Periodontal diseases, characterized by chronic inflammation and progressive destruction of supporting tooth structures, are closely linked to the red complex bacteria—Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia. These pathogens significantly contribute to disease development, making their accurate detection essential for effective diagnosis and treatment. Traditional diagnostic methods, though widely used, often lack sensitivity and reliability, highlighting the need for molecular diagnostics to improve clinical outcomes. The advent of polymerase chain reaction (PCR) has transformed periodontal pathogen detection, offering exceptional sensitivity, specificity, and rapid identification. Advanced PCR variants enable precise bacterial quantification, species differentiation, and comprehensive microbial profiling, significantly enhancing diagnostic accuracy. The integration of PCR into routine periodontal diagnostics allows for early intervention, personalized treatment strategies, and improved disease monitoring. Future advancements, such as point-of-care PCR systems, next-generation sequencing, and artificial intelligence-driven analysis, hold the potential to further refine molecular diagnostics, paving the way for more efficient and targeted periodontal disease management.
