- Not associated with osteogenesis imperfecta
- Mutation in gene – DSPP – dentin sialo phospho protein
- DSPP located on chromosome number 4
- Revised shield classification
- Common traits seen in both types
- Flat DEJ line
- Gene = DSSP
- Common traits seen in both types
| Type 1 Opalescent dentin type | Type 2 Brandy white type |
 Bulbous crowns are seen With cervical constriction Giving tulip shaped crownsWHY? Because of atypical dentin formation = obliteration of pulp chambers |  Large sized pulp chambers Very thin dentin – hence, radiographically SHELL TEETH |
