Oral Microbiology in Periodontitis

A comprehensive overview of the oral microbiome and its significant role in both localized oral diseases and systemic health issues. The texts detail the microbial ecology of the mouth, emphasizing that dental plaque is a complex biofilm that progresses through stages of colonization, primarily causing periodontitis and dental caries. Crucially, the sources discuss the pathogenesis of periodontitis, highlighting specific Gram-negative anaerobic bacteria like Porphyromonas gingivalis and Treponema denticola, and exploring the resulting host immune response involving cytokines and Toll-like receptors. Furthermore, a key theme is the connection between oral microorganisms and autoimmune diseases through the mechanism of molecular mimicry, where microbial epitopes resemble host autoantigens. Finally, the texts cover the microbial challenges presented by denture biofilms, including the association with Candida albicans and the risk of systemic infections.
