The present study was aimed to determine the type of Propolis in vitro that has greater antimicrobial effect against Streptococcus mutans ATCC 25175. Prospective, longitudinal, comparative and experimental study was conducted in the laboratory of microbiology section of the medical school National University of Trujillo, and included three types of Propolis obtained from the coast side of the region of La Libertad, Chepen (type A), in the Region of San Martin, Moyobamba (type B), and the Region of Ayacucho (type C). Ethanol extract of Propolis 10% was prepared, which were soaked in filter paper disks Whatman No. 3 previously sterilized, whereafter the discs were applied in the culture medium Mueller Hinton-blood inoculated previously with Streptococcus mutan ATCC 25175, it was incubated for 24 and 48 hours, and the extent of the zone of inhibition was taken. Additionally, the bactericidal effect of the concentration was determined by the dilution method in tubes abbreviated. Through statistical Kruskall-Walli was shown that there is a difference in activity between 24 and 48 hours, which is explained by the MannWhitney where he scored that after 24 hours type Própolis A and C not differ from each other but differ from B, obtaining the first two best results. At 48 hours the three types of propolis are differentiated, obtaining with the C type the best performer followed by a and B, this as for measuring the halos of inhibition while the CFU count no significant differences in activity were obtained.
