1.Study the first stages of tooth development:
- stratified oral epithelium of the embryo made up of larger clear cells is connected with the enamel organ by the narrow epithelial cord (dental lamina);
- the enamel organ is a clear two-walled dental cap with stellate reticulum in the central part;
- underneath the dental cap there’s a dental papilla (originating from mesenchima) joining the enamel organ;
- find trabeculae of bone of the forming alveolar wall (reticulofibrous bone tissue) in the embrionic connective tissue surrounding the tooth
2. Draw and sign:
1 - oral epithelium,
2 - dental lamina,
3 - the enamel organ,
4 - stellate reticulum,
5 - dental papilla,
6 - trabeculae of bone.
3. Define and write significant features of the sample preparation and how the tooth originates and develops from the tooth germ
