• Mineral trioxide aggregate (MTA) was assessed in pulpotomised primary molars.• The clinical and radiographic success rate of MTA was recorded at 24 months follow-up.• This clinical trial study showed the success of white MTA in primary molars. I N B R I E F RESEARCHPurpose The aim of this study was to compare the effect of white mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomised primary molars. Methods In this clinical trial study, 60 lower second primary molars of 46 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) and FC (control) groups by random numbered table. Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with an MTA paste in the experimental group. In the control group, FC was placed with a cotton pellet over the pulp stumps. The teeth of both groups were restored with stainless steel crowns. Children arrived for clinical and radiographic follow-up evaluation after 6, 12 and 24 months. Results The treated teeth in FC group (n = 18) were clinically and radiographically successful after 24 months. The radiographic follow-up evaluation revealed one failure (furcation involvement) in 18 molars treated with MTA after 24 months. The treated teeth in MTA group were clinically successful 24 months postoperatively. Pulp canal obliteration was observed in one of the teeth treated with MTA and four of the teeth treated with FC. Conclusion MTA could be used as a safe medicament for pulpotomy in cariously exposed primary molars and could be a substitute for FC.

“…Muchos estudios in vitro e in vivo han demostrado que el mta, por sus características, presenta buenas cualidades en cuanto a la prevención de filtración, biocompatibilidad, además de que no es reabsorbible, posee una buena resistencia a las fuerzas compresivas y capacidad de estimular la regeneración de tejidos como lo son la pulpa, además de los tejidos perirradiculares [10,16,17,18,23].…”

“…Este material provee un excelente capacidad de selle sobre la pulpa vital al no disolverse fácilmente cuando este se usa [9,10]. El material fue introducido en 1993 por Torabinejad, patentado en 1995 y aprobado para procedimientos endodónticos en 1998 [11][12][13].…”

“…Sin embargo, sus propiedades de biocompatibilidad hacen que este material tenga propiedades adicionales, como la formación de tejido duro similar al cemento, permite la adherencia osteoblástica y la regeneración ósea entre otras. El mta también es utilizado como alternativa en ciertas condiciones clínicas además de la terapia pulpar, como reparación de perforaciones, reabsorciones y cirugía apical, entre otras, lo que hace al material ser una buena elección [10,11,14,[16][17][18][19][20][21][22].…”

Uno de los principales objetivos de la terapia endodóntica es realizar una limpieza químico-mecánica del sistema de conductos radiculares con la eliminación completa del tejido pulpar en dientes que tienen su desarrollo completo y han sufrido algún tipo de patología pulpar; sin embargo, hay casos en los que el objetivo es mantener parte de ese tejido para promover el desarrollo de las raí-ces en dientes que han sufrido algún tipo de afección y no han terminado aún su formación radicular. Para estos casos, la apexogénesis es un tratamiento que permite inducir el cierre apical de dientes con formación radicular incompleta. Este reporte de caso describe el tratamiento de una niña de 7 años de edad que consulta al Servicio de Urgencias de la Universidad Cooperativa de Colombia, sede Medellín, relatando dolor ocasional en la zona mandibular izquierda. Al examen clínico el diente afectado fue examinado clínica y radiográficamente; en el primer molar inferior permanente izquierdo se observó una caries extensa y ápices inmaduros. Se le realizó un procedimiento conservador de apexogénesis con mta y seguimiento a un año evidenciando el cierre apical de sus raíces totalmente asintomático.Palabras clave: apexogénesis, ápice radicular inmaduro, dolor, hidróxido de calcio, mta, pulpotomía. Apexogenesis of a First Permanent Mandibular Molar with mtaAbstract. One of the main goals of endodontic therapy is to chemically and mechanically clean the root canal system with the complete removal of the pulp tissue in teeth that are fully grown and have suffered some kind of pulp pathology. However, there are cases in which the goal is to keep some of that tissue to promote root development in teeth that have undergone some type of pathology and have not yet finished their root formation. For these cases, the apexogenesis is a treatment that can induce apical closure of teeth with incomplete root formation. This case report describes treatment of a 7 year old girl that consulted at the Department of Dental Emergencies of the Universidad Cooperativa de Colombia with an occasional pain on her left lower jaw. The tooth responsible was examined clinically and through x-rays. On clinical examination, the first permanent left mandibular molar had extensive caries and immature apices. Radiographic examination revealed an immature root. We performed conservative treatment (apexogenesis) and then a 1 year follow up that evidenced apical closure and the disappearance of the symptoms.Keywords: apexogenesis, immature tooth root apex, pain, calcium hydroxide, mta, pulpotomy.

RESUMODiversos medicamentos vêm sendo testados e utilizados na terapia pulpar conservadora de dentes decíduos, no entanto, o formocresol continua sendo o material de escolha nas pulpotomias, mesmo não atendendo às exigências de biocompatibilidade e promovendo a fixação do tecido pulpar vital e não o seu reparo. Com o surgimento do Agregado Trióxido Mineral (MTA) como um material com propriedades físico-químicas que promovem o reparo tecidual, aliados a outras propriedades importantes, tais como a ação antimicrobiana e a biocompatibilidade aos tecidos pulpares surgiu uma nova alternativa de material na Odontologia. O objetivo deste estudo foi relatar o desempenho do MTA em uma pulpotomia em molar decíduo e seu acompanhamento por um período de 1 ano. Foi realizada a pulpotomia com o uso do MTA no dente 85 de um paciente de 5 anos de idade cujos resultados obtidos foram bastante favoráveis, demonstrando sucesso clínico e radiográfico no período avaliado. Apesar do pouco tempo de acompanhamento do dente decíduo tratado, acredita-se que o MTA possa ter um grande potencial biológico e futuramente podendo transformar-se em uma opção de material para ser utilizado como rotina nas pulpotomias de dentes decíduos.Termos de indexação: Cimentos dentários. Pulpotomia. Dente decíduo.
