The nature and extent of jaw involvement in Gaucher disease: observations in a series of 28 patients.

A wide variety of osteoarticular pathoses plague the clinical course of many patients with Gaucher disease. Osseous lesions involving the jaws have been described, usually as isolated case reports. The purpose of this study was to ascertain the nature and extent of mandibulo-maxillofacial pathosis in 28 patients with documented Gaucher disease by means of panoramic radiography. Twenty-five of the 28 patients displayed radiographic evidence of jaw involvement. The most prevalent finding was gross widening of marrow spaces; frank radiolucencies, endosteal scalloping, cortical thinning, root resorption, and inferior displacement of the mandibular canal or effacement of its cortices were also seen. A previously unreported finding was delayed eruption of permanent teeth, which was seen in more than one half of the patients who were under 20 years of age. Osseous changes throughout the jaws may be more common than previously suspected and may alert the dentist to the presence of the disease.
