Pyknodisostosis (PKND):
• is a rare sclerosing bone disorder (characterized by the
creation of abnormally dense and overgrownbones. The abnormal bone
formation in sclerosing bone dysplasias is caused by a defect in the
replacement of old bone with new bone)
•. characterized with generalized diffuse osteosclerosis (elevation

of bone density) .
• is an esqueletal autossomal recessive disorder.
• Patients with PKND usually have normal intelligence, sexual
development and life span1.
•Other clinical features are skulldeformities, an obtuse gonial
angle, hypoplastic paranasal sinus, shortened terminal
phalanges and a history of multiple fractures of the members and
clavicles2.
•Oral manifestations include anterior crossbite, increase incidence
of dental caries, hipoplastic maxilla2. .
•Radiographic findings include bone density increase, persistent
fontalelles and failure of closure of the cranial sutures1,2.
•Thissyndrome has been seen in many races and nationalities,
including black, Arab and caucasians3.
