Periodontal healing of a horizontal root fracture: a case report with a two-year follow-up.
BACKGROUND
For traumatized teeth exhibiting crown-root fractures, there is a growing body of evidence that re-fastening the coronal part may result in successful treatment. However, data on the long-term impact of these bonding procedures on the periodontium are scarce. A case report of a young female patient presenting with an isogingivally- and horizontally-fractured lower incisor with a two-year follow-up is presented.


METHODS
The tooth fragment was reattached to the remaining root using an adhesive technique after flap elevation and endodontic therapy. No attempt was made to splint the coronal fragment to the neighboring teeth.


RESULTS
Despite the subgingival location of the bonding surface, uneventful periodontal healing was clinically monitored during the observation period. The coronal fragment was retained successfully for a period of more than two years.


CONCLUSIONS
Even for tooth fractures below the gingival margin, the combined approach of surgery and adhesive techniques can be used successfully to restore a severely traumatized tooth.
