Spontaneous Avulsion of Sequestra from Both Sides of the Mandible in the Same Patient: A Rare Case Report

Background: The goal of therapy is sequestrectomy of necrotic bone in chronic osteomyelitis; spontaneous avulsion of a sequestrum is rare. In its clinical evolution, this devitalized bone, which the sequestrum is, becomes separated from the remaining bone. However, spontaneous avulsion is rare. Case presentation: Two incidents of spontaneous avulsion of sequestra from the bilateral body of the mandible in a female patient at 75 and 78 years old. A history of progressive tooth mobility and subsequent loss of teeth was elicited from this patient; additionally, tooth loss resulted in problematic healing sockets. Conclusion: The complications from bone infection, such as chronic osteomyelitis caused by long-standing periodontitis, could account for the detachment and subsequent avulsion of sequestra in a poorly healing extraction socket seen in this patients .
