Fractured teeth can be divided into crown fracture, root fracture, etc. For crown fracture without pulp exposure, composite resin can be used for bonding repair, while other cases usually require root canal treatment and then restorative treatment, as follows. 1. Crown fracture: if the crown fracture is not exposed to the pulp, after dentin desensitization, composite resin can be used to repair the crown; if the crown fracture is exposed to the pulp, pulp removal surgery is required, and then the crown defect can be repaired by using the nucleus pulposus crown. 2. Root fracture: If the root fracture is located in the apical or middle 1/3 of the root, first use the splint to reset and fix, if the pulp has necrosis symptoms, root canal treatment, if the root fracture is located in the cervical 1/3, and with the gingival sulcus traffic, gingival incision can be used to extend the root of the tooth relative to each other, and then the routine endodontic treatment, dental crown restoration. The same disease, the patient’s situation is different, the choice of treatment is different, it is recommended to go to the hospital in time for targeted treatment.
