The commensal Porphyromonas species. Dominant in healthy mouths, where it makes up 40-60% of the total Porphyromonas reading. Standard saliva sequencing typically cannot reliably distinguish P. pasteri from P. gingivalis at the species level, so genus-level interpretation is often more honest. Health-associated.
No specific intervention needed. P. pasteri is part of the normal healthy oral community — preserving its niche means the standard healthy-mouth interventions (regular brushing, flossing, avoiding daily antiseptic mouthwash, not smoking) rather than anything P. pasteri-specific.
Daily antiseptic mouthwashes (chlorhexidine, CPC) and smoking, which deplete the broader healthy gram-negative anaerobic community including P. pasteri.
