Regenerative Endodontic Procedures for Traumatized Immature Permanent Teeth with Severe External Root Resorption and Root Perforation

Regenerative Endodontic Treatment of Maxillary Incisors with a History of Severe Traumatic Injury

“…Disadvantages of MTA apical plugs include lack of root canal development and the possibility of further tooth fracture due to thin root walls. Another treatment option in these cases is regenerative endodontic procedures (REPs), with benefits such as the possibility of tooth root development and the possibility of increasing the thickness of the root canal walls [17,18]. For the same benefits, REP was used in this case report of necrotic immature teeth of a patient with history of dental trauma (complicated crown fracture and avulsion).…”

“…Recently, regenerative therapy has been used to manage the external root resorption of traumatized teeth. The resorption includes dentin and cementum, which is repaired by new cementum due to the presence of periodontal ligament stem cells, which, if properly signaled, can differentiate into cementoblast, not odontoblast, and repair the area with cementum [17].…”

“…Lu et al showed that REP might be used to manage traumatized immature permanent teeth with necrotic pulp and apical periodontitis associated with severe external root resorption and root perforation. It was also shown that the resorptive area could be arrested and subsequently be repaired with hard tissue [17]. Dastpak et al performed regenerative endodontic procedures for necrotic immature upper central incisor with external root resorption and chronic apical periodontitis in a patient with history of trauma.…”
