ABSTRACT
Objectives: The aim of this study was to compare the effects of four different mouthrinse
containing propolis solutions and mouthrinse containing 0.2% chlorhexidine (CHX) on
oral microorganisms and human gingival fibroblasts.
Methods: Four different solutions of propolis were prepared and propylene glycol and
alcohol were used as solvents for each propolis sample. Mouthrinse containing propolis
was prepared at four different concentrations as 10%, 5%, 2.5% and 1%. Besides, CHX
was used as control group. The antibacterial effects of five solutions on oral microorganisms
were tested and their cytotoxic effects on human gingival fibroblasts were evaluated
by agar diffusion test.
Results: At this concentrations effectiveness of mouthrinse containing propolis samples
on oral microorganisms were not found as effective as CHX. On the contrary, samples
found less cytotoxic on human gingival fibroblasts than CHX.
Conclusions: Standardized preparations of propolis can be used as a mouthrinse at
appropriate concentrations. To obtain a standardized chemical composition, advanced
researches are needed. (Eur J Dent 2007;1:195-201)
