Aim: The purpose of these cases is to present the apexificationusing MTA and root canal treatment of maxillary andmandibular right central incisors which had an open apex.
Introduction: Mineral trioxide aggregate (MTA) has been used in dentistry especially, teeth with an open apex, such as an immature teeth. It was possible to optimize the treatment time of these cases by immediate placement of apical plug and the root canal filling.
Case Presentation: A 32 years old male patient referred toendodontic department for evaluation of tooth #11 and #31 with an open apex and periapical radiolucency. The patienthad no symptom. In clinical evaluation, non-complicate crownfracture was determined for tooth #11 and #31 and they had been traumatized when he was 8 years old. The root canaltreatments were done under local anesthesia and rubber-dam isolation. After shaping and irrigation, calcium hydroxide wasplaced as an intracanal medicament. After one week, calciumhydroxide was removed chemomechanically. MTA was mixedand carried into the canal with special MTA carrier and wascondensed to apical portion of root canal with pluggers. After24 hours, coronal parts of tooth were filled with gutta perchaand resin based sealers by using cold lateral condansationtechnique.
Discussion: Apexification is described as a method to induce a calcified barrier of an incomplete root in teeth with necrotic pulp. This barrier that used in this case MTA is mandatory to allow the compaction of the root filling material.
Conclusion & Clinical Relevance: The using of MTA forapical plug effectively treated teeth which had an apicallesions also with an open apex. The patient was recalled after2 years. Clinical examination showed that satisfactory healingand the radiography was showed that adequate periapicalresponse as well.
