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.5 p.application/pdfeng(c) Medicina Oral SL, 2020DenticióCirurgia oralMalformacions de la bocaDentitionOral surgeryMouth abnormalitiesinfo:eu-repo/semantics/article7081342025-03-19info:eu-repo/semantics/openAccess32913579
