In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
Sharp, shooting pain when you eat or drink something cold, hot, sweet or sour, or when you put pressure on the tooth could be a sign of a cavity, cracked tooth or even an exposed tooth root, per JADA.
[3] [4] This problem has not been realised with one study showing long-term data beyond five years, to when the baby teeth are lost, with fewer problems from the tooth with the crown. Crowns placed using the Hall Technique have better long term outcomes (pain/infection and need for replacement) compared with standard fillings. [5] [6] [7]
A crown is used to cover a tooth and may be commonly referred to as a "cap." Traditionally, the teeth to be crowned are prepared by a dentist, and records are given to a dental technician to construct the prosthesis. The records include models, which are replicas of a patient's teeth, and the impressions used to make these models.
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy , root resection , repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
The post does not play any role in reinforcing or supporting the tooth and can in fact make it more likely to fracture at the root. [3] When deciding whether or not a tooth requires a post and core crown rather than a conventional crown, the following must be established: [4] Presence of an adequate ferrule (coronal tooth structure)
