25,32) In experiments designed to evaluate the anticaries effect of low-fluoride toothpastes under different cariogenic conditions, it was demonstrated that, for caries-active children (33) or for those subject to a high cariogenic challenge
(biofilm accumulation and exposure to sugar 6-8 times/day), (28) low-fluoride toothpaste is significantly less effective than conventional fluoride toothpaste (1100 ppm F) in controlling caries progression.
A mathematical model of the influence of salivary urea on the pH of fasted dental plaque and on the changes occurring during a cariogenic challenge
Low molecular carbohydrates in the diet (white flour and sugar) are known to be metabolized by oral bacteria and provide a cariogenic challenge
to tooth surfaces.
Thus, a concentration of 1100 [micro]g F/g might not be high enough to reduce dentine demineralization if this dental tissue is exposed to a high cariogenic challenge
by biofilm accumulation and sugar exposure over time.
A dose-dependent effect has been demonstrated in the analysis of enamel resistance to a cariogenic challenge
following the application of an acidulated phosphate fluoride (APF) or sodium fluoride (NaF) gel, with greater fluoride absorption and a more efficient reduction in demineralisation in enamel treated with APF than with NaF [Delbem and Cury, 2002].
The number of affected teeth typically increases as the cariogenic challenge
At eight times each day (at 8:00, 9:00, 10:00, 11:00, 14:00, 15:30, 17:00, and 19:00 h), the slabs were extraorally treated with a 20% sucrose solution as a cariogenic challenge
The aims of this study were firstly to investigate the resistance to degradation of RMGIC and adhesive/CR restorations in sound and caries-affected primary dentine, submitted to load cycling and cariogenic challenge
in vitro, by evaluating nanoleakage.
11] The bacteria are supplied with an abundant energy supply to produce acid, which prolongs the cariogenic challenge
At the end of the cariogenic challenge
, the biofilm adhering to the surface was carefully removed, and the specimens were washed with deionized water.
Few in vitro studies have evaluated the real influence of cariogenic challenge
that simulates oral environment in shear bond strength tests.
