ABSTRACT
Microbiologists play a crucial role in periodontal diagnosis by identifying, quantifying, and assessing the susceptibility of specific subgingival pathogens, such as the "Red Complex" bacteria (P. gingivalis, T. forsythia, T. denticola). They enable personalized treatment by analyzing samples for specific pathogens in cases of refractory, aggressive, or non-responsive periodontal disease. Core Functions in Periodontal Diagnosis are: 1) Sample Management: Proper collection, transport, and analysis of anaerobic, fastidious bacteria within the subgingival biofilm, 2) Pathogen Identification: Using techniques like culture, PCR, and DNA-DNA hybridization to detect periodontal pathogens in subgingival plaque samples, 3) Risk Assessment: Identifying patients with high-risk microbiota profiles before clinical sign such as pocket deepening, fully manifest, 4) Antibiotic Susceptibility Testing: Determining the most effective antimicrobial therapy, particularly for aggressive or refractory periodontitis and 5) Treatment Monitoring: Evaluating the efficacy of periodontal therapy (SRP - Scaling and Root Planing) by assessing the reduction or eradication of pathogens.
