title: Simple bone cyst. A clinical and histopathologic study of fifteen cases.
abstract: Nineteen simple bone cysts found in 15 patients were studied by classifying them into younger and older age groups. The clinical, radiographic, and histopathologic features of 11 cysts in the younger group of 10 patients were consistent with those of previous reports. Among patients in the older age group, female predominance (80% vs 30%), involvement of the maxilla (25% vs 0%), multiple occurrence (60% vs 10%), simultaneous presence of radiopaque fibro-osseous lesions or hypercementosis (63% vs 0%), and loss of lamina dura of related teeth (83% vs 14%) resulting in exposure of their roots on surgical intervention were the characteristic features.
