Evaluation of Antibiotic Drug Synergisms Against Periodontal Aggregatibacter Actinomycetemcomitans
Objectives: Aggregatibacter actinomycetemcomitans is major putative bacterial pathogen in human periodontitis, particularly in aggressive periodontitis in younger-aged individuals. Systemic administration of certain antibiotics in combination have been demonstrated to exert synergistic …
