Relationship between biogeographical ancestry and facial characteristics and the presence of malocclusions
Keywords:
ancestría; color de la piel; características faciales; maloclusionesAbstract
Introduction: Facial morphology and predisposition to malocclusions are associated with biocultural variations and ancestral backgrounds that gave rise to modern populations. In Cuba, this association has been scarcely studied.
Objective: To determine the relationships established between biogeographical ancestry, skin pigmentation, malocclusions, and certain facial characteristics.
Methods: A descriptive, cross-sectional, exploratory study was conducted among Dentistry students at the University of Medical Sciences of Villa Clara during the period 2023–2024. Seventy individuals were selected through non-probability purposive sampling; foreigners and subjects with congenital facial malformations or those caused by accidents were excluded. Standardized anthropometric measurements were performed, and malocclusions were classified. Data processing was carried out using SPSS software, version 22.0 for Windows.
Results: Sixty percent of the subjects were white individuals of Europid ancestry; more than 75,0 % of them had an ovoid face, and another 50,0 % had a convex profile. On the other hand, 77,1 % of the detected malocclusions were Class II.
Conclusions: There is a correlation between biogeographical ancestry and skin pigmentation; as well as between the latter and face shape, profile type, proportionality of the middle and lower thirds, growth pattern, interpupillary diameter, vertical dimension, and nasal width.
