    Abstract:
    OBJECTIVES: To investigate the radiographic findings of mucopolysaccharidoses (MPS) on panoramic radiographs in a series of 16 patients. STUDY DESIGN: This retrospective cross-sectional study included panoramic radiographs of 16 patients with cytogenetically diagnosed MPS. Two blinded, previously calibrated observers evaluate the presence or absence of the following features: type of dentition; stage of dental age in comparison with chronologic age; delayed exfoliation of deciduous teeth; supernumerary teeth; teeth impaction; enlarged, cyst-like dental crypt; hypercementosis; taurodontism; generalized enamel hypoplasia; enlargement of the bone marrow spaces; thinning of cortical bone; unusual morphology of condyles; and flattening of the condylar head. RESULTS: The final sample was composed of 8 MPS IV, 7 MPS VI, and 1 MPS I cases. All patients presented unusual morphology of condyles. Cyst-like dental crypt (75%), taurodontism, and teeth impaction (68.75% each) were also overall common findings. Generalized enamel hypoplasia was exclusively identified in patients with MPS IV (75% of those patients). CONCLUSIONS: Radiographic features of oral and maxillofacial manifestations in patients with MPS frequently encountered by dentists may help recognize the disorder. However, because of sample size limitations, it was not possible to infer any statistical relationship between the radiographic features and the types of MPS.
