Enamel-dentine fracture is a complete fracture of the tooth enamel and dentine without the exposure of the pulp. Pulp sensibility testing is recommended to confirm pulpal health. Treatment depends on how close the fracture is in relation to the pulp. If a tooth fragment is available, it can be bonded to the tooth.
Enamel fractures can vary in severity, ranging from minor cosmetic issues to more significant structural problems. [1] An enamel fracture typically doesn't cause any noticeable symptoms such as tenderness or an increase in mobility. However, if sensitivity and mobility are present, it may indicate an enamel-dentine fracture or a root fracture. [1]
The primary cause of enamel wear in the grooves is the direct mechanical forces applied during chewing, such as vertical pressure and lateral forces as teeth grind or shear food. Particularly in areas where food is more frequently trapped or where contact is poor, the continuous friction between the food and the tooth surface causes abrasion ...
Trauma to primary teeth occurs most commonly at the age of two to three years, during the development of motor coordination. [7] When primary teeth are injured, the resulting treatment prioritises the safety of the adult tooth, [7] and should avoid any risk of damaging the permanent successors. [8]
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 ...
[7] Multiple indices have been developed in order to assess and record the degree of tooth wear, the earliest was that by Paul Broca. [8] In 1984, Smith and Knight developed the tooth wear index (TWI) where four visible surfaces (buccal, cervical, lingual, occlusal-incisal) of all teeth present are scored for wear, regardless of the cause.

Management of injured primary teeth differs from management of permanent teeth; avulsed primary tooth should not be re-planted (to avoid damage to the permanent dental crypt). [16] Although dentists advise that the best treatment for an avulsed tooth is immediate replantation, [17] [18] for a variety of reasons this can be difficult for the ...
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]
