Study Notes
Tooth Germ Development
- Three additional structures are formed in the enamel organ during the cap stage.
Ameloblasts
- During the deposition of enamel and dentin of the developing crown, the nuclei of ameloblasts are positioned close to the stratum intermedium layer of the enamel organ.
Ectomesenchyme
- The ectomesenchyme provides inductive signals that guide tooth morphogenesis during tooth germ development.
Tooth Germ Stages
- The presence of condensed ectomesenchyme located directly under the tooth bud indicates the transition from bud to cap stage in tooth germ development.
