Progressive stages of subsurface demineralization of human tooth enamel
Archives of Oral Biology, 1977Abstract Samples of intact human dental enamel were exposed to a lactate buffer known to produce subsurface demineralization. After exposure times of 0, 18, 36 and 72 h, the water vapour sorption isotherms were determined and the corresponding pore-volume distributions and specific surface areas calculated. Three distinct demineralization stages were

Fluoride Remineralization of Demineralized Bovine Tooth Enamel and Hydroxyapatite Pellets
Journal of Pharmaceutical Sciences, 1981Both bovine enamel and hydroxyapatite pellets were remineralized in a fluoride-containing remineralization solution after prior demineralization for various lengths of time. In both the enamel and pellet systems, the degree of remineralization attainable was directly related to the extent of prior demineralization, although the demineralized material ...

Comparative evaluation of combined remineralization agents on demineralized tooth surface
Nigerian Journal of Clinical Practice, 2019The aim of this in vitro study was to evaluate the effects of casein phosphopeptides (CPP)-ACPF, NovaMin+ fluoride-containing toothpaste and Xylitol+ fluoride containing cream on demineralized areas on the enamel surface.A total of 100 enamel slab samples was prepared to investigate in the laboratory experiments. For this purpose, a total of 50 freshly

In vitro demineralization of tooth enamel subjected to two whitening regimens
The Journal of the American Dental Association, 2013The resistance of bleached enamel to demineralization has not been elucidated fully. In this study, the authors aimed to examine the level of in vitro demineralization of human tooth enamel after bleaching by using two common bleaching regimens: home bleaching (HB) and office bleaching (OB) with photoirradiation.The authors bleached teeth to equivalent

Effect of Tooth–Bound Fluoride on Enamel Demineralization/ Remineralization in vitro
Caries Research, 2000The effect of tooth–bound fluoride (F) on enamel caries formation was investigated under the condition that loosely bound F was essentially absent. Eighteen thin enamel sections, prepared from the lingual or buccal surfaces of extracted human molars, were embedded in acrylic resin with the enamel surfaces exposed.

Assessment of inorganic and organic components in demineralized tooth graft material
AIP Conference Proceedings, 2020The purpose of the study was to evaluate the surface substructure, inorganic and organic components present in partially demineralized tooth bone graft material in young and old, male and female subjects, which may vary due to formation of secondary dentin suggesting decrease in calcium content as we age.

Prevention of Sucrose-induced Demineralization of Tooth Enamel by Chewing Sorbitol Gum
Journal of Dental Research, 1989Measurements were made of the effect of chewing sorbitol gum on the intra-oral demineralization induced by rinsing with 10% sucrose solutions. Blocks of bovine enamel were covered with a layer of Streptococcus mutans IB1600, and mounted on palatal appliances that were worn by five subjects for defined periods of time.

Demineralization inhibition of direct tooth-colored restorative materials.
Operative dentistry, 2004This study compared the demineralization inhibition properties of fluoride releasing tooth-colored restorative materials. Materials evaluated included a giomer (Reactmer, Shofu [RM]), a conventional glass ionomer (Fuji II, GC [FJ]), a resin modified glass ionomer (Fuji II LC, GC [FL]) and a compomer (Dyract AP, Dentsply [DY]).
