This review article describes the methods and clinical recommendations for reinforcing traumatized anterior immature teeth with pulp necrosis treated with mineral trioxide aggregate (MTA) apexification. Traumatic injury can cause pulp necrosis and incomplete root formation in immature teeth. MTA apexification is the treatment of choice for necrotic immature teeth, particularly during the middle or late stages of root development. MTA apexification has a high success rate; however, failures due to cervical or root fractures occasionally occur...

Purpose: The purpose of this study was to present an evidence-based guideline for primary teeth with deep caries or trauma requiring vital pulp therapies (VPT). Methods: A systematic review/meta-analysis on vital primary teeth resulting from trauma or caries was conducted using GRADE to assess the certainty of evidence for clinical recommendations. A decision tree was provided for choosing VPTs. Results: No articles on trauma VPT were found. For VPT in primary teeth with deep caries, indirect pulp treatment (IPT) or pulpotomy using the calcium silicate cement (mineral trioxide aggregate [MTA] or Biodentine® ) show increased success over using direct pulp capping (DPC) and other pulpotomies...

BACKGROUND: Periapical surgery has been suggested as a treatment option for teeth with periapical lesions when those lesions continue despite receiving root canal therapy. Since sealing the apical region is the operation's primary goal, the choice of the root-end filling material affects how the surgery turns out. The retrofilling materials Zinc Oxide Eugenol (ZOE) and Mineral trioxide aggregate (MTA) are both known to have antibacterial characteristics. The purpose of this study is to determine how MTA affects as a Modulator of Periapical Tissue Healing through histological examination in Rat Molar...
