Tissue dissolution and modifications in dentin composition by different sodium hypochlorite concentrations

J. appl. oral sci; 24 (3), 2016
ABSTRACT Sodium hypochlorite (NaOCl) remains the most used irrigation solution during root canal preparation because of characteristics such as wide-spectrum antimicrobial activity and organic tissue dissolution capacity. However, these solutions can alter dentin composition and there is no consensus on ...

Corrosion behavior of zirconia in acidulated phosphate fluoride

J. appl. oral sci; 24 (1), 2016
ABSTRACT Objective The corrosion behavior of zirconia in acidulated phosphate fluoride (APF) representing acidic environments and fluoride treatments was studied. Material and Methods Zirconia rods were immersed in 1.23% and 0.123% APF solutions and maintained at 37°C for determined periods of time....

Dissolution of a mineral trioxide aggregate sealer in endodontic solvents compared to conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study is to evaluate the solubility of a Mineral Trioxide Aggregate sealer (MTA-Fillapex) compared with five other sealers, calcium hydroxide (Sealapex), resin (Realseal), zinc oxide-eugenol (Tubli-Seal), and two epoxy resins (AH-26 and AH-Plus), in chloroform and eucalyptoil in ...

Six-month color change and water sorption of 9 new-generation flowable composites in 6 staining solutions

Braz. oral res. (Online); 30 (1), 2016
Abstract Color match and water sorption are two factors that affect restorative materials. Discoloration is essential in the lifespan of restorations. The aim of this study was to evaluate color change and water sorption of nine flowable composites at multiple time points over 6 months. 60 samples of eac...
