Abstract
OBJECTIVE: The aim of this study was to correlate the clinical, demographic, and radiographic aspects of 82 cases of florid osseous dysplasia (FOD) from four countries assessed by five reviewers. STUDY DESIGN: Retrospective data of patients diagnosed with FOD were obtained from archives of five institutes and analyzed according to clinical and radiographic criteria. RESULTS: A total of 82 cases of FOD were included in the study. In the majority (77.5%) of FOD cases, black women were affected. The disease mainly affected the mandible (100%), and the stage of the lesion was directly correlated with the age (P < .05). The rates of convergence showed confluence of assessment in the mandible (posterior), and the highest rate of divergence between the reviewers was in assessing involvement in the maxilla. There were no differences among the characteristics of the lesion provided by the five institutions, except for the variable proportion of black patients affected by the disease. CONCLUSIONS: FOD mostly affects the mandible of middle-aged black women, and its stage is correlated with patient age. Although panoramic radiography is used for diagnosis, the divergence in assessment of the maxilla might indicate that this method is not the most suitable to evaluate this area.
