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 ...
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 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]
To eliminate bacteria from the pulp chamber and root canals, the use of efficient antiseptics and disinfectants is necessary. [10] The soft tissues are either drilled out of the root canal(s) with engine driven rotary files, or with long needle-shaped hand instruments known as hand files (H files and K files).
Preventive efforts can limit pathology occurring within the pulp, which may render future endodontic procedures less challenging, with better outcomes. Challenges are associated with root canal treatment of teeth affected by DI due to pulp chamber and root canal obliteration, or narrowing of such spaces.
Regenerative endodontics is founded by the seminal work by Dr. Ostby in the early 1960s. He hypothesized that the presence of blood clot within the root canal promotes healing of the pulp, hence maintaining the vitality of the pulp. This can be quite similar to the role of blood clot in other injury site in the healing process.
An access opening is made to reach the pulp chamber; A file is placed in the root canal and a radiograph is taken to establish the root length. Care should be taken to avoid pushing instruments through the apex; Remnants of the pulp are then removed using barbed broaches and files; The canal is flushed with hydrogen peroxide to remove debris ...
Pulp tests (test results of immature teeth can be misleading, as they are known to give unreliable results) [1] Check and see if there is an elevated, flat wear facet on the occlusal surface of the tooth [1] Test cavity which has an absence of pain sensation and has an empty pulp chamber/ canal. [1]
