Abstract:
Objective:To study the antimicrobial susceptibility of periodontopathic bacteria associated with failing implants to commonly used antibiotics in periodontal therapy and dental practice.Methods:Antimicrobial susceptibility of bateria isolates was determined by the method of microbroth dilution and the activities of 8 kinds of antibiotics against international laboratory strains and clinical isolates of Provotella intermedia (Pro.I), Porphyromonas gingivalis (Pg), Actinobacillus actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn) were examined.Results:Ofloxacin, clindamycin, tinidazole and metronidazole showed stronger antibacterial activity aginst Pro.I,Pg,Aa and Fn with MIC_ 90 ≤0.5 ?g/ml and MBC_ 90 ≤0.5 ?g/ml.Conclusion:Commonly-used antibiotics are potential against bacteria isolated around failing implants.
