A tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [37] A splint can either be flexible or rigid.
Other fractures of the body, are classified as open or closed. Because fractures that involve the teeth, by definition, communicate with the mouth this distinction is largely lost in mandible fractures. Condylar, ramus, and coronoid process fractures are generally closed whereas angle, body and parasymphsis fractures are generally open.
The term anterior teeth refers to incisors and canines, as opposed to premolars and molars, which are posterior teeth. [1] Apical The direction toward the root tip(s) or apex(es) of a tooth (the apices), as opposed to coronal, which refers to the direction toward the crown. It may also refer to something relating to the roots, such as apical ...
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
However, the Ancient Egyptians noted open fractures to have a poor prognosis, and fifth dynasty graves have been discovered containing people who had died from open fractures. [37] During the 19th century Crimean War, the use of plaster-of-paris for the stabilization of open and closed fractures was pioneered. It has been reported that the ...

[10]: 24 The term is falling into disfavor and has given way to the more generalized description of fractures and cracks of the tooth, which allows for the wide variations in signs, symptoms, and prognosis for traumatized teeth. A fracture of a tooth can involve the enamel, dentin, and/or pulp, and can be orientated horizontally or vertically.
A crack, fracture and the mobility of a tooth are all interrelated as the pain and symptoms experienced from a tooth that has been cracked are very similar to that of a tooth that has been fractured. [2] A tooth crack is defined as an incomplete fracture of enamel or dentine and therefore is not usually associated with noticeable mobility. [8]
