Sažetak
Dental anomalies in humans are rare developmental alterations involving the normal number, morphology, size, eruption, and position of one or more teeth in primary or permanent dentitions. To date, the etiology of these anomalies is still yet to be fully understood, since they are caused by interactions between genetic, epigenetic, and environmental factors. However, familiarity is considered to play an important role in their onset. In this paper, we report two new cases of dental anomalies recorded in two adult skeletal individuals from the Mesolithic graveyard UA 50 (Eastern Sudan, 5th millennium BCE). The mature male from Grave 3 shows bilateral supernumerary mandibular premolars. The two additional teeth erupted on the lingual side of the mandibula between the fourth premolars and the first molars. The young adult female from Grave 1 shows the retention of the deciduous mandibular right canine, the intra vitam loss of both mandibular central incisors, and the transmigration of the right mandibular canine with the impaction of the left one. Both mandibles were subject to gross morphological analysis and cone-beam computed tomography (CBCT) 3D volumetric measures. Evidence of dental anomalies in past populations is still scanty and, as far as we know, the reported cases are the oldest dental anomalies so far recorded in prehistoric Sudanese populations.
