Relationship between the fluoride concentration of the fluoride-releasing elastomers and the acquired acid resistance of human enamel in vitro.
The objective of the study was to evaluate the relationship between the fluoride concentration of the fluoride-releasing elastomers and the acquired acid resistance of human enamel. Four kinds of fluoride concentration of the experimental fluoride-releasing elastomers were 1.25, 2.5, 3.75 and 5.0 wt%. An enamel block was cut into two smaller enamel blocks, one of which was set with an elastomer...
متن کاملThe fluoride concentration in the enamel of permanent central incisors.
THE caries inhibitory effect of fluoride is well documented (Brudevold et a], 1967; Horowitz and Heifetz, 1970). •As the initial site of the caries lesion Occurs on the surface of the tooth at the plaque/tooth interface, the fluoride con centration in the surface layers of enamel is important in combating the carious process (Isaac et al, 1958; Naylor, 1969). The fluoride in the enamel is deri...
متن کاملFluoride varnish concentration gradient and its effect on enamel demineralization.
PURPOSE Two of the 4 fluoride varnishes available on the American market today are sold in 10-mL tubes of 5% NaF varnish (Duraphat and Duraflor). Pilot studies have shown that a separation of contents within these tubes exists. The purpose of the current study was 4-fold: (1) to measure the fluoride concentration gradient in 10-mL tubes of fluoride varnish, based on resting position of the tube...
متن کاملPrevention of enamel demineralization with a novel fluoride strip: enamel surface composition and depth profile
There is no topically applicable low concentration fluoride delivery device available for caries prevention. This study was aimed to assess the use of a low concentration (1450 ppm) fluoride strip as an effective fluoride delivery system against enamel demineralization. The enamel surface composition and calcium-deficient hydroxyapatite or toothpaste treatments were investigated using X-ray pho...
متن کاملEffect of fluoride containing bleaching agents on enamel surface properties.
OBJECTIVES To evaluate the effects of fluoridated bleaching agents and post-bleaching fluoridation treatment on the whitening efficiency and microhardness of bovine enamel. METHODS Twenty five freshly extracted bovine incisors were cut into halves, embedded and then divided into the following five groups: Group 1, untreated controls; Group 2, treatment with 10% carbamide peroxide (CP) bleachi...
