Os traumatismos dentários representam um problema de saúde pública devido à alta prevalência e impacto psicossocial, sendo muito frequentes em crianças podendo resultar em necrose pulpar e culminar na rizogênese incompleta de dentes permanentes. Nestes casos de traumatismos em dentes permanentes com rizogênese incompleta e necrose pulpar, o tratamento mais indicado pela literatura é a apicificação, sendo um tratamento complexo e longo. Considerando a importância deste tema, o objetivo deste trabalho é relatar o caso de um paciente com traumatismo dental e necrose pulpar, que acarretou a interrupção do desenvolvimento completo e adequado do ápice dentário, sendo necessária a intervenção por meio da técnica de apicificação e o acompanhamento a longo prazo. O caso trata-se de uma menina em que um traumatismo dentário acarretou fratura de um incisivo central superior com formação radicular incompleta, comprometendo tanto a estética quanto a vitalidade do dente. Foi realizado o tratamento endodôntico com apicificação e posteriormente ao plug apical de MTA. O dente foi restaurado definitivamente com resina composta e realizado acompanhamento do paciente. Nas consultas de acompanhamento houve ausência de sintomatologia dolorosa e satisfação da paciente com a aparência atual. Sendo assim, a apicificação apresenta-se como uma ótima alternativa para dentes com rizogênese incompleta e necrose pulpar, embora longo houve uma melhora estética e satisfação do paciente.


Dental trauma represents a public health problem due to its high prevalence and psychosocial impact, being very frequent in children and can result in pulp necrosis and culminate in incomplete root formation of permanent teeth. In these cases of trauma to permanent teeth with incomplete root formation and pulp necrosis, the most indicated treatment in the literature is apexification, which is a complex and long treatment. Considering the importance of this topic, the objective of this work is to report the case of a patient with dental trauma and pulp necrosis, which caused the interruption of the complete and adequate development of the dental apex, requiring intervention through the apexification technique and follow-up. long-term. The case is about a girl in which a dental trauma resulted in a fracture of a maxillary central incisor with incomplete root formation, compromising both the esthetics and the vitality of the tooth. Endodontic treatment was performed with apexification and then apical MTA plug. The tooth was definitively restored with composite resin and the patient was followed up. In the follow- up consultations, there was no painful symptomatology and the patient was satisfied with her current appearance. Thus, the apexification presents itself as a great alternative for teeth with incomplete root formation and pulp necrosis, although in the long run there was an aesthetic improvement and patient satisfaction.

Se trata de una niña en la que un traumatismo dental provocó la fractura de un incisivo central maxilar con formación radicular incompleta, comprometiendo tanto la estética como la vitalidad del diente. Se realizó tratamiento endodóntico con apexificación y posterior taponamiento apical con MTA. El diente fue restaurado definitivamente con resina compuesta y el paciente fue sometido a seguimiento. En las consultas de seguimiento, no había sintomatología dolorosa y la paciente estaba satisfecha con su aspecto actual. Así, la apexificación se presenta como una gran alternativa para dientes con formación radicular incompleta y necrosis pulpar, aunque a la larga se produjo una mejoría estética y satisfacción de la paciente.

Abstract Objective: To evaluate the sealing capacity and retention of apical barriers made with mineral trioxide aggregate (MTA) and Portland cement (PC). Material and Methods: Fifty-six bovine incisors were sectioned 8 mm above and 12 mm below the cement-enamel junction. The root canal was enlarged with a diamond drill to create a standard 2.5 mm diameter opening. Apical sheets of 5 mm thickness were placed using white MTA-Angelus or white PC. Fifteen samples of each material were exposed to human saliva in a dual chamber apparatus and casting was evaluated at 30 days. Samples without apical barriers and fully sealed samples were used as positive and negative controls (n = 3), respectively. Data were analyzed by Fisher's exact test (p<0.05) after 3 periods: 1 to 10 days (P1); days 11 to 20 (P2); and days 21 to 30 (P3). Then, three 1 mm thick sections were obtained at the apical level of other root samples of each material (n = 10) and the push-out test was performed Results: The leakage rates in P1, P2 and P3 were 60%, 73.3% and 100% for the MTA; and 73.3%, 86.7% and 100% for CP, with no significant difference between materials, regardless of the period analyzed. There were no significant differences between the bond strengths for both cements (p>0.05) Conclusion: Mineral trioxide aggregate and Portland cement apical barriers presented similar sealing ability and bond strength values.
