Abstract
In the present study, jle antimicrobial activity of the essential oils from clove (Syzygiurn aromaticum (L.) Merr. et Petry) against different Gram positive, Gram negative microorganisms found in the oral cavity in periodontal infections such as Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis and Candida albicans and organisms isolated from tooth tartar of dental patients was evaluated. Minimum inhibitory concentrations (MR's) were determined against three dental clinical isolates of Staphylococci, Streptococci, and Streptobacilli which ranged from 1.25-5 uL/mL and against reference strains which ranged from 0.625-160 pl,/mL. The minimum microbicidal concentrations (MMCs) of the clove essential oil for clinical isolates ranged from 2.5-101.11_,/mL and for the reference strain varied from 1.25-320 pL/mL. Clove oil exhibited prominent antimicrobial activity against all the test microorganisms especially organisms isolated from tooth tartar of dental patients proving its effectiveness in various periodontal diseases.
