Focal cemento-osseous dysplasia: a systematic review

OBJECTIVES

To evaluate the principal features of focal cemento-osseous dysplasia (FocCOD) by systematic review (SR) and to compare their frequencies between four global groups.

METHODS

Alternative names for FocCOD were used as search terms. The databases searched were the PubMed interface of Medline and LILACS (Literature Index for Latin-America and the Caribbean; Biblioteca Regional de Medicina (BIREME)). Only those reports of FocCODs which occurred in a series in the reporting authors' caseload were considered. All cases used radiographs and were confirmed fibro-osseous lesions histopathologically.

RESULTS

Of the 20 series considered, 10 were included in the SR. Five SR-included series were of East Asian communities. 64% of all SR-included cases were found incidentally. FocCOD predominantly affects females and the mandible. The three predominant radiological presentations varied significantly between reports.

CONCLUSIONS

The two at-risk global communities appear to be East Asians and those of black African origin. Although there appears to be little difference between East Asians and non-East Asians, the significant differences between them with regards to the predominant radiological presentation could suggest that either all communities vary in their presentation or that most, if not all, did not reflect the true frequency within their communities. Long-term follow-up of large series that would have revealed the long-term outcomes of FocCODs was lacking. This is necessary because of both FocCOD's predilection of edentulous areas, increasingly required for osseointegrated implants, and its wide differential diagnosis, which includes some lesions normally treated by surgery.

Florid cemento-osseous dysplasia: a systematic review

OBJECTIVES

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.

METHODS

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.

RESULTS

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.

CONCLUSION

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.
