introduction: to compare the effects of 0.05% sodium fluoride (naf) mouthrinse, gc tooth mousse and gc mi paste plus on white spot formation inhibition. materials and methods: thirty pairs of extracted human premolars were cut in half mesio-distally with a disc. the teeth were coated with nail varnish, except a part of the buccal and/or lingual enamel, which was used as the test area, and then ...

There is a generally accepted hypothesis, warmly supported by the French authors, that demineralization is a common feature in tuberculosis. Much attention has been given to this subject by clinicians as well as biochemists. Attempts have been made to ' remineralize' the patient in order to make good the loss. Sergent, who reviews the early French work, was quite convinced of the value of calci...

The purpose of this study was to investigate the enamel remineralization potential of two toothpastes, one of which was based on Recaldent (CPP- ACP) and the other on NovaMin (Calcium-sodium-phosphosilicate). Human permanent molar teeth were subjected to three consecutive demineralization cycles. These cycles were followed by remineralization of the experimental groups by toothpastes containing...

The process of dental caries is determined by a delicate balance between pathological factors (bacteria and carbohydrates) that lead do demineralization and protective factors (saliva, calcium, phosphate and fluoride) that lead to remineralization. Contemporary approach to the treatment of dental caries includes preventive and prophylactic measures based on the notion of “demineralization and r...

We investigated single application of pastes containing a surface reaction-type pre-reacted glass-ionomer (S-PRG) filler on enamel demineralization. Human enamel blocks were polished using pastes containing S-PRG filler (0, 5, and 30%) and immersed in demineralizing solution for 5 days with daily change of solutions. The pH measurement and nanoindentation testing was carried out during the imme...

objective: the use of sugar-free chewing gums has been reported to be highly effective in the prevention of dental caries. this study carried out to compare the effect of mastic gum and a xylitol chewing gum on remineralization of caries-like lesions. materials and methods: in this cross-over, single blinded, in situ study, first, artificial caries-like lesions were created in six extracted hum...

citric acid and tetracycline hcl are the most common clinical root demineralization agents used in periodontal practice. in this comparative in vitro study the effects of nd: yag laser radiation on root surface was compared to that of citric acid and tetracycline hcl using sem. a total of twenty-one freshly extracted periodontally diseased single rooted premolar teeth were root planned in vitro...

The article presents the results of investigation phenomenon concentration polarization.
 technological parameters electrodialysis and electrodeionization processes at various applied voltages are presented. about influence polarization on efficiency electromembrane demineralization process sugar syrup were concluded.

Previous studies have shown that near-infrared (NIR) reflectance and transillumination imaging can be used to acquire high contrast images of early caries lesions and composite restorative materials. The aim of the study was to determine the optimum NIR wavelengths for imaging demineralized areas under dental sealants. Fifteen natural human premolars and molars with occlusal lesions were used i...

Alkali and alkali earth metals (AAEM) can be removed from lignocellulosic biomass via a new demineralization process constituting hydrothermal treatment. The dissolution mechanism of AAEM in different processes has not been extensively studied. This study employed calcium as representative the group, changes concentration ions during eucalyptus wood were kinetics modelled using Fick’s second la...
