Clinical and Microbiological Evaluation of Brazilian Red Propolis Containing-Dentifrice in Orthodontic Patients: A Randomized Clinical Trial.

Aim: To evaluate the efficacy of dentifrice containing brazilian red propolis (BRP) in adolescents under orthodontic treatment. . This is a randomized, double-blind, clinical trial. A total of 92 participants free from caries were randomized into 2 groups; the first received fluoride dentifrice, and the second received fluoride dentifrice incorporated with BRP. The gingival bleeding index (GBI) was recorded, and saliva was collected on the baseline (D0) and after 28 days (D28) for microbiological analysis. Data from GBI and Colony Forming Units (CFU) (log) were expressed as mean and standard deviation.

Results: The two groups reduced GBI significantly, with no difference in the intergroup analysis. In the intragroup analysis, it was observed that G2 ( < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance ( < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance ( bacteria, it was observed that only G2 had a statistically significant reduction ( < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance ( < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance (.

Conclusions: Dentifrice containing BRP demonstrated better clinical and microbiological activity. Future studies are needed to better identify effects to establish the use of dentifrice containing propolis in biofilm control.
