Crown Fractures |
|
¨ Enamel fractures: selective grinding of the incisal edge/ acid-etch composite.
¨ Enamel and dentine fractures: coverage of exposed dentine should be bacteria-tight.
¨ Pulpal exposures can be treated successfully by formation of a calcific bridge if no inflammation was present prior to trauma and the vascular supply remains intact.
1. Pulp capping—small exposure, soon after injury 2. Pulpotomy—amputate 2mm below exposure 3. Pulpal extirpation—profound fractures of a mature tooth with associated periodontal ligament injuries
¨ Follow up required in order to diagnose pulpal complications ¨ Follow up schedule of 1/12, 2/12 and 1 year after injury ¨ Check for loss of pulpal sensibility, coronal discolouration and periapical radiolucency. |

Crown fractures represent a hazard to the pulp only if associated with a periodontal ligament injury. |
