Abstract: Abstract：Objective To study the clinical effect on patients with generalized aggressive periodontitis who accepted periodontal systematic therapy for 5 years. Methods Ten patients with generalized aggressive periodontitis were selected in the Periodontology and Oral Mucosa Department，Stomatological Hospital of Dalian from January 2006 to January 2007. These patients accepted periodontal systematic therapy for 5 years，including：periodontal initial therapy，periodontal surgical therapy，and periodontal supportive therapy. Clinical parameters of probing depth(PD)，clinical attachment level(CAL)，tooth mobility(TM)and bleeding on probing(BOP)were recorded by Florida electronic probe at baseline and 1-5 years after therapy，then analysis was carried out. Panoramic tomogram and the first molar intraoral radiography were detected before and 5 years after therapy. Results PD and CAL were decreased 1-5 years after periodontal systematic therapy，the positive sites of BOP were reduced and TM was improved. The statistical differences were detected(P < 0.01). The positive sites of BOP were reduced in the 5th year than in 1-3years，and the statistical differences were detected(P < 0.05). Conclusion To generalized aggressive periodontitis，the effect of periodontal systematic therapy of 5 years is effective and stable.
