Insights Into the Role of Streptococcus mutans and Candida albicans in Dental Biofilm Formation and Cariogenicity: A Literature Review.

Dental caries is a widespread chronic disease that affects a large proportion of both adults and children globally. is widely recognized as the primary pathogen responsible for dental caries, while frequently coexists with it, often forming a synergistic relationship. Despite this, the specific virulence mechanisms of these microorganisms, both individually and in coaggregation, as well as their collective impact on cariogenic potential, remain incompletely understood. This comprehensive review aims to examine both original and review articles addressing the virulence characteristics of these species, both independently and in coaggregation, and to assess how these interactions contribute to tooth demineralization, polysaccharide production, and the expression of virulence genes. The research reviewed here provides valuable insights into the physiological interactions between the two species, showing that these interactions lead to increased acid production within their coexisting biofilm, which enhances the cariogenic potential. These insights could guide future studies aimed at developing targeted strategies for preventing or mitigating dental caries.
