Challenges are associated with root canal treatment of teeth affected by DI due to pulp chamber and root canal obliteration, or narrowing of such spaces. If root canal treatment is indicated, it should be done in a similar way like with any other tooth. Further consideration is given for restoring the root-treated tooth as it has weaker dentine which may not withstand the restoration.Preservation of occlusal face height may be tackled by use of stainless steel crowns which are advocated for primary teeth where occlusal face height may be hugely compromised due to loss of tooth tissue as a result of attrition, erosion of enamel.In most cases, full-coverage crowns or veneers (composite/porcelain) are needed for aesthetic appearance, as well as to prevent further attrition. Another treatment option is bonding, putting lighter enamel on the weakened enamel of the teeth and with many treatments of this bonding, the teeth appear whiter to the eye, but the teeth on the inside and under that cover are still the same. Due to the weakened condition of the teeth, many common cosmetic procedures such as braces and bridges are inappropriate for patients with Dentinogenesis imperfecta and are likely to cause even more damage than the situation they were intended to correct.
It is proposed this hearing loss is a secondary feature to attrition; this type of tooth wear can cause jaw overclosure with subsequent changes to the shape of the inner ear, thus causing hearing loss. However, the true cause remains unknown. Type III
Similar clinical and radiographic features to that of type I and II are apparent for the adult (permanent) teeth. The main distinguishing feature is "shell teeth", a term used to describe the unique appearance of the baby (primary) teeth; the primary teeth have multiple pulp exposures and radiographically appear hollow as the dentine layer is thin (dentine hypotrophy) and the pulp chamber is very large. Histology
The enamel has a regular structure, however, there are abnormalities in the structure of dentine and at the amelo-dentinal junction. These abnormalities include:

Fewer dentinal tubules
Dentinal tubules may be of smaller diameter, irregular in shape, and may also be obliterated
Abnormal morphology of apatite crystals
Higher water and collagen content in the organic component of dentine (see Structure section on dentin page to learn more)

Diagnosis
To determine if the condition has been inherited, it is suggested to ask if any other family member has Dentinogenesis imperfecta.
