1. A systematic review of factors associated with the retention of glass fiber posts
This study aimed to identify factors that can affect the retention of glass fiber posts to intra-radicular dentin based on in vitro studies that compared the bond strength (BS) of GFPs cemented with resin cements. Searches were carried out in PubMed and Scopus until December 2013. Bond strength values and variables as type of tooth, presence of endodontic tr

2. Effect of composite surface treatment and aging on the bond strength between a core build-up composite and a luting agent
Objective The purpose of this study was to assess the influence of conditioning methods and thermocycling on the bond strength between composite core and resin cement. Material and Methods Eighty blocks (8×8×4 mm) were prepared with core build-up composite. The cementation surface was roughened with 120-grit carbide paper and the blocks were thermocycled

3. A castor oil-containing dental luting agent: effects of cyclic loading and storage time on flexural strength
Favorable results in the use of castor oil polyurethane (COP) as pulp capping, membrane material, sealer, mouthwash and in bone repair, associated with the fact that Ricinus communis is not derived from petroleum and it is abundant in Brazil, encourage researches in the development of luting agents. Objectives This study compared the flexural strength (FS

6. Análise de sistemas de fixação resinosos : por meio de nanoinfiltração, microdureza e microcisalhamento / Analisys of resin luting systems through nanoleakage
During the cementing indirect restorations procedure using resin luting systems, polymerization is essential for an effective clinical outcome of success. The aim of this in vitro study was to evaluate the Knoop hardness (KHN), microshear bond strength (MSBS) and nanoleakage pattern of resin cements and flowable resin to dental enamel. Ninety-two enamel bovi
