📌 POINTS TO PONDER 

📣 PERIODONTAL HEALTH 

🔹Beneficial species of the host affect the disease progression by preventing the colonization/proliferation of pathogenic microorganisms, e.g. hydrogen peroxide produced by S.sanguinis is lethal to A. actinomycetemcomitans. 

🔹Sometimes, these species also degrade the virulence factors produced by the pathogens. 

⭐ Following are the beneficial microorganisms: 

🔺 S. sanguinis 

🔺 S. mitis 

🔺 Capnocytophaga spp. 

🔺 Veillonella 

🔺 Atopobium sp. 

🔺 Gemella sp.
