Case Report. Use of Mineral Trioxide Aggregate in Permanent Incisors With Horizontal Root Fractures: A Five-Year Follow-Up

Basak Altinok, Betul Kargul

Incisors are the most frequently involved teeth to suffer dental trauma, with root fractures occurring in 3% of injuries due to dental trauma. Horizontal root fractures mostly affect upper central incisors, mainly in the middle third of the root. Nevertheless, apical and coronal third fractures are also sometimes reported. This case report presents the five-year follow- up of a 16-year-old male who had sustained trauma to his upper right central incisor (11) with a horizontal root fracture in the middle third of the root, and to the right lateral incisor (12) in its cervical third. The upper central incisor was treated with mineral trioxide aggregate (MTA) at the fracture line and the upper lateral incisor was filled with MTA and gutta-percha to achieve an apical seal. MTA allowed healing and prevented the occurrence of clinical symptoms. In conclusion, MTAappeared to be a valid option for the horizontal root fracture and had the added advantage of speed of completion of therapy.
