“…All medications based on the tested brown propolis showed antimicrobial activity against E. faecalis, which is in agreement with previous studies 13,14,19,27 and with the fact that propolis exhibits significant antimicrobial activity against the more resistant, gram-positive facultative and strictly anaerobic species. 27 The 20% crude propolis extract associated with calcium hydroxide paste exhibited an antimicrobial activity similar to the 40% crude propolis extract associated with calcium hydroxide paste, but it performed better than the isolated calcium hydroxide.…”

“…27 The 20% crude propolis extract associated with calcium hydroxide paste exhibited an antimicrobial activity similar to the 40% crude propolis extract associated with calcium hydroxide paste, but it performed better than the isolated calcium hydroxide. Because there are no previous studies regarding the association between calcium hydroxide paste and crude propolis extracts at different concentrations, this result indicates the need for further investigation into the isolation and identification of brown propolis components.…”

The aim of this study was to evaluate the in vitro antimicrobial activity of Brazilian brown propolis as an intracanal medication against Enterococcus faecalis. Thirty dentin discs prepared from intact freshly extracted bovine maxillary central incisors were infected with E. faecalis for 21 days. The specimens were distributed into six groups according to the medicament used as follows: G1-calcium hydroxide paste; G2-Carbowax 400 (control group); G3-20% brown propolis paste; G4-40% brown propolis paste; G5-20% brown propolis paste + calcium hydroxide paste; and G6-40% brown propolis paste + calcium hydroxide paste. The experimental pastes were placed into the canal lumen and left for 14 days. After each period, irrigation was performed with sterile saline to remove the medicament, and the canals were dried with sterile paper points. The dentin chips were removed from the canals with sequential sterile round burs at low speed and were immediately collected in separate test tubes containing BHI broth. The tubes were incubated at 37°C, and microbial growth was analyzed by spectrophotometry after 15 days. All the experimental medications significantly reduced the number of viable bacteria. The G4 and G5 pastes were more effective than the G1 paste, with 35.8%, 41%, and 21.3% antibacterial activity, respectively. Brazilian brown propolis shows antibacterial capacity against E. faecalis.

“…Paper disks were used by Ikeno et al (10) to measure the anti-bacterial activity of Chinese and Japanese propolis, relating inhibition zones ranging from 6.0 to over 8.0 mm for S. sobrinus and of 5.5 to 6.8 mm for S. (17) used plate diffusion and 5 mm paper disks to evaluate the antimicrobial activity of extracts of Brazilian propolis, reported inhibition zones ranging from 0.5 to 1.5 mm beyond the edge of the disks. Koo et al (11) used agar diffusion with eight mm steel cylinders to measure the inhibition of oral bacteria by Brazilian propolis, reporting average inhibition zones of 2.00 -2.17 mm beyond the perimeter of the cylinder for S. mutans and of 2.25 mm for S. sobrinus. On the whole, one cannot conclude if the variation in results was due to the method employed or actually a result of the activity of the propolis samples tested.…”

Brazilian propolis from São Paulo state was submitted to extraction using several solvents, resulting in extracts with different composition. These extracts were submitted to Thin Layer Chromatography (TLC). Bioauthographic analysis of the TLC plates identified fractions with inhibitory activity, which were then analysed by High Performance Liquid Chromatography (HPLC). In vitro assays, commonly used to evaluate the activity of propolis against Gram-positive bacteria, were compared to determine which rendered the most consistent results. The bactericidal activity of these extracts were analysed by Serial Dilution in Tubes and Agar Plate Diffusion. Serial Dilution in Tubes obtained the most consistent results, with the Minimal Bactericidal Concentration of the extracts ranging between 2.5 and 20.0 mg/mL, for the species of Gram-positive bacteria tested. The results of the Agar Plate Diffusion were directly proportional to the hydro-solubility of the extracts and did not evaluate their bactericidal activity correctly. The bactericidal activity of this sample of propolis was due to the combined effect of several components that were identified by HPLC and were best extracted using 50% ethanol as a solvent.

“…Ceanothic acid and ceanothetric acid from the native American plant Ceanothus americanus has been shown to inhibit the growth of S. mutans, Actinomyces Viscosus, and Porphyromonas gingiValis (12). Propolis ethanolic extract exerts in vitro antibacterial action against a number of oral microorganisms and inhibits cell adhesion as well as water-insoluble glucan formation (13). Bakuchiol, a phenolic isoprenoid derived from the seeds and leaves of the tree Psoralea corylifolia L., native to China, showed a bactericidal effect against oral bacteria (14).…”

Wine contains a number of biologically active compounds with beneficial effects on human health. The antibacterial action of commercial red and white wines against oral streptococci responsible for caries development and against S. pyogenes responsible for pharyngitis was studied. Its postcontact effect against S. mutans was also studied. Both wines displayed activity. The compounds responsible for such activities were succinic, malic, lactic, tartaric, citric, and acetic acid. The synthetic mixtures of the organic acids tested at the concentrations found in wine had greater antibacterial activity than the beverages, indicating that in wine they are inhibited by other components. Wine polyphenols displayed no activity against oral streptococci or S. pyogenes. Findings show that wine is active against oral streptococci and S. pyogenes and suggest that it enhances oral health.
