Effects of Brazilian green propolis glycolic solutions against bacterial biofilm on elastomers used in maxillofacial prostheses

Maxillofacial prostheses are among the modalities of prosthetic rehabilitation but disinfectant solutions for their cleaning have been barely explored. The purpose present study was to evaluate antibacterial effects a Brazilian green propolis glycolic (PGL) solution on removal biofilm from surface two maxillofacial elastomers (room temperature vulcanization [RTV] and high consistency silicone rubber [HCR]). A total 42 specimens (3×10 mm) were made with these Staphylococcus aureus allowed grow 24 hours biomaterials. Specimens (n=3) randomly allocated following treatment groups by immersion 15 minutes: 0.9% saline solution; 2% chlorhexidine gluconate (CHX); 11%, 16% 20% PGL; Daro Brand® antimicrobial liquid agent gel soap. Quantitative assessment performed counting number colony-forming units (CFU). Two-way ANOVA employed data analysis. both treated PGL at concentrations 20%, as well CHX, did not reveal CFU/mL S. strain, indicating broad spectrum antibiofilm action solutions. In addition, showed lower in compared soap solution. Therefore, disinfection is effective might be considered promising alternative eliminating minutes.
