Benefits of additional courses of systemic azithromycin in periodontal disease case report.
The strong association of subgingival anaerobic bacteria, such as Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia, with destructive periodontal disease has been well documented in the literature. Several double-blind studies have also shown the beneficial use of systemic antimicrobials that are active against these microorganisms in conjunction with conventional periodontal treatment, especially when periodontal abscesses and/or suppuration upon probing are present. Four cases with periodontal abscesses were treated with scaling/root planing in conjunction with systemic azithromycin. Partial improvement led to retreatment with two additional courses of azithromycin. Bone formation was noted on periapical radiographs after the patients took additional courses of azithromycin. In view of the benefits of using additional courses of azithromycin in the treatment of destructive periodontal disease, we conclude that the single course of systemic antimicrobials currently used in periodontal therapy may be insufficient to reach necessary therapeutic levels in infected sites.
