Aim: Characterize the permanent dentition
morphology of a group of Afrodescendants
of Istmina (Chocó, Colombia)
Materials y methods: This quantitative
cross-sectional study determined the frequency
and variability of 35 incisor, canine,
premolar and molar morphological features
of the Arizona State University Dental
Anthropology System in 100 self-described
individuals as Afrodescendants (50 Female
and 50 male), aged between 5 and 18 years.
Results: Significant frequencies of winging
(99%), double blade of the central incisors
(86%), convexity of the lips (41%), crest of
the shoulder (35%), and distal crest (39% to
45%) were identified (95% to 98%), central
ridge (82% and 80%), mesolingual groove
(79%), distolingual groove (81%), hippocampus
reduction (86%), Carabelli cusp )
And cusp 7 (64%). No sexual dimorphism
and bilateral asymmetry were found in the
MCDS studied.
Conclusions: The frequency and variability
of the MCDD included in the dendrogram
showed that the Isthmian group had a
typical dental morphology of the Afrodescendant
populations distributed on
the Colombian Pacific coast, which were
derived from groups of the West African
coast included in The dental complex of
Saharan Africa. Likewise, it was possible
to detect the influence of mestizo and indigenous
populations occupying the same
geopolitical space.
