Radicular cysts arising from primary teeth are rare. Enucleation and marsupialization or decompression are treatment approach to odontogenic cysts. Decompression known to achieve good results in various cysts is widely used in clinic. This study aims to evaluate the efficiency of decompression in reducing radicular cysts associated with primary teeth in children.
Cases of radicular cysts associated with primary teeth treated by decompression were reviewed in the present study. Clinical information and radiologic data of pre and post decompression were measured and analyzed.
Twenty-three patients treated for 25 cysts were included. All lesions with mean initial area 3.66 ± 2.00 cm were reduced after decompression time ranging 2 to 10 months. Mean rate of reduction was 0.77 ± 0.44 cm/mo and large lesions (> 3.5 cm) had a significantly higher reduction rate compared to smaller ones (< 3.5 cm) (P < 0.00). All effected succedaneous teeth erupted after treatment at follow-up while 12 (46%) of them had root development problems.
Decompression represents superiority as an effective and less invasive treatment in radicular cysts associated with primary teeth.

由乳牙引起的根尖囊肿较为罕见。牙源性囊肿的治疗方法包括切除囊肿和袋形手术或减压术。减压术在各种囊肿中已被证明能取得良好的效果，因此在临床上广泛应用。本研究旨在评估减压术在减少儿童乳牙相关根尖囊肿方面的效果。
本研究回顾性分析了接受减压术治疗的与乳牙相关的根尖囊肿病例。测量和分析了减压术前和减压术后的临床信息和影像学数据。
本研究共纳入 23 例患者的 25 个囊肿。所有病变的初始平均面积为 3.66±2.00cm，经 2 至 10 个月的减压治疗后均有缩小。平均缩小率为 0.77±0.44cm/月，且较大病变（>3.5cm）的缩小率明显高于较小病变（<3.5cm）（P<0.00）。所有受影响的继生恒牙在治疗后萌出，其中 12 颗（46%）存在牙根发育问题。
减压术作为一种有效且微创的治疗方法，在治疗与乳牙相关的根尖囊肿方面具有优势。
本研究在上海交通大学医学院附属第九人民医院伦理委员会进行了回顾性注册（注册号：SH9H-2022-T158-1）。
