Odontogenesis is the tooth formation process involving interactions between the epithelium and ectomesenchyme.
These interactions are genetically determined and highly regulated, resulting in forming dental and periodontal tissues.
The process of dentin formation is called dentinogenesis and occurs by odontoblasts differentiation.
According to some studies, there might be hereditary changes in dentinal development, affecting the organic matrix and its mineralization.

The dentinogenesis imperfecta (DI) is a localized form of mesodermal dysplasia of dentin, which affects both dentitions, occurring most in primary teeth.
With regard to the prevalence, DI signs usually occur in the half number of each offspring with equal frequency between male and female.
There are three types of dentinogenesis imperfecta: Type I (dentinal changes associated with osteogenesis imperfecta presence), Type II (only changes in teeth), and Type III (only the teeth are affected, but with varied clinical findings such as pulp exposures and bell-shaped crowns).
The presence of enlarged pulp chamber was radiographically observed in patients with type III dentinogenesis, different from types I and II.
