Compound Odontome Causing Agenesis of Mandibular Canine

A 20-year-old female patient reported with a complaint of crowding of teeth with food lodgment. Panoramic radiograph [Figure 1a] revealed small multiple radiopaque structures between the roots of the mandibular right lateral incisor and first premolar having similar density to the adjacent roots. The treatment was started with the surgical excision [Figure 1b and c] of the radiopaque masses. Histopathology [Figure 2a and b] revealed irregularly deposited mature tubular dentin encasing a small collection of pulpal tissue, cementum, and irregular spaces occupied by enamel indicating compound odontome. It tends to occur between the teeth in the form of multiple small teeth-like structures. Asymptomatic and found incidentally, the standard management of an odontome is its complete removal to avoid any recurrence. In case of recurrence other lesions of odontogenic origin like calcifying odontogenic cyst and ameloblastic fibro-odontoma should be ruled out. Odontome can result in the delayed exfoliation of deciduous tooth and eruption of permanent successors; interestingly the presented case showed agenesis of the mandibular canine.Figure 1: (a) Panoramic radiograph showing multiple small malformed teeth-like structures between the roots of the mandibular lateral incisor and 1st premolar.
