The dental lesions of periodontitis, periodontal cysts, and tooth extraction were studied by Tc-99m phosphate scintigraphy of the jaws. Inflamed apical periodontal lesions caused a localized area of increased concentration of radiotracer regardless of the presence or absence of symptoms. Scintigrams may be positive up to eight months after dental extractions but tend to return to normal thereafter unless complications arise.
通过颌骨的锝-99m磷酸盐闪烁扫描术研究了牙周炎、牙周囊肿和拔牙后的牙齿病变情况。无论有无症状，根尖周炎炎症病变都会导致放射性示踪剂浓度局部升高。拔牙后长达八个月，闪烁扫描图可能呈阳性，但此后除非出现并发症，否则往往会恢复正常。
