1. Remineralizing effect of commercial fluoride varnishes on artificial enamel lesions
Abstract: The aim of this study was to evaluate soluble and insoluble fluoride concentrations in commercial varnishes, and their remineralization effect on artificial caries enamel lesions using surface and cross-sectional microhardness evaluations. Forty bovine enamel blocks were separated into four groups (n=10): control (no treatment), Enamelast (Ultraden

2. TiF4 varnish protects the retention of brackets to enamel after in vitro mild erosive challenge
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 to enamel and on the enamel microhardness around bracket

3. In situ effect of titanium tetrafluoride varnish on enamel demineralization
Abstract The effect of a 4% titanium tetrafluoride (TiF 4 ) varnish on enamel demineralization was evaluated. Twelve volunteers participated in this double-blind, randomized crossover study. Six enamel specimens were positioned in intraoral appliances throughout four treatment stages: 4% TiF 4 varnish (experimental varnish), 5% sodium fluoride (NaF) varnish

4. Fluoride Varnishes against Dental Erosion Caused by Soft Drink Combined with Pediatric Liquid Medicine
Resumo O presente estudo avaliou o efeito dos vernizes de NaF e CPP-ACP/NaF na redução da erosão promovida por refrigerante e associada a um medicamento líquido pediátrico. Os espécimes de esmalte foram pré-tratados com verniz fluoretado, de acordo com o grupo de alocação: verniz NaF (Duraphat®) ou verniz CPP-ACP NaF (verniz MITM). Dois tipos disti

5. Thickness and nanomechanical properties of protective layer formed by TiF4 varnish on enamel after erosion
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, nanohardness, and elastic modulus of the protective l

6. Fluoride and sodium trimetaphosphate (TMP) release from fluoride varnishes supplemented with TMP
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 measured for up to 24 hours. The amount of F and TMP releas

7. Effect of 10% fluoride on the remineralization of dentin in situ
ABSTRACT Objective The purpose of this randomized, cross-over, in situ study was to determine the remineralization of demineralized dentin specimens after the application of a 10% fluoride (F-) or a 1% chlorhexidine–1% thymol (CHX–thymol) varnish. Material and Methods Twelve individuals without current caries activity wore removable appliances in the

8. Fluoride varnishes with calcium glycerophosphate: fluoride release and effect on in vitro enamel demineralization
The aims of this study were (1) to assess the amount of fluoride (F) released from varnishes containing calcium glycerophosphate (CaGP) and (2) to assess the effect of the experimental varnishes on in vitro demineralization. Six test groups using 5 varnishes: base varnish (no active ingredients); Duraphat® (2.26% NaF); Duofluorid® (5.63% NaF/CaF2); experim

9. TiF4 and NaF varnishes as anti-erosive agents on enamel and dentin erosion progression in vitro
Objective This study assessed the effect of fluoride varnishes on the progression of tooth erosion in vitro. Material and Methods: Forty-eight enamel and 60 root dentin samples were previously demineralized (0.1% citric acid, pH 2.5, 30 min), leading to a baseline and erosive wear of 12.9 and 11.4 µm, respectively. The samples were randomly treated (6 h) w

11. Evaluation of fluoride release from experimental TiF4 and NaF varnishes in vitro
Fluoride varnishes play an important role in the prevention of dental caries, promoting the inhibition of demineralization and the increase of remineralization. Objective: This study aimed to analyze the amount of fluoride released into water and artificial saliva from experimental TiF4 and NaF varnishes, with different concentrations, for 12 h. Materia

12. Desensitizing treatments for dentin hypersensitivity: a randomized, split-mouth clinical trial
The aim of this randomized, controlled, split-mouth, clinical study was to differentiate and clinically qualify the effectiveness of different desensitizing agents in the treatment of painful symptoms caused by cervical dentin hypersensitivity (CDH). Two hundred-and-fifty-two teeth of 42 patients were distributed into seven groups (n = 36): G1 - placebo; G2,
