Dens invaginatus is a developmental dental anomaly that can predispose the tooth to pulp and periradicular disease. Management of this condition can be challenging because of anatomic and microbiologic issues. This case report describes the regenerative endodontic treatment using a strategic antimicrobial protocol for management of an immature maxillary lateral incisor with type-II dens invaginatus associated with apical periodontitis in a 13-year-old patient. The tooth presented with a complex anatomy and was associated with an active sinus tract. Because the true root canal was not negotiable in its coronal part due to the presence of the dens invaginatus, the closed end of the invagination (pseudocanal) was perforated to permit access to the apical segment of the true root canal for cleaning and disinfection. Both the invagination and the true canal were treated using an antimicrobial regimen based on chemomechanical preparation with sodium hypochlorite irrigation, supplementary disinfection with passive ultrasonic irrigation and interappointment calcium hydroxide medication. After 2 exchanges of calcium hydroxide medication, the sinus tract did not disappear, then the antimicrobial protocol was changed to include an antibiotic solution for irrigation and antibiotic paste for intracanal medication. After signs and symptoms disappeared, regenerative endodontic treatment was performed by inducing blood clot formation within the root canal. The coronal canal segment including the invagination was filled with Biodentine. Follow-up including cone-beam computed tomography examination showed complete healing of the apical periodontitis lesion and mineralized tissue formation at the apical portion of the true root canal.
