Inflammatory lesions, like periapical/odontogenic abscesses, are by far the most common pathologic condition of the jaws. Radiographically, these lesions commonly manifest as widening of periodontal ligament space, discontinuity of lamina dura and ill-defined periapical radiolucency. There are some rare disorders which could cause similar radiographic changes in the jaw bone. With careful scrutiny of periapical radiolucency, regular periodic follow-up radiographs and histo-pathologic examination, the periapical abscess or infection can be differentiated from rare fatal disorders.
This paper highlights the need for vigilant examination of even the commonest, innocuous-appearing periapical changes which sometimes are produced by some rare fatal disorders.
炎症性病变，如根尖周/牙源性脓肿，是目前颌骨最常见的病理状况。在影像学上，这些病变通常表现为牙周膜间隙增宽、硬骨板连续性中断以及边界不清的根尖周透射区。有一些罕见疾病可导致颌骨出现类似的影像学改变。通过仔细观察根尖周透射区、定期进行随访X线片检查以及组织病理学检查，可将根尖周脓肿或感染与罕见的致命性疾病区分开来。
本文强调，即使是看似最常见、无害的根尖周改变也需要进行警惕性检查，因为这些改变有时可能由一些罕见的致命性疾病引起。
