Abstract:
:This study evaluated the susceptibility of oral pathogenic microorganisms Candida albicans, Streptococcus mutans, Staphylococcus aureus, and Aggregatibacter actinomycetemcomitans to Brazilian medicinal plant extracts of Schinus terebinthifolius (aroeira), Croton campestris (velame), Lafoensia pacari (pacari), Centaurium erythraea (centáurea), Stryphnodendron adstringens (barbatimão), and Anacardium humile (cajuzinho-docerrado), as compared to standardized antimicrobial agents (nystatin, chloramphenicol and tetracycline hydrochloride). Ethanol, hexane and butane fractions from stem barks, rinds, leaves, and/or roots were extracted and tested. Antimicrobial diffusion agar test and MIC were performed according to CLSI. After 24 h of incubation at 37 °C, the diameter of inhibition zones and spectrophotometer readings were measured and compared. The results were reported as means ± standard deviation (M ± SD). With the exception of five extracts that showed no antimicrobial activity, all the extracts tested showed antimicrobial activity, in different levels. This study suggests that extracts from the plants tested could be an alternative therapeutic option for infectious conditions of the oral cavity, such as denture stomatitis, dental caries, and periodontitis.
