Nonsurgical Endodontic Management of Dens Invaginatus Type IIIb - A Case Report
Melo-Ferraz, Antonio / Moreira, Telma / Azevedo, Adelia / Ferreira, Sonia / Miller, Paulo Cruz
Male patient, aged 20, was referred to the post-grad Endodontic clinic after an acute apical abscess episode associated to a complex internal tooth anatomy. Dental pulp tests performed on the maxillary right canine (13) were negative, and the presence of a sinus tract at the time of the appointment was noted. A diagnosis of total pulp necrosis and chronic apical abscess was made, with indication for non-surgical root canal treatment (NSRCT). Radiographic examination revealed a dens-in-dent (Dens Invaginatus DI) type IIIb (Oehlers classification) with presence of periapical radiolucency. CBCT was requested to aid treatment planning. The access cavity was carried out under rubber dam isolation using a round diamond bur in a high-speed hand-piece and refined using Start-X® (Dentsply-Sirona) ultra-sonic tips. Canal scouting and working-length determination was carried out using hand K10 files and an apex locator. The canals were instrumented using the WaveOne Gold® (Dentsply-Sirona) system and irrigated using NaOCl 5.25% and Citric Acid 10%, both activated using the sonic device EDDY® (VDW). Obturation was carried out using continuous wave and thermo-compaction of gutta-percha with resin cement 2Seal® (VDW) followed by a coronal seal with glass ionomer cement. The access cavity was restored using composite resin. A dental operating microscope was used for the whole procedure.
