[Preventive treatment of high caries-risk patients]

In most patients dental caries can be prevented by the frequent application of low concentrations of fluoride (toothpaste), in addition to restricted intake of sucrose, especially of between-meals snacks. In this paper the antimicrobial treatment against S. mutans with chlorhexidine gel and with chlorhexidine varnish is outlined. In patients treated with overdentures and in periodontally treated patients these antimicrobial treatments resulted in a strong caries reduction.
