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]
Fracture occurs due to the forces exerted on the dental unit. The enamel is splintering: [12] [13] [14] after an unfortunate fall, bump or contusion of the jaw; due to excessive chewing, eating too hard food, and chewing nuts and seeds; grinding of teeth and a bad habit of chewing on things, such as pencils, pens, etc.; due to stresses caused ...
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]
It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction (CEJ), undergoes large amounts of stress, causing micro fractures and tooth tissue loss. Abfraction appears to be a modern condition, with examples of non-carious cervical ...
Fractures (dental trauma) can occur anywhere on the tooth or to the surrounding bone, depending on the site and extent of the fracture the treatment options will vary. Dental restoration falling out or fracturing can also be considered a dental emergency as these can impact function in regards to aesthetics, eating and pronunciation and as such ...
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.
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.
However, they have been noted to be an important potential source of enamel fractures that arise after extended use or overloading. [8] It appears that, although enamel easily starts to form the fracture defects of enamel tufts, they then enable enamel to resist the further progress of these fractures, ultimately preventing mechanical failure.
