Abnormalities of the pulp chamber is the main characteristic to make a definitive diagnosis. [ 15 ] [ 16 ] In the primary teeth, coronal dentin dysplasia may appear similar to Dentinogenesis Imperfecta type II (DG-II) but if abnormalities features appear to be more pronounced in the permanent teeth, then consider changing the diagnosis to DGI ...
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.

The pulp is the neurovascular bundle central to each tooth, permanent or primary.It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth. [2]
Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.
The pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain. A tooth can be relieved from pain if there is irreversible damage to the pulp, via root canal treatment. Root canal anatomy consists of the pulp chamber and root canals. Both contain the dental pulp.
Free pulp stones are found within the pulp tissue and is the most common encounter. The size vary from 50μm in diameter to several millimetres and may occlude the entire pulp chamber. Embedded pulp stone is fully embedded in dentine and most commonly found in the apical portion of the root.
Dental pulpal testing is a clinical and diagnostic aid used in dentistry to help establish the health of the dental pulp within the pulp chamber and root canals of a tooth. . Such investigations are important in aiding dentists in devising a treatment plan for the tooth being test
In vertebrates, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root.
