| Popis: | The purpose of this study was to determine if there were differences in the angle of eminentia of two 20th century populations based on race, age, gender, and number of teeth and whether there was asymmetry of the angles of eminentia. The sample included dry skulls from the Hamann-Todd Osteological collection as follows: 80 African-Americans (AA, 53 males and 27 females) and 62 European-Americans (EA, 49 males and 13 females), ranging in age from 16-77 years. The lateral, central, and medial aspects of the right and left slopes of the articular eminence were measured in a parasagittal plane. Independent t-tests, paired t-tests, and Pearson correlation coefficients were computed. For the AA population, the right central, lateral, and medial angles of eminentia were steeper than the corresponding left angles (paired t-test, p0.05); for the AE males only the right lateral and medial angles were significantly steeper than the corresponding left angles (paired t-test, p0.05). There were no significant relationships between age or number of teeth and the angle of eminentia measurements, nor were there differences in angle of eminentia by gender. There were two differences by race: the EA males had steeper left central and left medial angles than the AA males (independent t-test, p0.05). The central angle of eminentia was consistently steeper than the medial angle (paired t-test, p0.01), and the lateral was generally steeper than the medial. |
