Treatment of horizontal root fractures using MTA as apical plug: report of 3 cases.

Root fractures are rare occurrences through all dental injuries. They comprise only 0.5% to 7.0% of traumas affecting the permanent teeth. Generally the cervical and middle thirds of the roots are affected. The healing of these lesions depends on the health of the pulp, dentine, cementum, and alveolar bone. These case reports describe the management and 2-year follow-up of 3 maxillary central incisors with horizontal root fractures treated with mineral trioxide aggregate (MTA) as apical plug.
