| 摘 要： | 目的:探讨钙离子在牙体硬组织中的迁移规律。方法:实验室观察24 h内新鲜的完整无龋的离体人牙在牙齿表面电位的影响下,牙冠牙釉质、牙根牙骨质、牙髓牙本质三者之间钙离子的迁移规律。结果:牙釉质池浸泡液中钙离子浓度大于牙骨质池、牙本质池浸泡液中钙离子浓度,且高于母液的钙离子浓度;后两者钙离子浓度均小于母液的钙离子浓度。经方差分析两两间P<0.01有显著性差别。结论:牙体硬组织中钙离子的迁移规律为:牙骨质→牙本质→牙釉质。 |

| Abstract: | Objective:To study the movement regularity of Ca~(2 ) in tooth hard tissue.Methods:14 extracted intact caries-free teeth were cleaned and then immersed into artificial saliva in a divice with 3 chambers for enamel part,dentin part and cement part respectively.The concentration of Ca~(2 ) in the chambers was measured with an ion meter,TECHNICON(AXON,USA),24 h after immersion of each tooth.Results:The Ca~(2 ) concentration in tooth immersed fluid of enamel part was higher than that of dentin part(P<0.01),cement part(P<0.01) and artificial saliva(P<0.01) respectively,however the Ca~(2 ) concentrations of the dentin part and the cement part were lower than that of the artificial saliva(P<0.01).Conclusion:The movement of Ca~(2 ) in tooth hard tissue may be from cement to dentin and from dentin to enamel. |
