Zusammenfassung: | Chlorhexidine (CHX), one of the most effective drugs administered for periodontal treatment, presents collateral effects including toxicity when used for prolonged periods; An inhibition zone test demonstrated that both bacteria were sensitive to the EO; XTT analysis and CFU counts confirmed that 10-folddiluted EO determined a statistically significant (p < 0.05) reduction in bacteria count and viability towards both biofilm and planktonic forms in a comparable manner to those obtained with CHX.. [...]EO exhibited bactericidal activity similar to CHX, but a superior cytocompatibility, making it a promising antiseptic alternative to CHX. Analysis by gas chromatography-mass spectrometry (GC-MS) revealed that the prominent components are menthol, isomenthone, limonene, isomenthanol, menthol acetate, carvone, ß-pinene, apinene, 1,8-cineole, a-terpineol, isopulegol, pulegone, piperiton, piperitone oxide, and ß-phellandrene. The MIC of the M. piperita essential oil was determined against various bacterial strains and varied from 1.13 to 2.25mg/mL; the MIC of Gram-positive bacteria (B. subtilis and S. aureus) was lower than that of Gram-negative bacteria (E. coli, P. aeruginosa, and Pseudomonas fluorescens). |
