摘　　要：目的观察龈上洁治术后临床指标及龈沟液中牙龈卟啉单胞菌含量的变化。方法选取30例慢性龈炎患者,采集洁治术前、后患牙的龈沟液,以健康的第一磨牙为对照,应用电化学测菌法分别检测治疗前后龈沟液中牙龈卟啉单胞菌的数量,同时记录临床指标,包括菌斑指数、牙龈指数、探诊深度。结果龈上洁治术前患牙与健康对照牙龈沟液牙龈卟啉单胞菌的绝对数量有显著差异性(P<0.05);龈上洁治术后慢性龈炎患者临床指标菌斑指数、牙龈指数、探诊深度均有明显下降(P<0.05);龈上洁治术后龈沟液中牙龈卟啉单胞菌的绝对数量亦有明显下降(P<0.05)。结论龈沟液内牙龈卟啉单胞菌含量变化临床指标一致,可以反映洁治效果。Objective To determine the P. gingivalis levels in gingival crevicular fluid before and after supragingival scaling by electrochemical method. Methods Thirty patients with chronic gingivitis were included in this study. Electrochemical method was used to test P. gingivalis changes in gingival crevicular fluid before and after supragingival scaling. The periodontal clinical parameters including plaque index, gingival index, probing depth and clinical attachment level were also recorded. The healthy first molar served as control. Results The absolute number of P. gingivalis before scaling was higher in the affected teeth than in healthy first molar, but not significantly different after scaling. The periodontal clinical parameters improved obviously after scaling. The absolute number of P. gingivalis decreased after scaling compared with prescaling. Conclusion Supragingival scaling could decrease the P. gingivalis level.
