Clinico-Radiological Perspectives of Pycnodysostosis - A Rare Case Series

Pycnodysostosis is an inherited autosomal recessive disorder characterized by dysplasia of the skeletal system. It occurs in any human races with no disparity in gender or age predilection. The disease is diagnosed at a young age owing to the frequent fragile bone fractures. Craniofacial and dental manifestations may overlap with those of other craniofacial dysostosis; therefore, precise knowledge is essential in differential diagnosis as it may affect the treatment outcome. Here, we report three cases with typical clinical and radiological features, among which one presented with osteomyelitis of the mandible.
