Abstract
Objectives: To present and discuss the demographic and radiographic aspects of craniomaxillofacial bone islands (BIs) in the population of china. Materials and Methods: A retrospective chart review was performed of all cases of BIs diagnosed in the Department of Oral Radiology in West China College of Stomatology, Sichuan University. The data collected included age at diagnosis, gender, race, location, presenting symptoms, type of BIs. Results: In radiographic evaluation, BIs appear as localized, well-defined, non-expansile, radiopaque masses, which are round, elliptic or irregular in shape and are of variable size, ranging from a few millimetres to about 2 cm in diameter. The results of this study generally supported previous findings that BIs have an overwhelming mandibular predilection, especially, in the pre-molar/molar region, no sex predilection. Conclusions: The presumptive diagnosis of a BI can easily be made if the individual clinical and radiologic findings, together with follow-up examinations, are taken into account. In addition, it is important to recognize this anomaly, evaluate radiographies carefully and distinguish it from other bone variations such as primary or metastatic tumours, which is much more significant clinically in dental examinations.
