Abstract

Known for its dental and clavicular abnormalities, cleidocranial dysplasia is a rare disorder of bones. The appearance of the patient often confirms the diagnosis: short stature; large head with pronounced frontal and parietal bossing; ocular hypertelorism; and broad base of the nose with a depressed nasal bridge. Gnathic and dental manifestations are distinctive and lead to the initial diagnosis. The patients often have a narrow, high-arched palate; prolonged retention of deciduous teeth, and delay or complete failure of eruption of permanent teeth; also present are supernumerary teeth. Two female patients, 25 and 21 years old, visited the stomatology clinic complaining about the presence of deciduous teeth. One presented with supernumeraries, an arched palate, and was characterized as brachycephalic. She reported delay in the closure of sutures. The other one had a prominent forehead. Panoramic radiographs were required. Both patients were diagnosed with cleidocranial dysplasia and referred for dental treatment.
