目的:观察重度广泛型侵袭性牙周炎(generalized aggressive periodontitis,GAgP)患者牙周序列治疗后临床指标的变化,并评价其治疗效果。方法:15例GAgP患者在龈上洁治后1个月内完成龈下刮治、根面平整及光动力治疗,刮治后4周再评估,行翻瓣及翻瓣植骨术,每3个月进行1次牙周维护,序列治疗后纵向观察12个月。在基线和维护期各时间点记录全口探诊深度(probing depth,PD)、探诊出血(bleeding on probing,BOP)和牙齿松动度,磨牙记录根分叉病变的程度。结果:在基线时患者平均PD(3.96±2.21)mm,BOP阳性位点占88.1%。序列治疗后12个月平均PD(2.36±1.28)mm,BOP阳性位点减少至8.7%,其中轻、中、重度位点治疗后PD值与治疗前比较差异有统计学意义(P<0.05)。结论:GAgP患者经牙周序列治疗和定期牙周维护能取得良好的治疗效果。
OBJECTIVE: To observe the change of clinical indexes after periodontal treatment of patients with severe generalized periodontitis (GAgP) and to evaluate its therapeutic effect. Methods: Fifteen patients with GAgP were treated by subgingival scaling, root surface formation and photodynamic therapy within one month after supragingivalgia. Four weeks after the curettage, they were re-evaluated and the flap and flap were replanted every 3 Periodontal maintenance was performed once a month, followed by longitudinal observation for 12 months after treatment. The probing depth (PD), bleeding on probing (BOP) and tooth mobility were recorded at each time point during baseline and maintenance period, and the extent of root bifurcation was recorded in molars. Results: At baseline, patients had an average PD of 3.96 ± 2.21 mm with a positive BOP score of 88.1%. The average PD (2.36 ± 1.28) mm and the BOP positive site decreased to 8.7% at 12 months after treatment. The PD values of the mild, moderate and severe sites after treatment were significantly different from those before treatment (P <0.05) . Conclusion: GAgP patients with periodontal treatment and regular periodontal maintenance can achieve good therapeutic effect.
