The crowns of the deciduous teeth are permanent structures which form by incremental growth during the second half of pregnancy and first year of life. These structures become available between the ages of 6 and 12 years with normal exfoliation and can then be studied histologically to demonstrate evidence of metabolic disturbances occurring during tooth development. As the chronology of disturbances can be assessed with reasonable accuracy, such studies provide a potentially valuable research tool.
乳牙的牙冠是永久性结构，在孕期后半段和出生后第一年通过渐进性生长形成。随着正常的乳牙脱落，这些结构在6至12岁之间可用，然后可以进行组织学研究，以证明牙齿发育期间发生的代谢紊乱的证据。由于可以相当准确地评估紊乱的时间顺序，此类研究提供了一个潜在有价值的研究工具。
