Radicular cysts are rarely present in the primary dentition because of the distinct biological cycle of primary teeth. Cyst formation in children may cause bony expansion and resorption, malposition, delayed eruption, enamel defects, or damage to the developing permanent successors. Various treatment modalities for the management of radicular cysts have been reported in the literature. In this case, the preferred treatment approach is window decompression surgery (WDS) combined with gap retainers. Long-term follow-up revealed good healing of the bony lesion. The present case involved an abnormally large radicular cyst in a 7-year-old girl. After surgery, WDS was performed, and a gap retainer was provided. At the 9-month follow-up, the radicular cyst had healed and the impacted tooth had erupted. The aim of this study was to explore the clinical effectiveness of WDS for impacted teeth within root radicular cysts.
由于乳牙独特的生物周期，根囊肿在乳牙列中很少见。儿童囊肿形成可能导致骨质膨胀和吸收、牙齿错位、萌出延迟、釉质缺陷或对发育中的恒牙胚造成损害。文献中报道了多种治疗根囊肿的方法。在本病例中，首选的治疗方法是开窗减压术（WDS）联合间隙保持器。长期随访显示骨病变愈合良好。本病例涉及一名7岁女孩的一个异常大的根囊肿。手术后，进行了开窗减压术，并安装了间隙保持器。在9个月的随访中，根囊肿已愈合，阻生牙已萌出。本研究的目的是探讨开窗减压术治疗根囊肿内阻生牙的临床疗效。
