Abstract

Dens invaginatus is a dental anomaly that occurs during tooth development before mineralization phase, due to an infolding of the outer surface into the interior of teeth. The maxillary lateral incisors are the most frequently involved teeth. Using 3-dimensional imaging would help the dentist in making definitive diagnosis and performing the treatment.
This paper illustrates the root canal treatment of Oehlers’ type II dens invaginatus in maxillary left lateral incisors. A 48 –year-old male patient was examined at the dental department, Queen Alia Military Hospital. After history taking and proper clinical and radiographic examination his various maxillary left lateral incisor appeared to have dens invaginatus. Root canal treatment was initiated. Two canals, one of which represented the invagination, were instrumented, irrigated, and then obturated with a lateral condensation technique.
