Abstract
Purpose. To evaluate the effect of Bee Propolis on salivary
Streptococcus mutans count and dental caries in rats.
Materials and Methods. Thirty six albino rats weaned at
age of 19 days free from indigenous pathogens were infected
by Streptococcus mutans. At the age of 25 days, rats were
randomly divided into: 1-received laboratory standard rat
ration blended with 10% propolis and 25% cariogenic diet
(Molasis), 2-received laboratory standard rat ration blended
with 10% propolis,3-received laboratory standard rat ration.
RESULT. After the expiremental period the result show that
propolis extracts did not show major effects on the viability
of mutans streptococci count. However reduce the incidence
and severity of dental caries even in present of cariogenic
diet. Conclution. Effect of propolis on streptococcus
mutans count and dental caries was significant even in the
presence of high cariogenic challenges.
