Enamel Fractures Enamel fractures (uncomplicated crown fracture) are limited to the enamel without exposing dentin or pulp. This type of fracture is usually located at a proximal angle or the incisal edge of the anterior region. (Olsburgh S, Jacoby T, Krejci I, 2002) Pulp sensibility tests and tooth mobility are usually normal.
An enamel fracture is when the outermost layer of the tooth is cracked, without damaging the inner layers including the dentine or pulp. This can happen from trauma such as a fall where the teeth are impacted by a hard object causing a chip to occur. Enamel fracture of tooth 11 on the incisal, biting, surface
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."
5) Crown-root fracture without pulp involvement Fracture involving enamel, dentine and cementum without pulp exposure Fracture extends below the gum margin Tender tooth with mobile crown fragment Fracture line extending down the root may not be visible Emergency: aim is to stabilise the loose fragment by splinting it to adjacent teeth
A fracture of a tooth can involve the enamel, dentin, and/or pulp, and can be orientated horizontally or vertically. [10]: 24–25 Fractured or cracked teeth can cause pain via several mechanisms, including dentin hypersensitivity, pulpitis (reversible or irreversible), or periodontal pain. Accordingly, there is no single test or combination of ...
In permanent teeth, the enamel rods near the cementoenamel junction (CEJ) tilt slightly toward the root of the tooth. Understanding enamel orientation is very important in restorative dentistry, because enamel unsupported by underlying dentin is prone to fracture. [10] The area around the enamel rod is known as interrod enamel.
They are occasionally called caveated enamel fractures. It is a micro-fracture or superficial break in a tooth's enamel layer that does not go into the dentin underneath. Usually, trauma—like a direct blow to the tooth—or stress from too much pressure—like bruxism—causes these infractions.
Complicated crown fracture: Involves the enamel, dentin and pulp: Loss of enamel and dentine with exposure of pulp, no TTP, normal mobility, pulp sensitive to touch: Pulp capping, partial pulpotomy or coronal pulpotomy if root of tooth still forming or root canal treatment. Review and monitor every 3 months and then yearly: Extract tooth or ...
