SOD与SOD复合Ca(OH)_2切髓术的组织学疗效对比

Histological comparison on pulpotomy with superoxide dismutase(SOD) and SOD complex calcium hydroxide

目的：观察超氧化物岐化酶（ＳＯＤ）、ＳＯＤ复合氢氧化钙〔Ｃａ（ＯＨ）２〕（ＣＨ）作为盖髓剂的组织学疗效。方法：将ＳＯＤ、ＳＯＤ复合Ｃａ（ＯＨ）２用于猴磨牙切髓术，观察组织学效果。结果：术后６个月，均可诱导牙本质桥形成，但组织学效果不同，ＳＯＤ组以骨样牙本质为主；ＳＯＤ复合Ｃａ（ＯＨ）２组以典型规则的管样牙本质为主；对照组Ｃａ（ＯＨ）２以不规则管样牙本质和骨样牙本质为主。结论：ＳＯＤ复合Ｃａ（ＯＨ）２在诱导牙本质桥形成的组织学效果方面优于单纯使用ＳＯＤ。

Aim: The tissue reactions of pulpotomy with SOD and SOD complex CH were observed. Methods: Teeth of monkeys, whose dental pulp wee exposed to vital pulpotomy, were capped with SOD, SOD-CH paste respectively. The pulp reactions were observed by histological examination. Results: By histological observation, complete dentin brigde was formed in all groups, in SOD group mainly was osteodentin, in SOD-CH group was regular dense tubular dentin, in CH group was irregular tubular dentin. Condusions: The effect of SOD complination was better than that of SOD used alone.
