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]
A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
In the case of an infection breaching the dentin to or very near the pulp, or in the instance of odontoblast death due to other attack (e.g. chemical or physical), undifferentiated mesenchymal cells can differentiate into odontoblast-like cells which then secrete another type, reparative dentin, underneath the site of attack.
It is completely covered in enamel. The term "clinical crown" often is convenient in referring to any part of the tooth visible in the mouth, but as a rule the unqualified term "crown" refers to the anatomic crown. The bulk of the crown is composed of dentine, with the pulp chamber within.
Dentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp. [15] The formation of dentin is known as dentinogenesis. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water by weight. [16]
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 tooth gemination, the pulp chambers and root canals tend to be joined, unlike in tooth fusion where they tend to be separate. However, the degree of separation will depend on the stage of tooth development when the gemination occurred, so the pulp chamber and/or root canal may or may not be involved. [1]
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 ...
