[0002] A cracked tooth refers to a non-physiological fine crack that occurs on the surface of the tooth crown and is often difficult to detect. The pathogenesis of a cracked tooth includes both internal and external factors. The clinical manifestations of a cracked tooth vary at different stages. For example, if the early crack is confined to the enamel, the patient may have no obvious symptoms; subsequently, the crack may extend to the dentin and cause excitation pain; if the crack involves the pulp, it may cause symptoms such as spontaneous pain; and eventually may lead to tooth fracture. Cracks mostly occur in maxillary molars, followed by mandibular molars and maxillary premolars. Cracked teeth are more common in clinical practice, but due to their hidden nature, diagnosis is more difficult, so clinicians need to pay enough attention and attention.
