Resumen de Relationship between internal root resorption and dens in dente

Ruth Pérez Alfayate, Montse Mercadé, Jorge Vera

• The aim is to report the treatment and follow-up of three lateral incisors with internal root resorption and dens in dente as a possible cause for their development, managed by root canal treatment and apical obturation with MTA or gutta-percha.

  This case report presents three clinical cases in which dens invaginatus type 2 is shown as a potential cause for the development of internal root resorption. Two cases were filled with a MTA apical plug technique and one with gutta-percha, and all were follow-up through time.

  The incidence of the association of internal root resorption with dens invaginatus may be underestimated and should be studied.
