摘要:目的 观察极固宁TM涂布于金属烤瓷全冠活髓基牙牙预备体表面21 d对牙髓组织学形态的影响。方法 选择因正畸治疗需要而计划拔除的20颗前磨牙进行金属烤瓷全冠牙体预备，其中每2颗牙均为同颌同名牙；采用随机、双盲、自身对照设计分为2组：对照组在牙预备体上直接用氧化锌丁香酚水门汀粘固暂时冠；观察组在牙预备体上涂布极固宁TM后用氧化锌丁香酚水门汀粘固暂时冠。所有牙分别于牙体预备后21 d拔除，常规组织病理切片，HE染色，显微镜下观察评价牙髓组织反应。结果活髓基牙经金属烤瓷全冠牙体预备21 d时，对照组和观察组的牙髓组织反应无明显差别(P>0.05)。牙髓组织的反应程度与牙预备体的剩余牙本质厚度(RDT)有关；RDT分别为491.76，503.88和487.32 μm的3个样本观察到修复性牙本质的形成。结论 在本实验条件下，金属烤瓷全冠牙预备体表面涂布极固宁TM21 d对活髓基牙的牙髓组织无明显影响。关键词: 抗变态反应药； 金属烤瓷合金； 牙冠(假体)； 牙本质； 牙髓

ABSTRACT: Objective To observe vital pulp response after 21 days of Green Or applied to the surface of PFM crown preparations.Methods 20 human biscuspids scheduled to be extracted for the orthodontic reasons were prepared for porcelain fused to matal(PFM) crown,of which every 2 teeth were from the same patient and the same jaw. The teeth were randomly ......
