目的探讨胶原酶对脱矿后的人牙根面牙本质胶原蛋白的降解作用。
Objective the purpose of this study was to evaluate the effect of degradation of human root dentin collagen treated with collagenase after demineralization.
牙本质基质蛋白(DMP)- 1是骨、软骨、釉质、牙骨质和牙本质生物矿化所必需的一种酸性非胶原蛋白。
Dentin matrix protein (DMP) -1 is an acidic non-collagenous protein that is necessary for the proper biomineralization of bone, cartilage, cementum, dentin and enamel.
结论：胶原酶的化学本质是蛋白质，任何能改变蛋白质性质的条件，都会使酶的活性下降或失活。
Conclusion: Collagenase is protein in chemical nature. Any conditions which change protein's character can lead to enzyme's activity declined or lost.
结论：胶原酶的化学本质是蛋白质，任何能改变蛋白质性质的条件，都会使酶的活性下降或失活。
Conclusion: Collagenase is protein in chemical nature. Any conditions which change protein's character can lead to enzyme's activity declined or lost.
