Influences of age and sex on the validity of bone scintigraphy for the diagnosis of temporomandibular joint osteoarthritis

Bone scintigraphy has been used for the diagnosis of early-stage temporomandibular joint (TMJ) osteoarthritis (OA) owing to its high sensitivity. However, the diagnostic value of bone scintigraphy may be compromised when applied to patients in an age range with high bone metabolism rates. The aim of this study was to investigate the validity of bone scintigraphy as an appropriate diagnostic modality for TMJ OA. A total of 406 subjects (145 male, 261 female; age range 14–87 years) were selected, and all subjects underwent both bone scintigraphy and computed tomography (CT).
