Abstract :
Probiotic is defined as “live microbial food ingredient that, when ingested in sufficient
quantities, exerts health benefits on the consumer” (International Life Science
Institute). Probiotic is derived from Greek language meaning “for life” and it was first
used by Lilly and Stillman in 1965 to describe “substances secreted by one
microorganism which stimulates the growth of another.” The original observation of
the positive role played by some selected bacteria was scientifically investigated by Eli
Metchnikoff who proposed that lactic acid-producing strain Lactobacillus bulgaricus
(contained in the Bulgarian yogurt) is able to displace pathological intestinal microbiota.
Probiotics’ role for treatment of general diseases like intestinal diseases, lactose
intolerance, diabetes, etc., has been documented in literature. During the past few
years, extensive research has been done to know the role of dietary as well as oral
probiotics for treatment of oral diseases. Present article documents health benefits of
probiotics for maintainence of oral health.
