| What are the 4 stages of development? | 1. Bud 2. Cap 3. Bell 4. Crown |
| What are two phenomena that occur in the cap stage? | 1. The initiation of the permanent tooth dental lamina (secondary dental lamina) begins lingual to the developing primary tooth. 2. The formation of the tooth germ occurs. |
| Name the 3 parts of the tooth germ. | 1. Enamel Organ (derived from ectoderm) 2. Dental Papilla (derived from ectomesenchyme) 3. Dental Sac (derived from ectomesenchyme) |

| What are Glands or Pearls of Serres? | Residual dental lamina cells. They have the ability to form odontogenic cysts in later life. |
| Contact between the dental sac cells and the dentinal cells causes the dental sac cells to differentiate into what kinds of cells? | Fibroblasts- form PDL Cementoblasts- form cementum Osteoblasts- form alveolar bone |
| What are Rests of Malassez? | Any remnant cells of Hertwig's Root Sheath caught within the PDL. They have the ability to form odontogenic cysts later in life. |
