Aim: To evaluate the salivary biomarkers and plaque index after a treatment with a propolis-contained toothpaste. Materials and Methods: This is a longitudinal, randomized, double-blind study where 76 participants were randomized into two groups: Group I: Fluoridated Red Propolis toothpaste; Group II: Fluoridated toothpaste. The participants were selected in a municipality without fluoridated public water. All participants received standardized oral hygiene instructions from the same instructor for 3 daily brushings (after breakfast, after lunch, and before bed) for a period of 2 min; Saliva samples were collected before (D0) and after 28 days (D28) of treatment for analysis of pH and total protein, amylase, and IL-10. Saliva was collected in the initial consultation and on return, totaling two collections. All samples were collected under the same conditions, by the same operator and between 9:00 am and 11:00 am in order to minimize the influence of circadian rhythm on salivary flow. Results: On D0 and D28, the various treatments had no effect on total salivary proteins (G1: P = 0.0746; G2: P = 0.2144), and the pH stayed about the same. Additionally, there was no change in the amylase activity in G1 (P = 0.1877) or G2 (P = 0.4674). Significant decreases in G1 (P < 0.0001) and G2 (P = 0.03) were observed with IL-10. There was no statistically significant difference in the salivary flow between the BRP toothpaste-treated group (P = 0.172) and the commercial fluoridated toothpaste-treated group (P = 0.329). Compared to G2 (P = 0.03), G1 showed a superior decline in the plaque index (P = <0.0001). Conclusions: After 28 days of using the toothpastes, there were no changes in the amylase, pH, or total protein indicators. After 28 days, there was a decrease in the propolis group’s IL-10 dose and plaque index. [ABSTRACT FROM AUTHOR]

Background: This study evaluated the antimicrobial activity of brazilian red propolis (BRP) dentifrice and compare in vitro. Materials and methods: Strains of S. mutans ATCC UA159 were used in the present study. This study compared the antibacterial effects of BRP extract, BRP containingdentifrice and one antimicrobial commercial dentifrice (Parodontax) against S. mutans. For the evaluation of the antimicrobial activity the microdilution method was used in culture broth. The strain was activated by incubation at 37°C overnight in Brain Heart Infusion (BHI) culture medium, in an anaerobic jar. To the wells of the microplates were added 100μL of BHI broth, 20μL of the substances tested (experimental groups), at concentrations ranging from 100 μL/mL to 0.0488 μL/mL, and 80 μL/mL of the standardized microbial suspension. The microplates were incubated for 24 hr in a bacteriological oven at 37°C. Visual inspection of the colour changes and reading in BioTek microplate reader at 570nm was performed to determine the Minimum Bactericidal Concentration (MBC). Mean values and standard deviations were calculated. ANOVA followed by Dunnett's test was performed; p-value of less than 0.05 was considered significant. Results: BRP extract and BRP containing-dentifrice showed antimicrobial activity against S. mutans up to the concentration of 0.3906 μg/mL. The BRP extract and dentifrice showed bactericidal effect at a concentration of 1.5625, but was able to reduce microbial viability at a concentration of up to 0.3906. Parodontax dentifrice showed antimicrobial activity at all dilutions (p< 0.05), presenting a bactericidal effect in the same concentration of the extract (1.5625). It was concluded that all the groups observed had antimicrobial activity against S. mutans. There was no difference between the propolis extract and the common dentifrice. Conclusion: BRP in pure form and processed in a toothpaste shows some antimicrobial activity against S. mutans but less than a commercial toothpaste containing herbal extracts and sodium bicarbonate.

Objective: The objective of this study was to evaluate the perceptions of patients undergoing orthodontic treatment, for the perceptions and possible adverse effects after using toothpaste based on Brazilian Red Propolis (BRP). Materials and Methods: This is a longitudinal clinical study. 40 participants used a toothpaste BRP three times a day for a total of four weeks. After 4 weeks, the end of the study, participants completed a questionnaire with a scale ranging from 0 to 10 for parameters such as taste, nausea, cleanliness, ease, irritation, odor and sense of taste change. Results: The taste, cleaning ability, ease and odor had high scores. There were no reports as to the possible adverse events such as irritation and change in taste. One participant reported the occurrence of nausea after brushing, indicating score 1. Conclusion: The use for 4 weeks of the BRP toothpaste did not cause adverse effects and had a good acceptance by the users. [ABSTRACT FROM AUTHOR]
