Dens invaginatus is a developmental anomaly that arises from invagination of enamel organ into dental papilla during bell stage. The invagination begins at the crown and extends into root before its mineralization. Most common tooth affected by dens invaginatus is maxillary lateral incisors followed by maxillary central incisor, maxillary canine, mandibular lateral incisors, mandibular canine and mandibular central incisor. A classical case of Oehlers’ type IIIA dens invanigatus is presented
