摘　　要：目的探讨固定矫治病人矫治前后龈沟液量与牙周健康状况的关系。方法选取接受直丝弓矫治技术治疗的病人24例,以右上颌第一磨牙(16)、左上颌中切牙(21)、左下颌第一前磨牙或第二前磨牙(34或35)、右下颌中切牙(41)4个牙位为检测牙位,分别于矫治前和矫治1、3个月时,检测其龈沟液量、菌斑指数、牙龈指数和探诊深度。结果固定矫治1个月和3个月时,病人的菌斑指数、牙龈指数和龈沟液量均较矫治前显著升高,差异有显著性(F=4.729～37.058,P<0.05);探诊深度矫治3个月时较矫治前和矫治1个月升高,差异有显著性(F=12.974,P<0.05)。龈沟液量与菌斑指数、牙龈指数、探诊深度之间存在明显的正相关关系(r=0.288～0.503,P<0.05)。结论龈沟液量检测是一种简单有效的评价固定矫治病人牙周健康状况的指标。Objective To observe the relationship between gingival crevicular fluid volume and periodontal health condi- tion, before and after fixed orthodontic treatment. Methods Twenty-four patients wearing a straight wire appliance were in eluded in this study. The right maxillary first molar （16）, left maxillary central incisor （21）, left mandibular first molar and right mandibular central incisor （41） were selected to be checked. The gingival erevieular fluid, plaque index, gingival index, and depth of probing were measured before and at one and three months after the treatment. Results At one and three months of the treatment, the plaque index, gingival index and the volume of gingival crevicular fluid in the patients increased significantly as compared with before treatment （F= 4. 729-37. 058,P〈0.05） ; while probing depth significantly increased at three months of treatment （F= 12. 974 ,P〈0.05）. The amount of gingival crevicular fluid was positively correlated with plaque index or gingival index or probing depth （r=0. 288-0. 503 ,P〈0.05）. Conclusion The amount of gingival crevicular fluid is a simple and effective parameter to evaluate the periodontal health condition of patients undergoing fixed appliance therapy.
