摘要

Oral biofilms are intricate microbial communities that can enhance oral health, yet their equilibrium is susceptible to disruption, leading to oral infectious diseases. The most prevalent of these are dental caries, periodontitis, and peri-implant infections. The formation of pathogenic biofilms is the primary cause of these diseases, and their resistance to antimicrobial agents and immune responses poses significant treatment challenges. Researchers have recently implemented microbiome-based strategies, including probiotics, prebiotics, synbiotics, and postbiotics, to modulate biofilm composition and restore microbial equilibrium. Probiotics exert their health effects by competitively inhibiting pathogenic bacteria, producing antimicrobial compounds, and interacting with the immune system. Moreover, prebiotics can selectively stimulate beneficial bacteria, while synbiotics and postbiotics increase these effects using synergistic mechanisms. Recent studies suggest that integrating these strategies into oral healthcare can offer effective, non-invasive approaches to manage biofilm-related oral infections. Notwithstanding the challenges, issues pertaining to strain-specific efficacy, probiotic viability, and long-term colonization remain to be addressed. This review has collated recent research in this area and highlights promising therapeutic directions for improving oral health outcomes.
