Methods Collected 25 extracted teeth with shallow dentin caries in 5 age groups, each group 5 teeth.
方法收集5组不同年龄组含有牙本质浅层龋的离体牙，每组各5颗牙齿。
Objective:To explore the causes of dentin caries by assay of the content of organic acids in carious dentin.
目的：通过对牙本质龋中有机酸含量的测定，探讨牙本质龋形成原因。
Objective: To analyze the content of calcium in enamel and dentin of deciduous teeth and study their relationships with caries status.
目的：分析探讨乳牙釉质、牙本质钙含量状况与龋病关系。
AIM: To investigate the relationship between the distribution, content of calcium in deciduous dentin and caries susceptibility in children.
目的：探讨钙元素在乳牙牙本质内的分布及其与龋病易感性之间的关系。
CONCLUSION: Chinese nutgall can inhibit collagen degradation and affects the further demineralization in dentin matrix, which consequently inhibit the advanced dentine caries.
结论：五倍子能抑制胶原分解，对脱矿的进一步进行产生影响，从而使牙本质龋的进展受到抑制。
