Furcation perforations created in the pulpal floors of 30 extracted human molars were repaired with either light-cured glass ionomer cement (GI), calcium phosphate cement (CPC), or light-cured glass ionomer cement placed over a CPC matrix (M). After the cement was set, the teeth were immersed in India Ink for 48 h, dried, and sectioned longitudinally. Dye penetration into the furcation repair was independently evaluated by three board-certified endodontists. There was no significant difference in the mean extent of dye leakage among the three experimental groups. The use of CPC, with its enhanced biocompatibility, potential for osteoconduction, and sealing ability, may improve the prognosis of teeth with furcation perforations.
在30颗拔除的人磨牙的髓室底制备根分叉穿孔,分别用光固化玻璃离子水门汀(GI)、磷酸钙水门汀(CPC)或置于CPC基质(M)上的光固化玻璃离子水门汀进行修复。水门汀凝固后,将牙齿浸入印度墨水中48小时,干燥后纵向切片。由三名获得委员会认证的牙髓病医生独立评估染料渗入根分叉修复处的情况。三个实验组之间染料渗漏的平均程度没有显著差异。CPC具有增强的生物相容性、骨传导潜力和封闭能力,使用它可能会改善根分叉穿孔牙齿的预后。
