چکیده
BACKGROUND indirect anthropometrical measurements of the height of the upper lip and length of the philtrum. AIM to describe the measurements of the height of the upper lip and length of the philtrum, extracted from video x-rays, in children with mixed dentition, relating these measurements to facial typology--medium and long-, to occlusion--Angle's class I and II--and to the rest position of the lips--with and without lip seal. METHOD verification of 123 x-rays, in lateral norm, of children with ages between 7:7 and 11:10 years, 56 male and 67 female, extracted from archives of orthodontical documentation prior to treatment. RESULTS the T-Student test, with a significance level of 5%, was used for the statistical analyses and the obtained results were: for the height of the upper lip no statistical difference was found considering the variables of face typology, occlusion and gender; there was no statistical difference for the measurements of the philtrum considering the variables of face typology and occlusion, but a statistically significant difference was found for the variable gender: a statistically significant difference was found for the height of the upper lip and length of the philtrum considering the variable rest position of the lips--with and without lip seal--being this a determinant factor for the measurements. This finding suggests that a direction of structural modifications may exist. CONCLUSION the mean value for the height of the upper lip was established at 21mm; the mean value for the length of the philtrum was established at 12mm. It is important to consider the rest posture of the lips, during assessment and therapy, when taking the measurements of the height of the upper lip and length of the philtrum.

Youth swimming performance may be influenced by anthropometric, physiology, and biomechanical factors. The purpose of this study was to analyze the relationships between 50-m front-crawl swimming performance and relevant anthropometrical (body height, body mass, body mass index, arm span, shoulders width, thigh, leg and upper arm lengths), muscle architectural (muscle thickness, pennation ...
