The effect of standardised implantoplasty protocol on titanium surface roughness: an in-vitro study

Braz. oral res. (Online); 30 (1), 2016
Abstract: To analyse the changes of surface characteristics of machined and moderately roughened titanium disks following a standardised implantoplasty protocol. Forty titanium discs (machined: n = 20; moderately roughened: n = 20) were instrumented with one half of each disc maintained as the control (n...

Influence of different fillers on the properties of an experimental vinyl polysiloxane

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of the study was to evaluate the effect of the incorporation of different fillers on an experimental vinyl polysiloxane (VPS) at two different concentrations, 20% and 40%. Different fillers were added to an experimental VPS. The study was developed in two stages: (i) incorporation of fil...

Thickness and nanomechanical properties of protective layer formed by TiF4 varnish on enamel after erosion

Braz. oral res. (Online); 30 (1), 2016
Abstract The layer formed by fluoride compounds on tooth surface is important to protect the underlying enamel from erosion. However, there is no investigation into the properties of protective layer formed by NaF and TiF4 varnishes on eroded enamel. This study aimed to evaluate the thickness, topography...

In vivo performance of different scaffolds for dental pulp stem cells induced for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to determine the in vivo performance of three different materials as scaffolds for dental pulp stem cells (DPSC) undergoing induced odontogenic differentiation. An odontogenic medium modified by the addition of recombinant human bone morphogenetic protein 2 was used in th...

Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm

Braz. oral res. (Online); 30 (1), 2016
Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed...

Effects of modeling liquid/resin and polishing on the color change of resin composite

Braz. oral res. (Online); 30 (1), 2016
Abstract Modeling liquids/resins have been used to build up resin composite (RC) restorations, although there is a lack of information regarding their effects on the color stability of the latter. Therefore, the purpose of the present study was to evaluate the effects of the presence of modeling liquid b...

The effect of smoking on myeloid-related protein-8 and myeloid-related protein-14

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to determine the myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of smoker patients with generalized aggressive periodontitis (SAgP), smoker patients with chronic periodontitis (SCP), smoker patients with gingivitis (SG-s...

Biocompatibility and biomineralization assessment of bioceramic-, epoxy-, and calcium hydroxide-based sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract Obturation of the root canal system aims to fill empty spaces, promoting hermetic sealing and preventing bacterial activity in periapical tissues. This should provide optimal conditions for repair, stimulating the process of biomineralization. An endodontic sealer should be biocompatible once it...

Effect of irrigation technique for removal of triple antibiotic paste on bond strength of MTA to root dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 4...
