BACKGROUND This study aimed to investigate the effects of a fluoride varnish with added Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP) treatments on acid resistance of primary teeth enamel. METHODS Enamel specimens obtained from 40 primary incisors (for surface microhardness testing) and 40 primary molars (for demineralization depth measurement) were randomly divided into four gr...

BACKGROUND Some fluoridated toothpastes, available commercially, are described to have a protective effect against dental erosion. OBJECTIVES To evaluate the influence of the selected marketed toothpastes on the human enamel exposed to acid beverages. MATERIAL AND METHODS Enamel specimens from extracted human teeth were prepared (n = 40). Specimens were randomly divided into 10 experimental...

AIM To evaluate the effects of postbleaching antioxidant application fluoridation treatment on the surface morphology and microhardness of human enamel. MATERIALS AND METHODS Ten freshly extracted human maxillary central incisors were cut at cementoenamel junction. Crown portion was sectioned into six slabs which were divided into five groups: group A - untreated controls; group B - 35% carba...

OBJECTIVE The feasibility of a fluoride positron emission tomography/computed tomography (PET/CT) scan for imaging atherosclerosis has not been well documented. The purpose of this study was to assess fluoride uptake of vascular calcification in various major arteries, including coronary arteries. METHODS We retrospectively reviewed the imaging data and cardiovascular history of 61 patients w...

We describe a method for determining fluoride with ion-selective electrodes (ISEs). Tartrate and Tris-based total ionic strength adjustment buffers (TISABs) were found to lower the interference from aluminum to a greater extent than conventional citrate-based TISABs. We adopted a solid TISAB addition method that is simple to perform, and can be carried out without lowering the level of fluoride...

objectives: this study aimed to assess the effect of applying casein phosphopeptide–amorphous calcium phosphate (cpp-acp) paste, casein phosphopeptide–amorphous calcium phosphate fluoride (cpp-acpf) paste and sodium fluoride gel on surface microhardness of enamel after microabrasion. materials and methods: thirty freshly extracted human premolars were selected. all samples were subjected to har...

Blocks of human enamel were cycled through a demineralization--F-treatment-remineralization procedure and then analyzed for fluoride and the presence of caries-like lesions. Treatments with a sodium fluoride gel (5000 ppm F) increased the enamel fluoride concentration to 6500 ppm F, whereas a stannous fluoride gel (1000 ppm F) increased enamel fluoride to about 1200 ppm F. Although a control tr...

Consumption of acidic foods and drinks and other factors that cause enamel wear are responsible for the daily enamel loss and degradation. Use of some toothpastes that have been showed to possess different properties of remineralisation and/or repair of the enamel surface may help to protect tooth enamel. The aim of this study was to evaluate whether the use of toothpaste containing Zn-carbonat...

Fourteen cattle on a Kansas pasture died from ingestion of a wood preservative compound containing sodium fluoride and copper naphthenate. Clinical signs included depression, anorexia, ataxia, diarrhea, and recumbency. Grossly visible lesions included perirenal edema, pale kidneys, and forestomach ulceration. All 3 cows that had postmortem evaluations had extensive renal cortical tubular necros...
