title: Syndrome of Hajdu-Cheney: three case reports of orofacial interest.
abstract: Hajdu-Cheney syndrome is a rare, probably autosomal dominant connective tissue disorder with a variable expressivity. It is characterized by an osteoporotic skeleton, acro-osteolysis, a proportionate short stature, and distinctive orofacial anomalies. The aim of this article is to focus on the orofacial manifestations in two sporadic cases and one familial case with Hajdu-Cheney syndrome. Several common dental and craniofacial features are described. In contrast to earlier proposed diagnostic features, these patients show persisting deciduous teeth, problematic tooth eruption, and tendency toward a Class III malocclusion.
