[Streptococcus mutans and dental caries: microbiological aspects].

Abstract

The central role of Streptococcus mutans in the pathogenesis of caries is universally recognized. In this article we discuss bacterial metabolism relevant to plaque formation and enamel destruction, and review current methods and new prospects in caries prophylaxis: the use of fluorine, possible substitutes for sucrose, active and passive immunoprophylaxis, teeth colonization with non-cariogenic strains of S. mutans. No one of these methods can be considered a definitive solution for every caries problem, but short term major achievements can be reasonably attained by ongoing field research.
