This report demonstrates that root canal treatment of dens invaginatus in a maxillary lateral incisor with a sinus tract and large periradicular lesion can be successfully managed over a long period of time. The aim of this article is to show that contemporary technology, including a dental microscope and modern materials like mineral trioxide aggregate, are essential to secure a high survival of teeth, which have a difficult anatomy. The complex morphology of the root canal system and the invagination requires accurate intracoronal inspection, in order to find all delicate parts that need to be instrumented, disinfected and obturated. An 11-year-old girl with a type III dens invaginatus was referred to the Department of Operative Dentistry. A multiple-visit endodontic procedure was necessary to find, instrument and seal both the root canal and the invagination successfully. The presented case was treated by means of conventional non-surgical root canal treatment and apical placement of ProRoot MTA (Dentsply DeTrey, Konstanz, Germany). At 10-year follow-up the tooth was asymptomatic (no response to percussion or palpation) and complete periapical bone healing was observed radiographically. In the meantime the tooth was restored with a ceramic crown.
