Abstract
In addition to caries, dental trauma is one of the most common causes of damage to permanent teeth and pulp. Pulp necrosis or damage to Hertwig’s epithelial root sheath (HERS) leads to arrested tooth root development in immature teeth. Pulp necrosis can be treated by revitalization, a biology-based treatment alternative to apexification. Induction of a blood clot inside the root canal can lead to healing of periapical lesions and increased root length and thickness. Traumatic impact as the cause of pulp necrosis may affect the treatment outcome negatively, depending on the severity of damage to HERS. Revitalization procedures in four teeth with pulp necrosis following dental trauma were performed using a standardized treatment protocol. Three teeth were dislocated, the fourth tooth was avulsed. Each patient exhibited at least two clinical signs of pulp necrosis as well as radiographic evidence of apical periodontitis. X-rays were taken using individualized film holders (IFH) to reliably assess the treatment outcome. Revitalization treatment was performed without instrumentation of the canal walls, but disinfection with sodium hypochlorite and intracanal dressing with triple antibiotic paste (TAP) for three weeks. Provocation of bleeding was induced in a second visit, the blood clot was covered with collagen followed by calcium silicate cement, and teeth were sealed with resin composite. Clinical and radiographic follow-ups were performed after 1, 3, 6 and 12 months. An increase of root length and thickness was evident in the three teeth with dislocation injuries. In one case, formation of mineralized tissue below the calcium silicate cement was observed. The tooth which had been avulsed and replanted showed resorption of the apical root area. The observations made in this study support the assumption that a separation of HERS and the cells that form pulp and dentin during tooth root development may negatively affect the outcome after a standardized revitalization procedure. The consistent implementation of standardized treatment protocols and the use of IFH are helpful receiving a reliable treatment outcome.
