摘要
目的:比较双线排龈和单线排龈对基牙龈沟液含量和成分的影响。方法:对47位患者的94个牙行冠桥修复,采用同一患者的不同牙位对照,分别采取双线排龈法和单线排龈法,取印模,完成修复体。于修复后7、21 d和3、6个月提取受试牙位龈沟液,称重并检测其中天冬氨酸转氨酶(AST)和碱性磷酸酶(ALP)含量。结果:修复后7 d,单线排龈组龈沟液量、GCF-AST和GCF-ALP含量高于双线排龈组(P<0.05);修复后21 d、3个月,两组各项牙周指标之间无显著性差异(P>0.05);修复后6个月,单线排龈组龈沟液含量高于双线排龈组(P<0.05),GCF-AST和GCF-ALP含量有所升高但差异无统计学意义(P>0.05)。结论:双线排龈法对牙周组织的影响较单线排龈法小,更有利于牙周组织的健康。
AIM： To study the effects of double gingival retraction and gingival retraction before impression on the quantity and components of gingival crevicular fluid（GCF）. METHODS： 94 teeth in 47 patients were treated by fixed prosthetics. Double gingival retraction was applied on one side and gingival retraction was applied on the other side in each patient. The quantity of GCF and the content of aspartate aminotransferase（AST） and alkaline pbosphatase （ALP） in GCF were assessed at 7 and 21 d, 3 and 6 months after application of the prosthetics. RESULTS ： 7 d after treatment the quantity of GCE and the content of AST and ALT in the gingival retraction group were higher than those in double gingival retraction groupe （P 〈 0. 05 ）. The measurements were not statistically different between the two groups at 21 d and 3 months after treatment （P 〉 0.05）. 6 months after treatment the GCF in gingival retraction groupe was more than that in double gingival retraction groupe, while AST and ALT content was not statistically different be- tween the two groups （P 〉 0.05 ）. CONCLUSION： Double gingival retraction has less effect on periodontal tissues than gingival retraction.
