Analysis of periodontal systematic therapy-clinical effects on patients with generalized aggressive periodontitis of 5 years

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.
