In situ effect of a dentifrice with low fluoride concentration and low pH on enamel remineralization and fluoride uptake.
Since the anticaries effect of a dentifrice with low fluoride concentration and low pH is unknown, the aim of the present study was to evaluate in situ the enamel remineralizing ability of this type of formulation. A double-blind crossover design employing 3 phases of 45 days was conducted. Six adult volunteers wore palatal devices containing 6 previously demineralized human dental enamel slabs...
متن کاملpH-cycling models to evaluate the effect of low fluoride dentifrice on enamel de- and remineralization.
Since the currently available pH-cycling models do not differentiate the anti-caries potential of dentifrices with low fluoride (F) concentration, two models were developed and tested in the present. Bovine enamel blocks were subjected to the models and treated with F solutions containing from 70 to 280 microg F/mL in order to validate them in terms of dose-response effect. The models were also...
متن کاملEffects of fluoride dentifrice on remineralization of demineralized primary enamel.
This study was performed to compare the remineralizing effects of various concentrations of fluoride containing dentifrices against artificial demineralization of primary enamel. One hundred twenty primary incisors were partly covered with a nail varnish, leaving a 1 x 1 mm window, then placed in demineralizing solution for 96 hours to produce artificial carious lesions 60-100 microm in depth. ...
متن کامل[Dose-response effect of a dentifrice formulation with low fluoride concentration - an in vitro study].
The utilization of dentifrices with low fluorine concentration, for children under 6 years of age, has been suggested to reduce the risks of dental fluorosis. However, in order to have anticariogenic potential, the dentifrice should form loosely-bound fluorine (CaF2) on dental enamel. Considering that the formation of CaF2 is a function inversely related to pH, dentifrices with pH 5.5, with 275...
متن کاملEffect of low fluoride acidic dentifrices on dental remineralization.
This study evaluated the capacity of fluoride acidic dentifrices (pH 4.5) to promote enamel remineralization using a pH cycling model, comparing them with a standard dentifrice (1,100 µgF/g). Enamel blocks had their surface polished and surface hardness determined (SH). Next, they were submitted to subsurface enamel demineralization and to post-demineralization surface hardness analysis. The bl...
