuries to teeth, mainly affecting the upper incisors due to their exposed position in the dental arch. In such cases, esthetics, function and phonetics of anterior teeth may be compromised. Furthermore, when there is involvement of the biolo...

Randomized clinical trials of dental bleaching - Compliance with the CONSORT Statement: a systematic review

Braz. oral res. (Online); 31 (supl.1), 2017
Abstract We reviewed the literature to evaluate: a) The compliance of randomized clinical trials (RCTs) on bleaching with the CONSORT; and b) the risk of bias of these studies using the Cochrane Collaboration risk of bias tool (CCRT). We searched the Cochrane Library, PubMed and other electronic database...
