本实验通过对狗下颌前磨牙牙冠的实验操作，从放射学和组织学两方面研究了牙齿在萌出中的作用。在计划萌出之前，将牙冠移除，并将死冠壳或金属或硅胶复制品替换到牙囊中。这些替代物在通常的萌出途径形成和骨隐窝基部的骨小梁形成后按计划萌出。去除牙冠，但不添加替代物，也表现出这些相同的喷发特征。牙齿萌出是牙槽骨中的一系列代谢事件，其特征在于牙囊两侧的骨吸收和形成，而牙齿并不参与这一过程。
The role of the tooth in eruption was studied radiographically and histologically after experimental manipulations of the crowns of permanent mandibular premolars in dogs. Crowns were removed and dead crown shells, or metal or silicone replicas were substituted into dental follicles just prior to scheduled eruption. These replacements erupted on schedule after formation of the usual eruption pathways and formation of trabecular bone from the base of the bony crypt. Removal of crowns, but without adding replacements, also exhibited these same hallmarks of eruption. Tooth eruption apparently is a series of metabolic events in alveolar bone characterized by bone resorption and formation on opposite sides of the dental follicle, and the tooth does not contribute to this process.
