Radicular cysts arising from primary teeth are uncommon and, when present as large lesions, may adversely affect the underlying permanent teeth. The purpose of this paper is to describe the management of a very large atypical radicular cyst involving the primary dentition of a nine-year-old boy and causing extensive tooth displacement with transposition of the permanent maxillary left canine between the bicuspids. The root apex of the canine was close to the median level of the lateral border of the nasal cavity and showed incomplete root formation and signs of dilacerations in its apical third. Marsupialization was successfully performed, followed by long-term orthodontic treatment. This interdisciplinary management facilitated the lesion resolution for repositioning of the canine into functional occlusion.
乳牙源性根囊肿并不常见，当囊肿较大时，可能会对下方的恒牙产生不利影响。本文旨在描述一名9岁男孩乳牙列发生的非常大的非典型根囊肿的治疗情况，该囊肿导致恒牙严重移位，上颌左侧尖牙位于双尖牙之间并发生易位。尖牙的根尖接近鼻腔外侧壁的中线水平，根尖发育不完全，根尖三分之一处有弯曲迹象。成功进行了袋形术，随后进行了长期正畸治疗。这种多学科治疗有助于囊肿消退，使尖牙重新定位到功能咬合位置。
