Abstract
Myrrha and Sage extract solutions are promising prophylactic and disinfectant agents against microorganisms, suggesting that these solutions might be useful as antimicrobial topical solutions for dental contamination. Three different concentrations of Myrrha and Sage extract solutions 2%, 5% and 10% were separately exposed to the Staph. aureus and chlorohexidine solution that is used as control to treat the PMMA and Flexible Acrylic plates, the percentage of colonies reductions were calculated. In case of using Sage extract solutions, the colonies reductions were 69.75% , 80.80% and 96.16 % respectively for PMMA plates compared with 97.49% reduction for chlorohexidine with mean p-value (0.01) but when the Sage extract solutions 2%, 5% and 10% exposed to Flexible Acrylic, the colonies reductions were 86.55%, 93.67%, 98.06% respectively, compared with 99.83% reduction for chlorohexidine with mean value (0.012). As regard Myrrha extract solutions, the colonies reductions for PMMA plates were 86.41%, 93.59%, 98.46% respectively, compared with 99.81% reduction for chlorohexidine with mean p-value (0.01) but when the Myrrha extract solutions 2%, 5% and 10% exposed to Flexible Acrylic, the colonies reductions were 79.85%, 93.94%, 97.76% compared with 99.63% reduction for chlorohexidine with mean value (0.012).
