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] Because of the continuous deposition of the dentine, the pulp chamber becomes smaller with the age. This is not uniform ...
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]
Procedures for root canal. The space inside the root canals is filled with a highly vascularized, loose connective tissue, called dental pulp. The dental pulp is the tissue of which the dentin portion of the tooth is composed. The dental pulp helps complete formation of the secondary teeth (adult teeth) one to two years after eruption into the ...
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 ...
Some locks have more than one chamber, often of different dimensions. These locks provide the essential infrastructure that allows tows to "stair-step" their way through the system and reach distant inland ports such as Minneapolis, Chicago, and Pittsburgh. The locks can generally be categorized by three different sizes, as expressed by length.

Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Regenerative endodontics instead seeks to replace live tissue in the pulp chamber. The ultimate goal of regenerative endodontic procedures is to regenerate the ...
Proposed by Governor of New York De Witt Clinton, the Erie was the first canal project undertaken as a public good to be financed at public risk through the issuance of bonds. [9] When the project was completed in 1825, the canal linked the Hudson River to Lake Erie via 83 separate locks and over a distance of 363 miles (584 km).
