Comparative Effectiveness of Regenerative Endodontic Treatment Versus Apexification for Necrotic Immature Permanent Teeth With or Without Apical Periodontitis: An Umbrella Review.

Background/aim: The evidence related to the superiority of the recommended treatment protocols for necrotic immature permanent teeth is unclear. We aimed to compare the clinical, radiographic, and overall success rates of apexification and regenerative endodontic treatment (RET), assess the methodological quality, and assess the strength of evidence for outcomes.

Methods: A search was performed in PubMed, Scopus, LILACS, EMBASE, Web of Science, and the Cochrane Library.

Non-Surgical Endodontic Management of Large Periapical Lesions After Traumatic Dental Injuries.

Traumatic dental injuries of permanent teeth result in multiple immediate and long-term consequences depending upon the severity of trauma, age of the patient, the status of root maturity, and the emergency care provided. The healing responses may get disturbed due to severe damage, loss of vascularity of the supporting structures, and infections. As a result, the prohealing mediators and pathways are overpowered by the destructive stimuli often manifested by an increased osteoclastic activity.
