目的：探讨正畸对口腔龈沟内牙周菌群的影响。方法固定矫治的62例恒牙列患者作为研究对象，对其正畸前及正畸6个月后龈沟内的细菌变化、口腔细菌的检出率进行对比。结果①牙龈沟内牙周菌群：本组患者正畸6个月后球菌水平显著低于正畸前，差异有统计学意义(P<0.05)；螺旋体及梭状菌水平显著高于正畸前，差异有统计学意义(P<0.05)。②口腔菌群：本组患者正畸6个月后，卟啉单胞菌的检出率显著高于正畸前，差异有统计学意义(P<0.05)。结论正畸后口腔龈沟内螺旋体、梭状菌及卟啉单胞菌可见明显升高，临床应给予足够的重视，以此保障正畸健康的牙周。

Objective To investigate influence of orthodontics on periodontal flora in oral cavity and gingival sulcus. Methods There were 62 permanent dentition patients receiving fixed orthodontic treatment as study subjects. Comparison was made on bacteria change in gingival sulcus and detection rate of oral cavity bacteria before and after 6 month of orthodontics. Results ①Gingival sulcus periodontal flora:After 6 month of orthodontics, these patients had much lower coccus level than that before orthodontics. The difference had statistical significance (P<0.05). They had much higher spirochete and clostridium bacteria levels than those before orthodontics, and the difference had statistical singficance (P<0.05).②Oral bacteria:After 6 month of orthodontics, they had obviously higher detection rate of porphyromonas gingivalis than that before orthodontics. The difference had statistical significance (P<0.05). Conclusion Spirochete, clostridium bacteria, and porphyromonas gingivalis had obvious increase in oral cavity and gingival sulcus after orthodontics. Clinical attention is essential for guarantee periodontal health.
