Alternativa estética ante la pérdida de piezas primarias en el sector anterior: resolución clínica

Rev. Círc. Argent. Odontol; 76 (226), 2018
La pérdida de piezas permanentes en el sector anterior sigue siendo una preocupación clínica en el tratamiento odontológico de niños y adolescentes. Es importante destacar que la pubertad y la adolescencia son etapas donde las relaciones con los pares son de suma importancia. Las restauraciones prot...

Comparison of the clinical effect of the adhesive strategies of universal adhesives in the treatment of non-carious cervical lesions: systematic review and meta-analysis

J. oral res. (Impresa); 7 (5), 2018
Objective: to compare, through a systematic review and a meta-analysis, the clinical effect of the adhesive strategies of universal adhesives (UA) in the treatment of non-carious cervical lesions (NCCLs). material and method: a search of the literature was carried out up to january 2018, in the biomedic...

Efeito da contaminação por saliva na resistência adesiva de braquetes cerâmicos utilizando uma resina ortodôntica hidrofílica

Introdução: Alguns fatores, como a presença de saliva, são capazes de influenciar a adesão do braquete ao dente durante o procedimento de colagem e podem causar falha da resistência adesiva. Objetivo: O objetivo deste estudo foi avaliar a resistência ao cisalhamento de braquetes cerâmicos orto...

Effect of dentin preparation mode on the bond strength between human dentin and different resin cements

Braz. dent. j; 29 (3), 2018
Abstract The aim was to evaluate the influence of different dentin preparation mode in the smear layer characteristics (SL), hybrid layer (HL), and microtensile bond strength (µTBS) to dentin with two resin cements. The occlusal dentin of 120 third molars was exposed. The teeth were divided into 4 group...

Can the application of multi-mode adhesive be a substitute to silicatized/silanized y-tzp ceramics?

Braz. dent. j; 29 (3), 2018
Abstract This study evaluated the effectiveness of a multi-mode adhesive (SBU-Scotch Bond Universal/3M) as a substitute for silica coating and silane application on the bonding of zirconia ceramics to resin cement. One-hundred and twenty sintered zirconia ceramic blocks (5 x 5 x 5 mm) were obtained, fini...

Polymerization shrinkage of bulk fill composites and its correlation with bond strength

Braz. dent. j; 29 (3), 2018
Abstract The present study aimed to evaluates polymerization shrinkage (PS) using microcomputed tomography (μCT) and microtensile bond strength (μTBS) in bulk fill composites (BFC) and conventional class I restorations as well as the correlation between these factors. Class I cavities (4 x 5 x ...

Evaluation of the prototype of a new bracket-positioning gauge

ABSTRACT Objective: The purposes of this study were to present a prototype of a bracket-positioning gauge, which makes vertical inclination of the instrument difficult, allowing a reduction of vertical bracket positioning error, and to test its accuracy in bracket positioning by groups of individuals w...

Feldspar ceramic strength and the reinforcing effect by adhesive cementation under accelerated aging

Braz. dent. j; 29 (2), 2018
Abstract This study evaluated the effect of the accelerated artificial aging (AAA) on feldspar ceramic strength and the reinforcing effect promoted by adhesive cementation with resin luting agent. One hundred twenty feldspar ceramic disks were obtained. Sixty disks were acid-etched, silanized, and coated...

Bond strength of experimental root canal sealers based on mta and butyl ethylene glycol disalicylate

Braz. dent. j; 29 (2), 2018
Abstract This study investigated the bond strength of two experimental root canal sealers based on MTA and butyl ethylene glycol disalicylate: MTAe and MTAe-HA. The reference materials used for comparison were AH Plus and MTA Fillapex. Twenty human upper incisors were selected and one 1 mm slice was obta...
