Introduction: The morphology of deciduous and permanent teeth’s characterization obtained from studying dental crown traits (dct), has been very useful to estimate micro-evolutionary processes of contemporary ethnic groups.   Objective: To describe –from dental anthropology’s perspective– the morphological configuration of the palatal and lingual surface of superior and inferior deciduous canines in a group of Misak native people.   Materials and method: A cross-sectional descriptive study of frequency, variability, sexual dimorphism, bilateral symmetry and correspondence of 8 dct of 60 study models (37 female and 23 male) obtained from a group of native Misak people from Silvia (Cauca, Colombia).   Results: High frequency of canine mesial crest was observed (73,3% superior and 70% inferior), palatal fossae (67,5%), lingual pits (59,2%) and central ridge (67,5% superior and 59,2% inferior); low shovel-shaped frequencies (17,5% superior and 10,8% inferior), dental tubercle (19,1% superior), and accessory distal crest (32,5% superior). Also, it was possible to observe practically no furrow interruption (6,7% superior and 3,3% inferior), dental tuber (0,0% inferior) and accessory distal crest (6,6% inferior). There was no sexual dimorphism, bilateral symmetry was also observed.   Conclusions: The palatal and lingual surface of superior and inferior deciduous canines configured a pattern of two marginal ridges (the mesial one resulted to be more evident than the distal one), a central ridge and two palatal (lingual) pits. This morphological pattern is characteristic in populations of different ethnic origins that occupy the same territory in southwestern Colombia.
