Objective:
To determine whether spontaneous resolution of simple bone cysts (SBC) is possible.
Methods:
Ten patients were diagnosed as SBC on clinical and radiographic criteria and followed up for 1 to 7 years (mean 3.8). The degree of resolution was assessed subjectively by four radiologists and objectively by changes in the grey level histogram.
Results:
All cases remained asymptomatic over the follow-up period. One of the lesions was considered static, two were increased, six remodeled and one resolved. The mean difference in grey levels between the lesion and the contralateral normal mandible decreased in 8 out of 10 cases.
Conclusion:
It is probable that SBC resolves spontaneously. A protocol for clinical and radiographic diagnosis and follow-up is proposed.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
