[Treatment of superior incisor gemination]

An 11 year old child presented to our department with an isolated abnormality of the left superior median incisor which was bigeminate. The existence of two distinct roots allowed the separation of 21 and 21 b with extraction of 21 b and preservation of 21, whose crown was reconstituted by means of a composite. There was a favourable outcome with conservation of the vitality of the tooth and no signs of ankylosis.
