Cemento-osseous dysplasia (COD) belongs to a group of fibrous osseous disorders that can masquerade as periapical inflammatory conditions in the jawbones. We present a rare case of COD occurring in a patient who also had periapical periodontitis concurrently. When faced with a patient exhibiting no symptoms, diagnosis may be challenging.
COD is a fibrous osseous disorder similar to periapical chronic inflammatory conditions and other cysts in the jaw bones on the radiograph. There is a rare case of COD occurring in a 49-year-old Chinese woman who also had chronic periapical periodontitis concurrently. The lesions were incidentally discovered in the mandibular anterior tooth region during the patient's imaging examination. The patient exhibited no symptoms, and diagnosing the conditions may be challenging due to the confusingly similar radiological features that present as a radiolucent lesion in the periapical region. The final diagnosis was made through pulp vitality tests, cone beam computed tomography (CBCT), and clinical examinations. The COD was recommended for annual follow-up. Root canal therapy has been performed for chronic apical periodontitis. According to the diagnostic process of COD, a thorough history check, multiple clinical examinations, and imaging studies should be emphasized to prevent misdiagnosis and avoid unnecessary or inappropriate therapies. The patient was followed up for 6 years. The recovery of chronic apical periodontitis in tooth #31 and the transformation of osteolytic and osteogenesis of COD had been observed in CBCT.
骨化纤维瘤（COD）属于一组纤维性骨疾病，可在颌骨中伪装成根尖周炎症性疾病。我们报告了一例罕见的COD病例，该患者同时患有根尖周炎。当面对无症状的患者时，诊断可能具有挑战性。
COD是一种纤维性骨疾病，在X线片上类似于颌骨根尖周慢性炎症性疾病和其他囊肿。一名49岁的中国女性同时患有慢性根尖周炎，出现了罕见的COD病例。病变在患者影像学检查时于下颌前牙区偶然发现。患者无症状，由于根尖区表现为透射性病变的放射学特征相似，诊断这些疾病可能具有挑战性。最终诊断通过牙髓活力测试、锥形束计算机断层扫描（CBCT）和临床检查做出。建议对COD进行年度随访。已对慢性根尖周炎进行根管治疗。根据COD的诊断过程，应强调全面的病史检查、多次临床检查和影像学研究，以防止误诊并避免不必要或不适当的治疗。对该患者进行了6年的随访。在CBCT中观察到31号牙慢性根尖周炎的恢复以及COD的溶骨和成骨转变。
