Aggressive periodontitis, although not rare, is a fairly unknown condition. Little is known about its optimal management. While majority of patients with common forms of periodontal disease respond predictably well to conventional therapy (oral hygiene instructions (OHI), non-surgical debridement, surgery, and Supportive Periodontal therapy (SPT)), patients diagnosed with aggressive form of periodontal disease often do not respond predictably/favorably to conventional therapy owing to its complex multi-factorial etiology. Protocols for treating aggressive periodontitis are largely empirical. There is compelling evidence that adjunctive antibiotic treatment frequently results in more favorable clinical response than conventional therapy alone. This article mainly focuses on the role of adjunct use of pharmacological agents in improving the prognosis and treatment outcome of aggressive periodontitis patients.
