Gemination and fusion are anomalies in size, shape and structure of teeth. Geminated teeth are typically disfigured in appearance due to irregularities of the enamel. Fused teeth can have separated pulpal space, one pulp chamber and two canals or take the form of a large bifid crown with one pulpal space. Fusion is differentiated from germination by a reduced number of teeth. An exception is in the unusual case in which the fusion is between a supernumerary tooth and normal tooth. Here we present a case of geminated primary maxillary later and a case of fusion of mandibular permanent central and
lateral.
