Evaluación clínica de barniz de flúor en el manejo de la hipersensibilidad dentinaria

La Hipersensibilidad Dentinaria (HD) se define como un corto y fuerte dolor generado por la exposición de dentina, que surge de un estímulo químico, térmico, táctil u osmótico, el cual no puede catalogarse como una patología dental propiamente tal. La teoría hidrodinámica de Brännström es la m...

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

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

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...

The anti-caries activity and toxicity of an experimental propolis-containing varnish

Abstract We investigated the anti-caries effects of an experimental propolis varnish in vivo, and further tested its toxicity against fibroblasts. Fifty-six SPF female Wistar rats were infected with Streptococcus mutans UA159 (SM) and allocated into four groups (n = 14/group): G1, propolis varnish (15%/P...

Effectiveness of a pre-procedural mouthwash in reducing bacteria in dental aerosols: randomized clinical trial

Abstract The aim of this randomized, single blinded clinical trial was to evaluate the effect of a pre-procedural mouthwash containing cetylpyridinium chloride (CPC), zinc lactate (Zn) and sodium fluoride (F) in the reduction of viable bacteria in oral aerosol after a dental prophylaxis with ultrasonic s...

AmF/NaF/SnCl2 solution reduces in situ enamel erosion - profilometry and cross-sectional nanoindentation analysis

Abstract This in situ study aimed to investigate the effect of a tin-containing fluoride solution in preventing enamel erosion. Also, its effects on the partly demineralized zone were assessed for the first time. Thirteen volunteers participated in this 2-phase study, wearing removable intra-oral applian...

Antimicrobial activity of ozone and NaF-chlorhexidine on early childhood caries

Abstract An early childhood carie (ECC) is an extremely destructive form of tooth decay. The aim of this study was to investigate the action of ozone (O3), and the association of sodium fluoride (NaF) with chlorhexidine (CHX) on bacteria related to ECC. Overnight culture of the bacteria was performed. On...

Survival of sealants in molars affected by molar-incisor hypomineralization: 18-month follow-up

Abstract The objective of this study was to evaluate the clinical survival of sealants applied in first permanent molars (FPMs) affected by molar-incisor hypomineralization (MIH), at 18 months of follow-up. Forty-one first permanent molars were selected from 21 children, 6–8 years of age. MIH was c...

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 (e...

Efficacy of two mouthwashes with cetylpyridinium chloride: a controlled randomized clinical trial

Abstract This study aimed to evaluate the anti-plaque and anti-gingivitis effects of two mouthwashes containing cetylpyridinium chloride (CPC), in comparison to negative control mouthwash. One hundred and twenty subjects were randomly assigned to study groups: test (0.075% CPC and 0.28% zinc lactate), po...
