Apexiication without periodic changes of intracanal medicament and mtA apical plug: 5-year follow-up

Objective: The objective of this report was to present a case of apexification in traumatized teeth treated with two different therapies for immature teeth. Methods: An 11-year-old male patient was referred to the Dental Trauma Service of the College of Dentistry — Piracicaba (UNICAMP), with enamel dentin fracture in the maxillary central incisors associated with subluxation caused by a bicycle fall 3 years before. The radiographic examination revealed immature teeth. After necrotic pulp had been diagnosed, the treatment plan comprised apexification with intracanal medicament at the right central incisor and MTA apical plug in the left central incisor. The intracanal medicament protocol was performed with an obturation paste composed of calcium hydroxide, 2% chlorhexidine gel and zinc oxide without periodic changes. The MTA plug sealed the apical third of the root canal while the middle and cervical thirds were sealed with coltosol. Results: After an 8-month follow-up, apical closure of both teeth could be observed, without dissolution of intracanal dressing. After a 5-year follow-up, the teeth did not present symptomatology and the periapical lesions were repaired. Conclusion: Based on the results of this study it is reasonable to conclude that both apexification therapies may be concluded within a few sessions and may provide clinical success and comfort to the patient.
