1. Bud stage:

i. Characterised by formation of tooth bud. The epithelial cells begin to proliferate into the endomesenchyme of the jaw

2. Cap stage-

	i. Condensation of ectomesenchyme adjacent to the tooth bud & beginning of histodifferentiation.
	ii. Enamel organ & dental papilla are formed.
	iii. Tooth germ OEE, lEE, dental papilla, Dental sac, stellate reticulum

3. Bell Stage

	i. Crown shape is determined in bell stage
	ii. Early Formation of epithelial pearls beginning of crown formation

4. Advanced Bell stage-
