Where, A = the lowest point of the pulp chamber roof, B = the highest point of the pulp chamber floor, and C = the longest root’s apex. Using this formula, a tooth is a taurodont if the landmark ratio is ≥ 0.2 and the distance from the highest point of the pulp chamber floor (B) to the cemento-enamel junction (D) is ≥ 2.5 mm. The full ...
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.
Treatment options are nonsurgical root-canal re-treatment or periradicular surgery. Although accessing and cleaning the pulp chamber and canals would be easier with the former, it is contraindicated in some patients. [2] The stages of periradicular surgery are: Local anaesthesia; Flap design; Bone removal; Curettage; Apicectomy
Pulp canal obliteration (also termed pulp chamber obliteration [1] or root canal obliteration) [1] is a condition which can occur in teeth where hard tissue is deposited along the internal walls of the root canal and fills most of the pulp system leaving it narrowed and restricted. [2]
Indirect restorations are contraindicated in patients under 16 as the pulp chamber is still large and wide dentinal tubules increase the stress on the pulp. When preparing a cavity to retain an indirect restoration there is a risk of damage to the nerve supply of a vital tooth.
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]
[5] [12] However, when the tooth concerned will undergo endodontic treatment such as root canal treatment, presence of large pulp stones will be clinically significant. [12] [13] Large pulp stones in the pulp chamber might block the access to canal orifices and prevent the exploring dental instruments from passaging down the canal. [12]
