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
