Microbiological ETIOLOGY IN PERIODONTAL DIAGNOSIS: Unraveling the Basis and Future Diagnostics of Periodontitis

This book explores the microbiological etiology, pathogenesis, and advanced diagnostics of periodontal disease. It traces the evolution from early plaque theories to the modern polymicrobial synergy and dysbiosis model. A key focus is on how keystone pathogens, especially the red complex (P. gingivalis, T. forsythia, and T. denticola), disrupt the healthy oral microbiome and trigger chronic inflammation.Crucially, periodontal tissue and bone destruction are largely driven by the host's exaggerated immune-inflammatory response, which is heavily influenced by oxidative stress. The text also highlights the bidirectional impact of periodontitis on systemic conditions like diabetes, cardiovascular disease, and adverse pregnancy outcomes.Finally, the document reviews the transformative role of modern diagnostics. It highlights the shift to molecular methods, the use of salivary biomarkers, and the integration of Artificial Intelligence to enhance early detection, radiographic analysis, and personalized treatment planning.
