Relationship between internal root resorption and dens in dente. Journal of Clinical and Experimental Dentistry, 12(8), e800–e804. https://doi.org/10.4317/jced.569441989-5488http://hdl.handle.net/11268/10433Background: 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. Case description: 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. Practical implications: The incidence of the association of internal root resorption with dens invaginatus may be underestimated and should be studied.engjournal article10.4317/jced.56944open accessOdontologíaTecnología médicaCirugía
