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.
