OBJECTIVE The time of contact between the product and enamel surface is important in ensuring the efficacy of fluoride varnishes. Thus, some alternatives could avoid fluoride loss to saliva and improve the anticariogenic action of the product. This study evaluated the effect of an experimental coat on the anticariogenic action of fluoride varnishes. MATERIAL AND METHODS Enamel bovine blocks w...

Chamaecyparis obtusa (C. obtusa) is known to have antimicrobial effects and has been used as a medicinal plant and in forest bathing. This study aimed to evaluate the anticariogenic activity of essential oil of C. obtusa on Streptococcus mutans, which is one of the most important bacterial causes of dental caries and dental biofilm formation. Essential oil from C. obtusa was extracted, and its ...

This study, for the first time, investigated the in vitro inhibitory effects of Potentilla recta extracts and subfractions obtained with solvents of different polarity (aqueous, 50% ethanol, diethyl ether, ethyl acetate and n-butanol) against cariogenic Streptococcus spp. strains. It was found that the tested samples inhibited the growth of oral streptococci. Furthermore, all five P. recta prep...

Streptococcus mutans, the primary etiologic agent of dental caries, possesses a series of virulence factors associated with its cariogenicity. Alternatives to traditional antimicrobial treatment, agents selectively inhibiting the virulence factors without necessarily suppressing the resident oral species, are promising. The anticariogenic properties of tea have been suggested in experimental an...

UNLABELLED Regular supply of fluoride ions to the oral environment is one of the prophylactic actions against dental caries. Fluorides, whose exogenous action combines with saliva properties, condition the anticariogenic effect. Fluoride ions exhibit high chemical activity, can alter the oral environment parameters and inhibit the activity of enzymes. PURPOSE In the current study, the effect ...
