Apicoformación de un incisivo lateral superior con MTA tras un traumatismo / MTA apexification of a maxillary lateral incisor after trauma

Un traumatismo dentario puede producir muchas complicaciones. Entre ellas podemos destacar la interrupción del desarrollo radicular o la afectación de los tejidos perirradiculares, pudiendo producirse una leve luxación o incluso una avulsión total del diente fuera de su alveolo. En este tipo de situaciones un buen diagnóstico y tratamiento precoz es importante para el pronóstico del caso. El incisivo lateral superior que vamos a presentar en este caso clínico presentaba un desarrollo incompleto del ápice. Frente a este tipo de situaciones la literatura presenta dos escenarios: realizar una apicoformación o bien una endodoncia regenerativa. Son muchos los factores que decantan el tratamiento por una u otra opción. En este caso realizamos una apicoformación con MTA en una sola sesión, pues las paredes del conducto parecen ser suficientemente gruesas y el diente es resistente. La apicoformación con MTA puede tener una alta tasa de éxito a largo plazo, debido a las propiedades de biocompatibilidad y sellado de este material, mientras consigamos desinfectar con irrigación el sistema de conductos. En la evolución del caso, la paciente se encontraba asintómatica y con signos de salud periapical

Dental trauma can cause many complications. Among them we can highlight the interruption of the radicular development or the affectation of the periradicular tissues, being able to produce a slight dislocation or even a total avulsion of the tooth out of its alveolus. In this type of situations a good diagnosis and early treatment is important for the prognosis of the case. The upper lateral incisor that we are going to present in this clinical case presented an incomplete development of the apex. Faced with this type of situation, the literature presents two situations: apexification or a regenerative procedure. There are many factors that decide the treatment by one or another option. In this case, we performed apexification with MTA in a single visit, since the walls of the canal appear to be thick enough and the tooth is resistant to fracture. Apexification with MTA can have a high rate of success in the long term, due to the properties of biocompatibility and sealing, while we manage to disinfect with irrigation the root canal system. In the follow-up, the patient was asymptomatic and with signs of periapical health

Tissue engineering in endodontics: root canal revascularization.

Root canal revascularization attempts to make necrotic tooth alive by the use of certain simple clinical protocols. Earlier apexification was the treatment of choice for treating and preserving immature permanent teeth that have lost pulp vitality. This procedure promoted the formation of apical barrier to seal the root canal of immature teeth and nonvital filling materials contained within root canal space. However with the success of root canal revascularization to regenerate the pulp dentin complex of necrotic immature tooth has made us to rethink if apexification is at the beginning of its end. The objective of this review is to discuss the new concepts of tissue engineering in endodontics and the clinical steps of root canal revascularization.
