Abstract

Dens invaginatus is a malformation of tooth resulting from an infolding of the enamel epithelium during tooth development. This malformation shows a broad spectrum of morphologic variations. This invagination frequently allows the entry of irritants and microorganism, which usually lead to necrosis of the adjacent pulp tissue and then to periapical or periodontal abscess. Root canal treatment of such tooth is often difficult because of the un usual form and complicated pulpal space. This article reports 2 cases of dens invaginatus in maxillary lateral incisors. The first case was successfully treated with Ca(OH)₂. In the second case, involved tooth was extracted and this extracted tooth was observed using the micro-computed tomography.

Key Words: Dens invaginatus, Tooth malformation, Micro-computed tomography
