In vitro fluoride uptake by bovine enamel from aesthetic restorative materials

Abstract

Enamel acquired significant amounts of fluoride from all materials with variations during the test intervals.

“…The compomers set by free radical polymerization only with limited acid-base reaction occurring later as the material absorbs water from the oral environment. Fluoride release from RMGICs is known to be similar to that of conventional GICs, whereas compomers produce a low and relatively constant fluoride release 1 . The pattern of fluoride release from both GIC and compomers is characterized by an initial rapid release followed by a rapid reduction in the amount of release after a short immersion period 6,8 .…”

“…The acid etch biopsy technique was used to determine the enamel fluoride uptake and calcium was determined via atomic absorption spectrophotometry 1 . The amount of fluoride in the samples was determined by direct potensiometric analyses with the use of a combination fluoride-ion selective electrode (Orion combination fluoride ionalyser 96-09-00, Orion research, Cambridge, USA).…”

“…Fluoride has been well-documented as an anticariogenic agent, and with the observation of inhibiting secondary caries formation, particular attention has been focused on the development of various fluoride-releasing restorative materials [1][2][3][4][5][6] . A variety of mechanisms are involved in the anticariogenic effects of fluoride, including the Sonuç: Giomerlerin gelişmiş fiziksel özellikleri ve cam iyonomerlere benzer uzun süreli fluorid salınımı göz önüne alındığında çocuk diş hekimliği için uygun bir materyal olduğu bulgulanmıştır.…”

“…Unlike GICs and RMGICs, both giomers and compomers require a resin bonding system after acid etching 4,[10][11][12][13][14] . A clear understanding of the mechanisms involved in the anticariogenic effects of fluoride and determining which materials have optimal fluoride release for caries resistance would ensure appropriate restorative material selection at the clinical setting 1,7,8 . With this aim, the relative concentrations and the duration of fluoride release in addition to fluoride uptake have been the interest of research.…”

“…Conventional glass ionomer cements (GIC) possess certain unique properties that make them useful as restorative and adhesive materials, including adhesion to tooth structure, anticariogenic properties due to release of fluoride, thermal compatibility with tooth enamel, and biocompatibility 1,2 . On the other hand, to overcome the problems such as moisture sensitivity and low initial mechanical strengths typical for GIC, resin modified glass ionomer (RMGIC) and polyacid-modified composite resin (compomer) were developed.…”
