Abstract Objective: To assess the short-term effect of two in vitro erosive challenge protocols on the bond strength of metal orthodontic brackets on bovine enamel. Methods: Sixty bovine incisors were selected and randomly divided into six groups: AS7 (artificial saliva - 7 days, Control Group); CC7 (...

Abstract This study evaluated the effect of different hydrofluoric acid (HF) concentrations on the bond strength between a lithium disilicate-based glass ceramic and a resin cement. Eighty ceramic-blocks (12×7×2 mm) of IPS e.Max CAD (Ivoclar Vivadent) were produced and randomly assigned to 8 groups, co...

Objetivo: apresentar uma revisão de literatura sobreos tipos de tratamentos de superfície disponíveis paracimentação adesiva a sistemas cerâmicos. Revisãode literatura: ainda que haja certo consenso na uniãoadesiva às vitrocerâmicas, ainda não há uma unanimidadequanto à adesão de cerâmicas...
Abstract The aim of this study was to compare the bond strength (BS) of glass fiber posts (GFP) luted to oval and circular-shaped root canals rehabilitated using varying post techniques, at different intraradicular levels. Ninety 16-mm-long roots of human mandibular premolars, classified either as having...
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...
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...

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...

A colagem indireta pode ser definida como o posicionamento dos bráquetes ortodônticos em modelos, previamente à colagem clínica. A inclusão dos modelos digitais na ortodontia permite o planejamento virtual das posições dos acessórios ortodônticos. O objetivo deste estudo foi avaliar a acurácia ...
Abstract: Adhesive procedures have changed the way to restore endodontically treated teeth (ETT). It started with the shift from cast post-and-core to fiber post. The original focus on strength also shifted towards failure modes, revealing that catastrophic failures are still a concern when restoring end...
