The mesiodens, the most common type of supernumerary tooth, is found in the midline of the maxilla, between and generally palatal to the central incisors. Its prevalence in the permanent dentition ranges from 0.1 to 3.6% and in the primary dentition from 0.2 to 1.9%, (summarized in Sykaras, 1975), occurring more commonly in Asians (Zhu et al., 1996), including presumably Native Americans, and at least twice as often in males (e.g., Liu, 1995; Tay et al., 1984). Three orientations have been described: vertical (similar to normal teeth); inverted (crown oriented cranially); and horizontal or transverse. Vertical or inverted are both common (Asaumi et al., 2004; Liu, 1995; Rajab and Hamdan, 2002; Tay et al., 1984). The horizontal orientation is rare. Asaumi et al. (2004) found only 6% of mesiodens to be horizontal, similar to the rates of 6-8% and 5-6% for all horizontal supernumeraries reported by Rajab and Hamdan (2002) and Tay et al. (1984), respectively. The present report describes the first known incidence of an impacted horizontal conical mesiodens in a child’s skeleton, recovered during on-going investigations at Hank’s site (41RB109), an archeological site in the northern Texas panhandle.
