| The objective of this study was to describe transversal dimensions of the dental arches, bite force and facial index in three ethnic groups representative of Colombia. The sample size included 197 adolescents, 12 to 14 year old, 33% mestizo, 35% of African ancestry and 32% Amazon Indian; 50.3% male and 49.7% female. The comparative analysis to determine differences between ethnic groups was made by the Kruskal Wallis test and then the Principal Component Analysis was used to establish the pattern of measurements identifying ethnic characteristics. All measurements showed statistically significant differences among ethnic groups except facial height (p=0.157). It was evidenced that Amazon indian have a higher bite force (p <0.05) than the other twoethnic... |

| The purpose of this study was to compare dental arch transversal and anteroposterior dimensions in three ethnic groups from Colombia. A digital caliper was used to take 16 transversal and two sagittal measurements, 9 for the upper jaw and 9 for the lower jaw. The sagittal measure determining arch length was drawn from a mesial line traced from first right permanent molar to first left permanent molar, and a perpendicular line from the point of contact between central incisive teeth, both for the upper and lower jaw. The dimensions of upper dental arch in the three ethnic groups showed differences in intercanine distance, as well as between premolar and between molar teeth. The same differences were found for lower dental arches. The populations evaluated... |
