Clinical, demographic, and radiographic analysis of 82 patients affected by florid osseous dysplasia: an international collaborative study.

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.

Osseous dysplasia (cemento-osseous dysplasia) of the jaw bones in western Pennsylvania patients: analysis of 35 cases.

OBJECTIVES: The purpose of this study is to analyze the demographic, clinical, and radiographic presentations of osseous dysplasia of the jaws in western Pennsylvania patients and its associated complications. MATERIALS AND METHODS: The clinical records and radiographs of patients diagnosed with osseous (cement-osseous) dysplasia were retrieved from the electronic health record of the University of Pittsburgh, School of Dental Medicine from 2007 to 2012. All cases were reviewed; the WHO criteria and classification for osseous dysplasia was used. Clinical and demographic data, radiographic findings, and final diagnoses were collected and analyzed. RESULTS: 35 cases of osseous dysplasia were retrieved over the six-year period.The majority (33) were females [94.3%], with ages ranging from 26 to 89 years, with a mean age of 53.9 years +/- standard deviation of 15.6 years, 32 [91.4%] were African Americans and 3 [8.6%] were Caucasians. 17 [48.6%] were florid osseous dysplasia, 13 [37.1%] periapical osseous dysplasia and 5 [14.3%] focal osseous dysplasia. Of the 35 patients only 8 [22.9%] patients were symptomatic. All florid osseous dysplasia patients were African American females, with 7 of the patients being symptomatic and the commonest symptom being pain. Also, all periapical osseous dysplasia patients were African Americans (12 females and 1 male), with 1 of the patients presenting with widening of the diastema. Of the focal osseous dysplasia patients, 3 were Caucasians and 2 African American (4 females and 1 male). CONCLUSION: The cases occurred mostly in African American females with a peak incidence in the fifth and sixth decades of life; most cases occurred in the mandible. The commonest form of osseous dysplasias was the florid osseous dysplasia which is most likely to present with symptoms.

Benign fibro-osseous lesions of the jaws: a study of 127 Chinese patients and review of the literature.

The aim of this study is to analyze all the cases of benign fibro-osseous lesions treated at School and Hospital of Stomatology, Wuhan University, to compare the results obtained in this study with those previously documented by other authors. The 127 cases diagnosed as a fibro-osseous lesion were retrieved, and information about these lesions was documented. In all, 127 cases of benign fibro-osseous lesions were surgically treated. Of these, 55 were cemento-ossifying fibroma, 43 ossifying fibroma, and 29 fibrous dysplasia. Cemento-ossifying fibromas mostly occur in men of the second decades, mostly in the mandible. Ossifying fibromas had almost equal sex predilection and age distribution peaked in the second decades, mostly in the mandible. Fibrous dysplasia also had equal sex predilection, and age distribution peaked in the second and third decades, with equal occurrence in both jaws. The tumors needed to have a regular follow-up after the surgery.

Osteomyelitis and fibrous dysplasia of the jaw in the negro (abstract only)

During the last three years six cases of Sclerosing Osteomyelitis of the jaws came under observation. They showed clinically and rontgenologically a uniform picture of sclerotic areas in the mandible and sequester formation. The cases described in the literature and all our cases are negroes, women and fortyfive (45) years old and older. No general disease as cause could be found - sickle cell anaemia was excluded. The histo-pathological survey by John Arneaud points out similarities with Fibrous Dysplasia and the possibility of these lesions being different stages of the same process (AU)
