Effect of erosive challenges on deciduous teeth undergoing restorative procedures with different adhesive protocols - an in vitro study

J. appl. oral sci; 26 (), 2018
ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided acc...

TiF4 varnish protects the retention of brackets to enamel after in vitro mild erosive challenge

J. appl. oral sci; 26 (), 2018
Abstract The effect of fluoride agents on the retention of orthodontic brackets to enamel under erosive challenge is little investigated. Objective: The aim of this study was to evaluate the effect of titanium tetrafluoride (TiF4) and sodium fluoride (NaF) agents on the shear bond strength of brackets t...

Doxycycline-containing glass ionomer cement for arresting residual caries: an in vitro study and a pilot trial

J. appl. oral sci; 26 (), 2018
Abstract In a previous study, we demonstrated that the incorporation of doxycycline hyclate (DOX) into resin-modified glass ionomer cement (RMGIC) inhibited important cariogenic microorganisms, without modifying its biological and mechanical characteristics. In this study, we keep focused on the effect o...

Effects of experimental bleaching agents on the mineral content of sound and demineralized enamels

J. appl. oral sci; 26 (), 2018
Abstract High concentrations of hydrogen peroxide can cause adverse effects on composition and structure of teeth. However, the addition of calcium and fluoride in bleaching agents may reduce enamel demineralization. Objective: To evaluate chemical changes of sound and demineralized enamels submitted to...

Caries lesion remineralization with fluoride toothpastes and chlorhexidine - effects of application timing and toothpaste surfactant

J. appl. oral sci; 26 (), 2018
Abstract Habitual toothbrushing with fluoridated toothpaste followed by rinsing with antibacterial mouthwashes is a method to maintain good oral hygiene and to diminish the occurrence and severity of dental caries and periodontal disease. However, our understanding of how antimicrobial agents in mouthwas...

In vitro and in vivo evaluations of glass-ionomer cement containing chlorhexidine for Atraumatic Restorative Treatment

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: Addition of chlorhexidine has enhanced the antimicrobial effect of glass ionomer cement (GIC) indicated to Atraumatic Restorative Treatment (ART); however, the impact of this mixture on the properties of these materials and on the longevity of restorations must be investigated. The ...

Investigation on the biological effect of fluorine present on the surface of titanium implants: analysis of the reaction fluoride-titanium oxide

Actual. osteol; 13 (1), 2017
The aim of this work was to investigate the state of fluoride at the surface of fluoridemodified titanium implants, and to provide information to support or discard the hypothesis that fluoride ion participates in the osseointegration of implants. Titanium is coated with a 2-10 nm thick layer of stable a...

Osseointegration of titanium implants anodized with and without fluoride in the electrolyte: a study in rats

Actual. osteol; 13 (1), 2017
Based on the hypothesis that fluoride acts as a bone anabolic agent, the aim of this study was to measure in rats the osseointegration of implants (grade II titanium wire, 1 mm diameter, 4 mm long) submitted to anodic oxidation in 2 M phosphoric acid solution (control implants) or b) in 2 M phosphoric ac...

Effect of fluoride on salivary immunoglobulins and sialic acid

Summary Objective: The aim of our study was to evaluate the effect of fluoride on salivary immunoglobulin and sialic acid levels in children with dental fluorosis and healthy teeth who live in places with high fluoride concentration in drinking water. Method: Fifty-one (51) healthy children between 6 a...

Protective effect of milk against dental demineralization: understanding the mechanisms

This study aimed to answer the following questions: 1) does whole fluoridated milk protect more against enamel and dentin erosion than fat-free fluoridated milk? 2) does the protective effect of fluoridated milk against erosion follow a dose-response relationship? 3) is the treatment with whole or fat-fr...
