The effect of reduced glutathione on the toxicity of silver diamine fluoride in rat pulpal cells

J. appl. oral sci; 29 (), 2021
Abstract Introduction Due to its ability to arrest untreated dental caries, silver diamine fluoride (SDF) has been advocated for indirect pulp capping procedures. However, the high concentrations of silver and fluoride in SDF raise concerns about its biocompatibility to pulpal tissues. Objectives Thi...

Fluoride Concentration in SDF Commercial Products and Their Bioavailability with Demineralized Dentine

Braz. dent. j; 31 (3), 2020
Abstract The aim of this in vitro study was to determine the fluoride concentration in silver diamine fluoride (SDF) products and their bioavailability with demineralized dentine. The products evaluated (expected fluoride concentrations) were: I: Saforide 38% (45,283 ppm F); II: Advantage Arrest 38.3 to ...

Resistência aos compostos de amônio quaternário (QACs) de uso doméstico e hospitalar em patógenos prioritários multirresistentes

Compostos de amônio quaternário (QACs) têm sido amplamente utilizados como desinfetantes e antissépticos, sendo essenciais na prevenção e controle de infecções bacterianas na medicina humana e veterinária. Embora patógenos prioritários multirresistentes têm sido muito bem caracterizados quant...

Antifungal efficiency of chemically and thermally-activated acrylic resins after surface treatment using poly (diallyldimethylammonium chloride)

Abstract INTRODUCTION: Acrylic resins are used in the preparation of facial prostheses and may be colonized by fungi. Here, we verified the antifungal efficacy of this material after surface treatment using poly (diallyldimethylammonium chloride). METHODS: Acrylic resin specimens with and without surfa...

Use of green fluorescent protein labeled non-tuberculous mycobacteria to evaluate the activity quaternary ammonium compound disinfectants and antibiotics

Braz. j. microbiol; 48 (1), 2017
Abstract Although infections with NonTuberculous Mycobacteria have become less common in AIDS patients, they are important opportunistic infections after surgical procedures, likely because they are ubiquitous and not efficiently killed by many commonly used disinfectants. In Venezuela there have recentl...
