牙根囊肿是上颌骨前部最常见的牙源性囊肿之一，在年轻人中并不常见。它们主要出现在牙齿的顶端（根尖周囊肿），牙根的侧面（侧根囊肿），并在移除冒犯的牙齿后保留在颌骨中（残留囊肿）。根端囊肿被归类为炎性囊肿，是龋病后牙髓坏死的结果，伴有根尖周炎性反应。他们进展缓慢，无症状，以免感染。正因为如此，它们可以扩展到大尺寸。很多时候，要通过放射学检查将根尖囊肿从已经存在的慢性根尖周炎病变中分离出来是一件令人困惑的事情。在这里，我们介绍了一例罕见的病例，该病例为19岁患者，患有与下颌骨第一磨牙相关的双侧根囊肿。正断层扫描显示左侧第一磨牙根尖周区域有一个大的单房透亮线，边界清晰，从第二前磨牙根部延伸到第二磨牙近中根部。相应地，在下颌骨右侧观察到另一个边界清晰的单房透亮区。几种可能的治疗方法，如外科牙髓治疗，超越牙齿的提取，与一期关闭，和marsupialization后，剜出根囊肿。病人的管理包括手术摘除囊，然后在同一地区的康复。
A radicular cyst is one of the furthermost everyday odontogenic cysts of the anterior maxilla, not regularly comprehended in youth. They are found mostly at the apices of the tooth (periapical cyst), lateral surface of the roots (lateral radicular cyst) and remains in the jaw after removal of the offending tooth (residual cyst). The radicular cyst has been catalogued as an inflammatory cyst, as an outcome to pulpal necrosis succeeding caries, with a linked periapical inflammatory reaction. They advance sluggishly and asymptomatic lest infected. Because of this they can extent to big dimensions. Many times it is perplexing to segregate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. Here, we present a rare case with bilateral radicular cyst in relation to first molar of the mandible in a 19-year-old. Orthopantomograph showed a large unilocular radiolucency with a well-defined border in the periapical region of the first molar on the left side extending from the root of the second premolar to the mesial root of the second molar. Correspondingly another well-defined unilocular radiolucency with a well-defined border was seen on the right side of the mandible. Several treatment possibilities are presented for a radicular cyst such as surgical endodontic treatment, extraction of the transgressing tooth, enucleation with primary closure, and marsupialization trailed by enucleation. The patient management comprised surgical enucleation of cystic sac followed by rehabilitation of the same area.
