Florid cemento-osseous dysplasia: a systematic review

To evaluate the principal features of florid cemento-osseous dysplasia (FCOD) by systematic review (SR), with particular regard to comparison of Oriental with non-Oriental populations, and of reports derived from pathology files with those from non-pathology sources. All alternative names for FCOD were used as search terms for two electronic databases, namely Medline and "Web of Science". Only multiple forms of cemento-osseous dysplasia occurring in a series in the reporting authors' case load were considered. Medline produced more SR-identified reports. The search terms "Cementoma" and "Osseous Dysplasia" were the most effective for both databases. One hundred and fifty-eight cases of FCOD were observed in 17 series of patients reported in 16 SR-identified reports. Fifty-nine percent of cases were found in Blacks, 37% in Orientals and 3% in Caucasians. Ninety-seven percent were females. Fifty percent of cases in the SRs were observed incidentally. Pain was most frequent in those with presenting symptoms, and was significantly more frequent in the Oriental series. In two studies on the same Chinese community, those cases found incidentally on radiographs alone were significantly younger than those with symptoms in the pathology files. The nomenclature for FCOD is extensive, but older and more general terms were more effective in recalling SR-identified reports. Cases in a report based on pathology files appear to be older than those in a report based on radiology alone files. With the exception of a higher prevalence of pain in Orientals, mainly Chinese, there did not appear to be any differences in presentation compared with that observed in Black communities.
