In the absence of syndromes, bilateral dentigerous cysts (DC) located on the jaws are unusual. In English based language literature review, we only found eight reports of nonsyndromic bilateral dentigerous cyst associated with mandibular third molars. Therefore, we report the unusual occurrence of sizable nonsyndromic bilateral DC associated with mandibular impacted third molars in a 42-year-old Caucasian woman. The lesions were assessed by cone beam computed tomography (CBCT) the right lesion showed approximately 23.64 mm and the left one, 16.57 mm diameter, both located intimately next to the mandibular canal. Bilateral surgical enucleation, related teeth excision of both third molars and plate for fixation placement on the right and bigger lesion, under general anesthesia was the final treatment choice. Clinical, radiographic and histopathological features confirmed diagnose of bilateral dentigerous cyst. Now-a-days, the patient is on 18 months radiograph follow-up with favorable osseous formation with no evidence of recurrence of the cysts.
在没有综合征的情况下，双侧牙源性囊肿（DC）位于颌骨是不常见的。在基于英文的文献综述中，我们仅发现八例与下颌第三磨牙相关的非综合征性双侧牙源性囊肿的报告。因此，我们报告了一名42岁白种女性中出现的与下颌阻生第三磨牙相关的相当大的非综合征性双侧DC的不寻常病例。通过锥形束计算机断层扫描（CBCT）对病变进行评估，右侧病变直径约为23.64 mm，左侧病变直径为16.57 mm，两者均紧邻下颌管。最终的治疗选择是在全身麻醉下进行双侧手术摘除、拔除两颗第三磨牙并在右侧较大病变处放置固定钢板。临床、影像学和组织病理学特征证实了双侧牙源性囊肿的诊断。如今，患者已进行了18个月的X线片随访，骨形成良好，无囊肿复发迹象。
