ACT This consensus statement supports implementation of caries management by risk assessment in clinical practice by using the following principles: modification of the oral flora, patient education, remineralization, and minimal operative intervention. The statement includes a list of supporters.

background: surface microhardness is a physical property which access the effect of chemical and physical agents on hard tissues of teeth, and a useful way to examine the resistance of fluoride treated enamel against caries. the purpose of this study was to evaluate microhardness of enamel following ph-cycling through demineralization and remineralization using suspensions of dentifrices with d...

It may be easier to gain patients’ compliance with the advice of administering a remineralizing agent immediately following an acidic challenge to enhance rapid remineralization of the softened tooth surface as well as serve as a mouth refresher, or alternatively, a neutralizing solution to buffer the acidic oral environment. Effective counseling on erosion preventive regimes should involve all...

The influence of ocean circulation changes on atmospheric CO2 hinges primarily on the ability to alter the ocean interior's respired nutrient inventory. Here we investigate the Atlantic overturning circulation at the Last Glacial Maximum and its impact on respired carbon storage using radiocarbon and stable carbon isotope data from the Brazil and Iberian Margins. The data demonstrate the existe...

[1] Th deficit and excess were examined in the upper 500 m of the Southern Ocean from Sub-Antarctic to Seasonal Ice Zones (Australian sector) during austral spring 2001. Th fluxes at 100 m indicate that particle export was low in the North (46.9–51.0 S), minimal in the Polar and Inter-Polar Frontal Zones and high in the South ( 61 S). These results are in tight agreement with new production est...

A new method for altered enamel surface remineralization has been proposed . To this aim carbonate-hydroxyapatite nanocrystals which mimic for composition, structure, nanodimensions, and morphology dentine apatite crystals and resemble closely natural apatite chemical-physical properties have been used The results underline the differences induced by the use of fluoride ions and hydroxyapatite ...

The objective of this in vitro study was to evaluate a possible remineralization of human carious dentin by calcium hydroxide. Thirty-nine freshly extracted human permanent and deciduous carious teeth were split into two halves. One half was used as control and the other as experimental. In the latter, a cavity was prepared and the remaining bottom layer of demineralized dentin capped with chem...

BACKGROUND During the past few decades, scientific developments in cariology, dental materials and diagnostic systems have changed dentistry's approach to diagnosis and management of dental caries. The authors summarize these developments. OVERVIEW Dental adhesives and restorative materials, new understanding of the caries process and remineralization, and changes in caries prevlance have cat...

The aims of this study were to investigate the effects of hesperidin, a citrus flavonoid, on human root dentin demineralization and collagen preservation, and compare it with chlorhexidine and grape seed extract. Specimens were assigned to different treatment groups: hesperidin, chlorhexidine and grape seed extract. Specimens were subjected to pH cycling by demineralization for 14 h, incubation...
