“…This publication outlines 36 traits of the dentition as well as rocker jaw, and mandibular and palatine tori. This original work is based on a rich literature defining morphological variation of the teeth (e.g., Dahlberg ,1956;Hanihara ,1961;Harris and Bailit, 1980;Hrdlička ,1921;Morris, 1970;Morris et al, 1978;Scott, 1977;Scott, 1980;Tomes, 1914;Turner ,1970;Turner, 1971). However, since its publication, there have only been a handful of additional traits defined, including the canine mesial ridge (Irish and Morris, 1996), maxillary premolar accessory ridges (Burnett et al, 2010), deciduous morphological variants (Sciulli, 1998), and molar crenulations (Pilloud et al, 2017).…”
