Summary
A 2% propolis rinse showed effectiveness comparable to a positive control rinse in managing gingivitis over 21 days without oral hygiene. This study utilized a co-twin design to assess propolis for oral health.
Area of Science:
- Oral Health Research
- Periodontology
- Natural Product Therapeutics
Background:
- Gingivitis is a common oral inflammatory condition.
- Propolis, a natural resinous substance, has demonstrated antimicrobial and anti-inflammatory properties.
- Evaluating natural products for oral hygiene is crucial for developing effective preventative strategies.
Purpose of the Study:
- To assess the efficacy of a 2% typified propolis rinse in managing induced gingivitis.
- To compare the effectiveness of propolis rinse against a positive control rinse (sodium fluoride and cetylpyridinium chloride).
- To utilize a co-twin study design for a controlled clinical trial.
Main Methods:
- A randomized, double-blind, controlled clinical trial involving 21 twin pairs (42 participants).
- Gingivitis was induced over 21 days with participants rinsing twice daily with either 2% propolis or a positive control rinse.
- Gingivitis was quantified using the Papillary Bleeding Score (PBS) and digital gum imaging (G-parameter) at baseline and after the intervention period.
Main Results:
- The study included 38 participants aged 13-22 years, with balanced baseline gingivitis measures.
- No significant difference was observed in average Papillary Bleeding Score (PBS) between the propolis rinse and positive control groups.
- Similarly, the G-parameter measurements showed no significant difference between the two rinse groups after 21 days.
Conclusions:
- A 2% typified propolis rinse demonstrated equivalent efficacy to a positive control rinse in preventing gingivitis progression during a 21-day period of no oral hygiene.
- Propolis rinse can be considered a viable alternative for gingivitis management in conjunction with other oral care practices.
- The findings support the potential of propolis as a natural therapeutic agent in oral health.
