Mineral Trioxide Aggregate (MTA) As a Pulpotomy Agent in Developing Permanent Teeth: A Case Report

Introduction: Traumatic injuries or caries to developing permanent teeth may prevent the integrity of root maturation and finally result in pulp necrosis, vital pulp therapy (VPT) is a suitable treatment for these teeth. This article describes a successful apexogenesis report of a nine year old boy with impact trauma to the mandibular left first molar which caused complicated crown fracture, pulp exposure and thereupon spontaneous pain. Methods: Cervical pulpotomy was performed and the remaining pulp was capped with mineral trioxide aggregate (MTA). Afterwards the crown was restored using a stainless steel crown, the patient was followed up using radiographic images and clinical examinations 6 and 12 months after the treatment. Findings: The follow up documents indicated that the tooth maturation was completed, the apex was developed and a calcified barrier was formed right above the remaining vital pulp and no other endodontic treatments were needed. Conclusion: Regarding to the excellent healing potential of the immature vital pulp and using MTA as medicated filling matter, clinical and radiographic documents represent MTA as a successful pulpotomy agent in immature permanent teeth.
