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

14. Effect of Brushing Time and Dentifrice Abrasiveness on Color Change and Surface Roughness of Resin Composites
Resumo: A abrasividade do dentifrício e o tempo de escovação podem aumentar a alteração de cor (∆E) e rugosidade de superfície (∆Ra) das resinas compostas. Este estudo teve como objetivo avaliar o efeito do tempo de escovação mecânica com dentifrícios de diferentes abrasividades, sobre o ∆E e a ∆Ra das resinas compostas (nanoparticulada, Z3

15. Efficacy of a triclosan formula in controlling early subgingival biofilm formation: a randomized trial
The aim of this study was to determine the efficacy of rinses with slurries of a dentifrice containing triclosan (TCS), as compared with rinses with slurries from a control dentifrice, in controlling early subgingival biofilm formation. A double-blind, randomized and cross-over clinical trial was designed, and 26 dental students were included. In the first p

16. Fluoride stability in dentifrices stored in schools in a town of northern Brazil
The aim of this study was to analyze fluoride stability in dentifrices stored during nine months in schools from Careiro da Várzea, State of Amazonas, Brazil. Analysis of total fluoride concentration, total soluble fluoride, and ionic fluoride in the dentifrice samples was performed in four different time periods: at the time of purchase (baseline); after t

17. Fluoride retention in saliva and in dental biofilm after different home-use fluoride treatments
This single-blind, randomized, crossover study aimed at assessing the long-term fluoride concentrations in saliva and in dental biofilm after different home-use fluoride treatments. The study volunteers (n = 38) were residents of an area with fluoridated drinking water. They were administered four treatments, each of which lasted for one week: twice-daily pl

19. Use of dentifrices to prevent erosive tooth wear: harmful or helpful?
Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing. Dentifrices containing different active agents may be helpful in allowing rehardening or in increasing surface resistance to further acidic or mechanical impacts. However, dent

20. In situ protocol for the determination of dose-response effect of low-fluoride dentifrices on enamel remineralization
No in situ protocol has assessed the dose-response effects of fluoride dentifrices involving low-fluoride formulations. Objective: To assess the ability of an in situ remineralization model in determining dose-response effects of dentifrices containing low fluoride concentrations ([F]) on bovine enamel. Material and Methods: Volunteers wore palatal ap

21. The influence of desensitizing dentifrices on pain induced by in-office bleaching
The purpose of this study was to evaluate whether the use of desensitizing dentifrices used 15 days prior to and after in-office tooth bleaching could eliminate or reduce tooth sensitivity. After institutional review board approval and informed consent, 45 subjects were selected and divided into 3 groups according to the dentifrice selected: Colgate Total (C

22. Effect of a desensitizing dentifrice on the bond strength of different adhesive systems
AIM: This in vitro study evaluated the effect of using a dental hypersensitivity treatment on the bond strength to dentin of etch-and-rinse and self-etching simplified adhesive systems. METHODS: 40 healthy molars were used. The crowns of teeth were removed at the dentinoenamel junction, and remaining roots were sectioned in the mesiodistal direction along th

23. Efficacy of 1.23% APF gel applications on incipient carious lesions: a double-blind randomized clinical trial
The aim of this double-blind randomized clinical trial was to evaluate the efficacy of 1.23% APF gel application on the arrest of active incipient carious lesions in children. Sixty 7- to 12-year-old children, with active incipient lesions were included in the study. Children were divided randomly into 2 groups: 1.23% APF gel and placebo gel applications. Ea

24. Efeito do ph e da concentração de flúor presente em dentifrícios líquidos no controle de cárie em área não fluoretada: estudo clpinico randomizado.
The aim of this randomized clinical trial was to evaluate the effect of pH and fluoride concentration in liquid dentifrices in the control of dental caries in early childhood, in non-fluoridated area. In addition, this study evaluated the influence of pH and fluoride concentration in toenails and in the fluoride uptake in plaque. The sample comprised 212 chi
