骨的疾病,包括上、下颌骨,需要几个月的时间来脱钙才足以使X线照片上表现不正常。其间使患者蒙受疼痛。而放射核素颌骨显影则能在X线照片显示阳性结果之前协助诊断活跃性牙齿感染。因为放射核素骨显影的活性能反映成骨细胞的活性。牙齿的炎性反应和感染诱发了成骨细胞的活性,影响着邻近的骨。这一过程在X线片上表现出明显的骨溶解之前就发生了。在标准的骨显影中,放射性核素的检查在X线片出现阳性结果之前3—4月即可成为阳性,并可保持到牙拔除或根管治疗后18个月。作者报告1例 Bone diseases, including the upper and lower jaws, take several months to decalcify enough to make the X-ray abnormalities. During which the patient suffers from pain. Radionuclide jaw imaging helps diagnose active tooth infections before radiographs show positive results. Because the activity of radionuclide bone development can reflect the activity of osteoblasts. Inflammatory reactions and infections in the teeth induce osteoblast activity affecting adjacent bones. This process occurred before radiographic evidence of significant osteolysis. In standard bone imaging, radionuclide tests become positive 3-4 months prior to the positive results of the radiographs and remain emasculated or 18 months after root canal treatment.
