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.
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]
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]

Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
Fused teeth tend to have separate pulp chambers and root canals, unlike in tooth gemination which tends to have a single pulp chamber and root canal.However, the degree of separation will depend on where & when the fusion occurred so the pulp chamber and/or root canal may be completely fused into one.
The pulp is the location of the nerve and blood supply of a tooth. In the deciduous maxillary central incisor, endodontic treatment is less frequent. In the permanent maxillary central incisor, root canal treatment can be effective. There frequently are three pulp horns in this tooth. [11]
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.
