Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain. One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament ...
In cases of a simple enamel fracture, the recommended approach is to reattach the broken tooth fragment, if it is possible. [4] Following reattachment, smoothing of the edges is undertaken. [ 4 ] [ 1 ] Depending on the extent of the fractured portion, a choice is made between a glass ionomer or permanent restoration, such as composite resin ...
If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm. If the tooth can be found, pick it up by the crown (the white part). Avoid touching the root part.
In addition, broken, missing or malaligned teeth can often be appreciated on a panoramic image which is frequently lost in plain films. Medial/lateral displacement of the fracture segments and especially the condyle are difficult to gauge so the view is sometimes augmented with plain film radiography or computed tomography for more complex ...
When the lower jaw is pushed anteriorly as far as possible with some teeth in contact, it is said to be maximum protrusion. In Posselt's border movement diagram, maximum protrusion is the most anterior based on the sagittal view. Condyles are in the most anterior position and determined partly by stylomandibular ligaments. [8]
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
Failure to re-plant the avulsed tooth within the first 40 minutes after the injury may result in a less favorable prognosis for the tooth. [15] If the tooth cannot be immediately replaced in its socket, follow the directions for any knocked-out (avulsed) teeth kit, or place it in cold milk or saliva and take it to an emergency room or a dentist.
A tooth is composed of an outer shell of calcified hard tissues (from hardest to softest: enamel, dentin, and cementum), and an inner soft tissue core (the pulp system), which contains nerves and blood vessels. The visible parts of the teeth in the mouth – the crowns (covered by enamel) – are anchored into the bone by the roots (covered by ...
