In the coronal type, teeth show normal roots containing enlarged pulp with abnormal extensions towards the roots, which is often described as “thistle tube” shaped on dental radiographs. As well as this, numerous pulp stones can often be found in the pulp chambers due to abnormal calcifications. [15]
Thistle funnels are used to add small volumes of liquids to an exact position. Thistle funnels are found with or without taps. The thistle tube shaft is designed to allow insertion through a small hole present in some stoppers , permitting the tube to be inserted into a container such as an Erlenmeyer flask .
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 ...
Filter funnels have a neck of a thin capillary tube and ribs which increase the filter-papers' effectiveness and thus accelerate the process of filtering. [1] Powder funnels have a short and wide neck for fast pouring of powders. Separatory funnels are pear-shaped, have a cap and a short neck, with a stopcock for the even pouring of fluids ...
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.
The main distinguishing feature is "shell teeth", a term used to describe the unique appearance of the baby (primary) teeth; the primary teeth have multiple pulp exposures and radiographically appear hollow as the dentine layer is thin (dentine hypotrophy) and the pulp chamber is very large. [2] [3] [4] [14]
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.
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
