摘要

根状囊肿是口腔中最常见的炎症性牙源性囊肿,但很少发生在乳牙中。乳牙的根状囊肿会导致恒牙的牙根扩张,从而产生阻生恒牙。我们报告了一个11岁的男孩,他接受了乳牙根根囊肿减压引流术,随后进行了牙根扩张的永久继承牙的早期正畸牵引。囊肿愈合顺利,阻生前磨牙逐渐对准牙弓,牙根发育良好。本病例说明及时减压乳牙根状囊肿可有效保护继位恒牙。同时,对于已经发生恒牙嵌塞伴牙根扩张的病例,及时进行正畸牵引,可使牙根从骨皮质向松质骨移动,获得生长空间。

Management of Impacted Premolar With Root Dilaceration Caused by Radicular Cyst in Deciduous Molar: A Case Report.

Radicular cyst is the most common inflammatory odontogenic cyst in the oral cavity, but it rarely occurs in deciduous teeth. Radicular cysts in deciduous teeth can lead to root dilaceration in permanent successor teeth, resulting in impacted permanent teeth. We presented an 11-year-old boy who underwent decompression and drainage of a radicular cyst in deciduous tooth, followed by early orthodontic traction of permanent successor tooth with root dilaceration. The cyst healed successfully, and the impacted premolar was gradually aligned into the dental arch with favorable root development This case demonstrates that timely decompression of radicular cysts in deciduous teeth can effectively protect the successor permanent teeth. Meanwhile, for cases where permanent tooth impaction with root dilaceration has already occurred, timely orthodontic traction can move the root from the bone cortex into the cancellous bone to obtain growth space.
