The most common traumatic dental injury is the uncomplicated crown fracture of the maxillary central incisor. Various reports have been written about reattachment of the fragment, and literature reviews have cited this technique as the best way of treating these injuries if the fragment is available and properly stored. The case presented here is of a child who sustained an uncomplicated crown fracture with the lost portion of the tooth embedded in his lower lip. This was successfully reattached to the tooth using an acid-etch and enamel-bonding resin technique.
