SYNERGISTIC INTERACTIONS BETWEEN STREPTOCOCCUS MUTANS AND CANDIDA ALBICANS IN ORAL BIOFILMS AND ITS THERAPEUTIC IMPLICATIONS IN DENTAL CARIES: A NARRATIVE REVIEW

Background: Dental caries is a chronic, multifactorial disease resulting from microbial dysbiosis within the oral
biofilm. The persistent colonization and cooperative behavior of specific microbial species contribute significantly
to its pathogene.
Objective: This review explores the synergistic interactions between Streptococcus mutans and Candida albicans,
two prominent oral microorganisms, with a focus on their molecular crosstalk, clinical relevance, and implications
for targeted therapy.
Materials and Methods: A narrative synthesis was conducted based on peer-reviewed literature examining the
co- pathogenic mechanisms, biofilm dynamics, and emerging anti-biofilm strategies targeting dual-species
communities.
Results: Current evidence demonstrates that C. albicans enhances extracellular polysaccharide production by S.
mutans through glucosyltransferase activity, promotes glucan-mediated co-adhesion, and modulates virulence gene
expression in both organisms. Their co-existence leads to increased biofilm biomass, acidogenic potential, and
resilience against conventional antimicrobial measures. These interactions are notably prevalent in early childhood
caries and immunocompromised hosts.
Conclusion: The cross-kingdom synergism between S. mutans and C. albicans constitutes a potent pathogenic axis
in cariogenesis. Targeted disruption of this alliance through novel therapeutic strategies—such as
glucosyltransferase inhibitors, nanoparticle-based antimicrobials, and biofilm-disrupting agents—holds potential
for improving caries management, particularly in high-risk populations. Further clinical validation is necessary to
translate these findings into effective, personalized interventions.
