Apexification with a bioceramic reparative cement: a case report.

The aim of this case report is to describe the treatment of a maxillary right central incisor with pulpal necrosis and incomplete root formation. The 14-year-old patient had experienced trauma to both maxillary central incisors approximately 2 years earlier. Therapy consisted of apexification with a bioceramic reparative cement to form an apical plug. After the clinical and radiographic evaluations, the clinician opened the crown, performed the chemical-mechanical preparation, and placed calcium hydroxide-based medication. At the next appointment, 24 days later, the intracanal medication was removed through passive ultrasonic instrumentation; the canal was dried; and the bioceramic cement was inserted into the apical portion with the aid of a mineral trioxide aggregate holder. A sterile cotton ball, moistened with distilled water, was used to maneuver the material in the apical region, and a periapical radiograph was exposed to confirm the correct placement of the bioceramic reparative cement. The canal was filled with gutta percha cones and a bioceramic root canal sealer. All procedures were performed with the aid of microscopic magnification. Clinical and radiographic evaluations at the 18-month follow-up visit showed that the treated tooth was asymptomatic, suggesting that the bioceramic reparative cement is effective for apexification.

Similar Sealability Between Bioceramic Putty Ready-To-Use Repair Cement and White MTA

This study was designed to assess the ability to prevent glucose penetration of a bioceramic putty ready-to-use repair cement comparing to white mineral trioxide aggregate (WMTA). After root canal instrumentation, the apical 3 mm of maxillary incisors were resected and root-end cavities with depth of 3 mm were prepared with ultrasound and filled with the tested materials (15 roots per group). All roots were mounted in a double chamber system to assess glucose penetration using 15 psi pressure application. After 1 h, glucose concentrations in the lower chamber were measured following an enzymatic reaction. Four roots were used as controls. The Mann-Whitney test verified differences in glucose leakage between groups and the Tukey's test was used for multiple comparisons. Significance level was set at 5%. There was no significant difference in glucose leakage between iRoot BP Plus and White MTA groups. iRoot BP Plus had a similar ability to that of white MTA in preventing glucose leakage as a root-end filling material.

Este estudo foi desenhado para avaliar a capacidade de impedir a infiltração de glicose de um cimento reparador biocerâmico pronto para o uso, em comparação com o agregado trióxido mineral (MTA) branco. Após a instrumentação do canal radicular, os 3 mm apicais de incisivos superiores foram removidos, e retropreparos com 3 mm de profundidade foram realizados com ultra-som. As cavidades retrógradas foram preenchidas com os materiais testados (15 raízes por grupo). Todas as raízes foram montadas em um sistema de câmara dupla para avaliar a infiltração de glicose utilizando a aplicação de pressão de 15 psi. Depois de 1 h, concentrações de glicose na câmara inferior foram medidas seguida de uma reação enzimática. Quatro raízes foram usadas como controle. O teste de Mann-Whitney verificou diferenças na infiltração de glicose entre os grupos e o teste de Tukey realizou comparações múltiplas. A significância foi estabelecida em α= 5%. Não houve diferença significante entre a média e a mediana comparando-se os grupos do iRoot BP Plus e o MTA branco. iRoot BP Plus teve uma capacidade semelhante ao do MTA branco na prevenção da infiltração de glicose como material retroobturador.
