Clinical effects of periodontal -sequence treatment on severe generalized aggressive periodontitis

Objective:To investigate the clinical results of periodontal-sequence treatment of generalized aggressive periodontitis in a Chinese population.Method:Fifteen patients aged(24.6±4.0)years with generalized aggressive periodontitis were included in this prospective study.All subjects received scaling and root planing and photodynamic therapy(PDT),re-evaluation after four weeks,as the case for flap surgery or bone graft,clinically monitored every 3months for 12 months.The clinical parameters,including probing depth(PD),bleeding on probing(BOP)and mobility,furcation involvement of molars were recorded at baseline,3,6,9 and 12 months after treatment.Result:At baseline,the mean PD of patients was(3.96±2.21)mm,the percentage of BOP positive sites was 88.1 %.At 12 months after surgery,the mean pocket depth reduction was 1.6 mm,the percentage of BOP positive sites reduced to 8.7 %.There was a statistically significant decrease of mild,moderate and severe sites the PD after treatment(P 0.05).Conclusion:Periodontal-sequence treatment is effective for the generalized aggressive periodontitis and every 3 months SPT is necessary for maintenance.
