Bud Stage:
This occurs at the beginning of the eighth week of prenatal development for the primary dentition.
This stage is mainly characterised by the appearance of a tooth bud without the clear arrangement of cells. The tooth bud itself is the group of the cells at the end of the dental lamina. The stage is named for the extensive proliferation into bds. Each of these buds from the dental lamina, together with the mesenchyme will develop into a tooth germ. The important point to note is that only the proliferation of the two tissues occurs during this stage.
