Report of Three Fused Primary Human Teeth in an Archaeological Material

Fusion of deciduous teeth can appear in several ways, usually involving two teeth but occasionally three. The frequency of this anomaly is reported to be low and few cases have been described in the scientific literature. Fused teeth in the archaeological record are rare because of the destructive taphonomic processes to which bones and teeth are subjected. Previous research in this field has only dealt with cases of two fused deciduous teeth. To our knowledge, there have been no reports of three fused teeth in the anthropological literature. The present paper presents a case of three fused primary teeth and a succedaneous supernumerary permanent tooth in a 5-year-old child discovered in a late medieval cemetery in northern Italy.
