RIBEIRO, Erika Barboza et al. Simple bone cyst: report of cases. RFO UPF [online]. 2014, vol.19, n.3, pp. 359-363. ISSN 1413-4012.

Introduction: the Simple Bone Cyst (SBC) is classified by the World Health Organization (WHO) as a non-neoplastic lesion related to bones, defined as an intraosseous cyst. The cause and pathogenesis are uncertain and controversial. Most injuries are empty cavities containing no more than a small serous or serosanguineous fluid, with absent epithelial lining. The most affected areas are long and gnathic bones. Among the gnathic bones the mandible is more frequently affected, mainly in the molar and premolar regions. It has an asymptomatic nature, but pain and paresthesia may be reported in some cases. Objective: this paper aims to report three cases of SBC with radiographic manifestations and different therapeutic approaches. Final considerations: the diagnosis of SBC is primarily based on clinical and radiographic features along with surgical findings. Radiographically, it appears as a radiolucent and well-defined lesion, and scalloping may be observed among dental roots. Lesion curettage is the indicated treatment, with postoperative radiographic follow-up for proservation of the case, or in cases where the clinical and radiographic features are quite suggestive, proservation alone may be advised.
