Bilateral Gemination



Gemination, anomalies


A 21-year-old male patient presented to the clinic with a main complaint of altered aesthetics of his front teeth. On clinical
examination the patient presented with peg-shaped maxillary lateral incisors as well as macrodontia of the maxillary central
incisors (Figure 1). Upon radiological examination, the microdont peg-shaped lateral incisors (12 and 22) were evident and
the 11 and 21 presented each as a single enlarged tooth with a bulbous root and bifid crown with a cavitated central groove
(Figure 2). The tooth count in the patient was normal, hence a diagnosis of bilateral gemination of the crowns of the maxillary
central incisors were made. The patient was referred to the restorative department for further treatment
