It differentiates tooth fractures based on the extent of damage to tooth surfaces involved. This classification system is used to determine the severity of tooth fractures and to decide the treatment plan accordingly. (Diangelis & Bakland, 1998) Class I – Simple fracture of crown involving only enamel with little or no dentine involvement.
These fractures are often characterised by irregular breaks on the biting surface of the tooth, in contrast to the smoother surfaces associated with typical tooth degradation. [1] 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 ...
Enamel infractions are microcracks seen within the dental enamel of a tooth. [1] They are commonly the result of dental trauma to the brittle enamel, which remains adherent to the underlying dentine. They can be seen more clearly when transillumination is used. Enamel infractions are found more often in older teeth, as the accumulated trauma is
A crack in enamel with no loss of tooth structure Tooth is not tender No abnormalities Generally no treatment needed Discolouration of prominent cracks can be prevented by etching and sealing with resin No follow-up required 2) Enamel fracture Fracture involving enamel only Tooth not tender with normal mobility and pulpal response Loss of enamel
Another consideration is unsupported tooth structure. When preparing the tooth to receive a restoration, unsupported enamel is removed to allow for a more predictable restoration. While enamel is the hardest substance in the human body, it is particularly brittle, and unsupported enamel fractures easily.
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 ...
Endodontically treated teeth, especially those with little sound tooth tissue, are prone to fractures. The successful clinical outcome for these teeth relies not only on adequate root canal treatment, but also on the type of restorative treatment used, including the use of a post and core system and the type of extra-coronal restoration selected.
It has been proposed that the DEJ is crucial in preventing the progression of cracks from enamel to dentin and averting additional severe tooth fractures The dentino-enamel junction (DEJ) is an intricate biomechanical interface that forms the boundary between the highly mineralised enamel and the collagen-rich dentin.
