CRANIOFACIAL ASPECTS IN TURNER SINDROME

Romanian Journal of Oral Rehabilitation, 2023
Our study shows craniofacial morphological abnormalities in Turner syndrome by analyzing linear and angular variables calculated on cephalometry. Craniofacial aberrant aspects are found in reduction of the posterior base of the skull, mandibular and ...

Landmark detection in 2D bioimages for geometric morphometrics: a multi-resolution tree-based approach [PDF]

, 2018
The detection of anatomical landmarks in bioimages is a necessary but tedious step for geometric morphometrics studies in many research domains. We propose variants of a multi-resolution tree-based approach to speed-up the detection of landmarks in ...

Cephalometrically analysis of the convexity angle [PDF]

Stomatološki glasnik Srbije, 2003
The convexity angle of facial bone structures ( N-A: A-Pg) expresses the sagittal protrusion of the maxillary part of the face compared to facial profile (the convex or concave face).The convexity angle is defined as the angle colligated by the lines N-A
