实验性龈炎的临床观察和龈沟液量的分析

目的　观察实验性龈炎发展过程中的临床表现及龈沟液 (GCF)量的变化 ,探讨GCF量与牙龈炎症发生和发展的关系。方法　选取 11名受试者 ,在其停止口腔卫生措施后 2 1d内 (第 0、7、14、2 1天 )和恢复口腔卫生措施 1周后 (第 2 8天 )记录临床指标的变化 ,并且测量GCF量 (每人测18颗牙 )。结果　在实验性龈炎发展过程中 ,各项临床指标 (菌斑指数、出血指数、牙龈指数、探诊深度 )和GCF量在基线时数值较低 ,停止刷牙后随着菌斑量的不断增多而逐渐上升 ,恢复刷牙后又下降到接近基线水平。GCF量与各项临床指标均为显著正相关。结论　临床指标和GCF量在基线、停止刷牙和恢复刷牙 1周后随菌斑量的改变而存在显著差异 ,反映了牙龈炎症的形成和发展过程

The clinical observations and the measurement of gingival crevicular fluid volume during the experimental gingivitis

Objective To observe the changes of clinical conditions, and measure the GCF volume during the experimental gingivitis in Chinese for studying the relationship between the GCF volume and the development of gingival inflammation Methods 11 young male subjects with healthy gingiva, who had no systemic diseases, were selected for this study GCF samples (18 teeth /person) were collected with strips of filter paper and the clinical parameters were recorded at the baseline (0 day), the 7 th, 14 th, 21 st day (without oral hygiene), and 28 th day (7 days after reestablishing oral hygiene) during experimental gingivitis The GCF volume was measured by weighting Results During the experimental gingivitis, all of the clinical parameters plaque index (PLI), bleeding index(BI), gingival index(GI) and probing index(PD) increased gradually following the plaque assembling, there were significant differences comparing the data of baseline with the data of afterwards without oral hygiene On the 28 th day, the data reduced to the level of baseline rapidly The amount of GCF had the same tendency with the clinical parameters during the experimental gingivitis There was positive correlation between the amount of GCF and clinical parameters Conclusion The amount of GCF can reflect the development of gingival inflammation
