Repair and restoration of a fractured, pulpally involved anterior tooth: report of case.

An 8-year-old boy was hit on the maxillary central incisor with a rock, resulting in a diagonal fracture and exposure of the pulp. After endodontic treatment, the fragment was joined to the tooth and the tooth restored using pins, a cold-curing composite, and an ultraviolet-light-activated material. This is a useful technique in cases were preparation of a fractured tooth is impossible or undesirable.
