The efficacy of a test dentifrice containing nano-sized (several tens to hundreds of nm) calcium carbonate (hereafter NC) on enamel lesion remineralization was studied in an in vitro system that employed collagen-coated wells for cell culture, as a model of oral surfaces for NC retention. The well surfaces were treated with the test dentifrice and briefly rinsed with distilled water. Thin secti...

Introduced to the commercial market 40 years ago, fluoride dentifrice now accounts for nearly all dentifrice purchased in the United States. During this same time, the prevalence and severity of dental caries has declined while dental fluorosis prevalence has increased. While the caries decline can be largely attributed to widespread fluoride dentifrice use, as well as many other sources of flu...

UNLABELLED This study evaluated the effect of high fluoride dentifrice on the bond strength of brackets after erosive challenge. Eighty-four enamel specimens were divided into seven groups (n = 12): WN (distilled water/no acid challenge), W3C (distilled water/3 cycles of acid challenge), and W6C (distilled water/6 cycles of acid challenge) were not submitted to dentifrice treatment. Groups RF3C...

Fluoride dentifrice has been accepted widely for use in caries prevention and its effectiveness has been confirmed. In order to enable the use of fluoride dentifrice effectively in daily brushing, the present study was performed to examine the relationship between fluoride uptake and the amount of fluoride dentifrice used and brushing time for adults. We examined the relationship between fluori...

Objectives: The aim of this study is to investigate the effectiveness of dentifrice containing xylitol on the growth of salivary mutans streptococci. The amount of salivary mutans streptococci which was taken before and after tooth brushing from the groups using dentifrice containing xylitol and non-xylitol dentifrice are compared. The study was carried out to investigate the effect of dentifri...

Ingestion of fluoride dentifrice by preschool children recently has been implicated as a risk factor for dental fluorosis. The availability of dentifrices flavored for children could increase fluoride ingestion by young children at risk for dental fluorosis. This article reports results of a pilot study of use of regular-flavored dentifrice and those flavored for children among 29 preschool chi...

A vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as DNA, proteins and lipids. When free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. Therefore, the body should be protected by an enzymatic or no...

AIM The aim of this in vitro study was to evaluate the surface roughness and hardness of both unbleached and bleached (opalescence; 10% carbamide peroxide) human enamel brushed with water (without dentifrice), fluoride abrasive dentifrice (Colgate Total) and whitening dentifrice (Natural White). MATERIALS AND METHODS Human enamel samples were obtained from third molars and randomly divided in...

This study was conducted to assess the preventive effect of aqueous extract of Berberis integerrima Bge. root (AEBIR) on liver damage and oxidative stress induced by diabetes mellitus in rats. Forty male rats were divided into 5 groups as follows: 1- normal (N); 2- normal + barberry (N+B) (they received barberry root extract for 6 weeks); 3- diabetic (D) (they received Streptozotocin (STZ), 65 ...
