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.
