摘要: 目的分析牙龈蛋白K(gingipain K,Kgp)在正畸治疗中对牙龈炎性反应的影响。方法选择青少年牙龈健康者45例,分别取矫治器戴入前与矫治器戴入后3个月的龈沟液,应用16S rDNA PCR技术检测各样本中的牙龈卟啉单胞菌(P.g)及Kgp,采用SPSS17.0软件包对数据进行统计学分析。结果矫治器戴入前Kgp检出率为35.71%,矫治器戴入后Kgp检出率为67.86%,两者之间差异显著(P<0.05)。结论正畸治疗患者在矫治器戴入后Kgp检出率增加,出现牙龈炎性反应。

Abstract: PURPOSE: To explore the correlation between gingipain K (Kgp) and inflammatory reaction of gum in the process of orthodontic treatment, and analyse the role of Kgp in the development of gingivitis during orthodontic treatment. METHODS: Totally 45 orthodontic healthy teenagers were randomly chosen for the study. The subgingival plaques were collected simultaneously before orthodontic treatment and 3 months after treatment. 16S rDNA PCR technique was used to detect Porphyromonas gingivalis (P.g) and Kgp. SPSS17.0 software package was used for statistical analysis. RESULTS: The detection rate of Kgp was 35.71% before orthodontic treatment and 67.86% after treatment. Positive correlation (P<0.05) was observed between Kgp and gingival inflammation. CONCLUSIONS: Fixed orthodontic appliances cause plaque accumulation, accordingly slight gingiva inflammation and the increament of P.gingivalis in the early stage.
