13. Preventive effect of toothpastes with MMP inhibitors on human dentine erosion and abrasion in vitro
ABSTRACT The use of gels and mouthrinses with MMP inhibitors (chlorhexidine, and green tea extract) was shown to prevent erosive wear. The aim of this study was to analyze the protective effect of toothpastes containing MMP inhibitors on dentine loss induced by erosion in vitro. Material and Methods Five groups each containing 12 specimens of human root de

15. Choice of toothpaste for the elderly: an in vitro study
Hyposalivation and dental root exposure in the elderly are problems that require special oral care. In this context, the characteristics of certain toothpastes are of particular importance. Thus, the aim of this study was to evaluate the cytotoxicity and dentin wear caused by seven different toothpastes. For dentin wear analysis, 40 root dentin specimens wer

17. Evidence-based recommendation on toothpaste use
Toothpaste can be used as a vehicle for substances to improve the oral health of individuals and populations. Therefore, it should be recommended based on the best scientific evidence available, and not on the opinion of authorities or specialists. Fluoride is the most important therapeutic substance used in toothpastes, adding to the effect of mechanical to

19. Abrasion of 6 dentifrices measured by vertical scanning interference microscopy
OBJECTIVES: The abrasion of dentifrices is well recognized to eliminate the dental plaque. The aims of this study were to characterize the abrasive powders of 6 dentifrices (3 toothpastes and 3 toothpowders) and to measure the abrasion on a test surface by Vertical Scanning Interference microscopy (VSI). MATERIAL AND METHODS: Bright field and polarizatio

22. Effect of whitening toothpaste on titanium and titanium alloy surfaces
Dental implants have increased the use of titanium and titanium alloys in prosthetic applications. Whitening toothpastes with peroxides are available for patients with high aesthetic requirements, but the effect of whitening toothpastes on titanium surfaces is not yet known, although titanium is prone to fluoride ion attack. Thus, the aim of the present stud

23. Fast direct determination of titanium dioxide in toothpastes by X-Ray fluorescence and multivariate calibration
Recentemente, o dióxido de titânio foi classificado como potencialmente carcinogênico pela International Agency for Research on Cancer (IARC). Dióxido de titânio é um pigmento geralmente utilizado como opacificante em cremes dentais, porém sua concentração não é indicada nos rótulos dos produtos. Neste estudo, 22 amostras de cremes dentais foram

24. Fluoride concentration in the top-selling Brazilian toothpastes purchased at different regions
Para ter relevância em termos de saúde pública, os cremes dentais amplamente utilizados pela população devem ter fluoreto (F) solúvel numa concentração mínima de 1.000 ppm F. Assim, as concentrações de fluoreto total (FT) e flureto solúvel total (FST) nos cremes dentais mais vendidos no Brasil foram avaliados. Os cremes dentais (n=3) Colgate Anti
