Morphological Integration of Soft-Tissue Facial Morphology in Down Syndrome and Siblings
trisomy 21 craniofacial morphology
2014/11/6
Down syndrome (DS), resulting from trisomy of chromosome 21, is the most common live-born human aneuploidy. The phenotypic expression of trisomy 21 produces variable, though characteristic, facial mor...
Evaluation of Correlation between Width and Morphology of Mandibular Inferior Cortex in Digital Panoramic Radiography and Postmenopausal Osteoporosis
Osteoporosis Postmenopause Bone mineral density Mandible
2015/9/22
Background: In osteoporotic patients, inferior mandibular cortex undergoes resorption which its manifestations can be detected on dental panoramic radiographs as a simple and available method. The aim...
