Inhibitory Efficacy of 3 Types of Probiotics on the Growth of Bacteria.

Background: Amongst the specific plaque pathogen (Aa) ATCC 43718 serotype b is one of the highly virulent bacteria that causes periodontitis. Probiotic therapy is a treatment in which the lactic acid bacteria in are utilized to impede the colonization and growth of the pathogenic bacteria to prevent the further formation of dental plaque.

Objective: The present research aimed to evaluate inhibiting effect of purified bacteria from various commercially available yogurt product containing bacteria named ( strain Shirota; and ; Prodentis) on the growth of Aa.
