Abstract We assessed the effect of a new coating material based on resin-modified glass-ionomer with calcium (Ca) in inhibiting the demineralization of underlying and adjacent areas surrounding caries-like lesions in enamel. The measures used were surface hardness (SH) and cross-sectional hardness (CSH)....

Fluoride release and uptake in enhanced bioactivity glass ionomer cement ("glass carbomer™") compared with conventional and resin-modified glass ionomer cements

Hasan, Ammar M. H. R; Sidhu, Sharanbir K; Nicholson, John W.

J. appl. oral sci; 27 (), 2019

Abstract Objectives To study the fluoride uptake and release properties of glass carbomer dental cements and compare them with those of conventional and resin-modified glass ionomers. Materials and Methods Three materials were used, as follows: glass carbomer (Glass Fill), conventional glass ionomer (C...

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

Medeiros, Maria Isabel Dantas de; Carlo, Hugo Lemes; Santos, Rogério Lacerda dos; Sousa, Frederico Barbosa; Castro, Ricardo Dias de; França, Renata Cristina Sobreira; Carvalho, Fabíola Galbiatti de.

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...

The use of sodium trimetaphosphate for matrix metalloproteinase inhibition, remineralization and bonding to dentin

Gonçalves, Rafael Simões.

The adhesive process to dentin substrate depends on the condition determined by the combined action of the mineral loss and the endogenous enzymes activity. Thus, considering a more complete therapeutic approach, sodium trimetaphosphate (STMP) may be a novel strategy that conciliates the remineralization...

Papel das proteases na erosão dentinária

Zarella, Bruno Lara.

Na dentina, a matriz orgânica desmineralizada tem um papel protetor contra desafios erosivos subsequentes. Porém, essa camada pode ser degradada por proteases, como as metaloproteinases da matriz (MMPs) e cisteína catepsinas (CCs). Recentemente, o uso de inibidores de proteases da matriz surgiu como u...

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...

Fluoride and sodium trimetaphosphate (TMP) release from fluoride varnishes supplemented with TMP

Manarelli, Michele Mauricio; Delbem, Alberto Carlos Botazzo; Percinoto, Célio; Pessan, Juliano Pelim.

Braz. oral res. (Online); 30 (1), 2016

Abstract This study assessed fluoride (F) and sodium trimetaphosphate (TMP) release into artificial saliva from varnishes containing 0%, 2.5%, and 5% NaF, supplemented or not with 5% TMP. The varnishes were applied on polyester sheets (n = 8/group), and F and TMP released into artificial saliva were meas...
