In MTA group, specimens showed irregular dentin bridge structures along the pulp-MTA interface, the crystalline-like structures were loosen with lacunas. MTA组可见不规则的牙本质桥结构,晶体样结构沉积于MTA与牙髓的界面上,晶体样结构不连续,但与MTA晶体紧密相连。
Type C: irregular. Reparative dentin increased with an irregular tubular structure after 30 days. C型:不规则结构。30d后,修复性牙本质明显增加。
RESULTS: In calcium hydroxide group and MTA group, specimens showed irregular dentin bridge structures along the pulp-MTA interface. 结果:氢氧化钙组、三氧矿合物组可见不规则的牙本质桥结构。
