Jaw cyst is the most common pathology in the oral and maxillofacial region. The management of the teeth involved in cystic lesions is highly controversial. However, if the teeth involved in the cystic lesion could be preserved with their pulp vitality, the life span of these teeth will be considerably lengthened to improve the masticatory function of these patients after surgery. The present retrospective study over 10 years; with 92 patients that had cystic lesions of the jaws aimed to evaluate the effect of marsupialization on the preservation of the vitality teeth involved in the cystic lesion before and after treatment taking.
clinical retrospective study between January 2013 and January 2022, included 92 patients with a cystic lesion of jaw treated by marsupialization were carried out. The clinical data were collected; the number of teeth involved in the cystic lesion, the vitality of these teeth before and after marsupialization, the number of teeth that have undergone root canal treatment, the number of cases of failure (teeth that were extracted during surgery to open the cystic lesion and teeth that were extracted after surgery) as well as the duration of treatment for each patient were assessed.
Of 92 patients, 54 were men and 38 women with ages ranged from 7 years to 62 years were enrolled in this study.380 teeth were involved in the cystic lesion of that 352 teeth were positive and 28 teeth were negative before marsupialization. 28 teeth underwent root canal treatment before surgery. After surgery, 338 teeth were positive and 42 were negative. Among the 42 negative teeth, 31 teeth failed (extracted) and 11 teeth recovered their vitality before the end of the treatment.321 teeth were saved and preserved their pulp vitality.
The effect of marsupialization is good; it saves and preserves the vitality of the teeth involved in the cystic lesion and it reduces the cost of treatment for the patients.
颌骨囊肿是口腔颌面区域最常见的病变。涉及囊肿病变的牙齿的处理存在很大争议。然而，如果能够保留涉及囊性病变的牙齿及其牙髓活力，这些牙齿的寿命将大大延长，从而改善这些患者术后的咀嚼功能。本回顾性研究超过 10 年，共纳入 92 例颌骨囊性病变患者，旨在评估治疗前后开窗术对保留囊性病变涉及的活力牙齿的效果。
对 2013 年 1 月至 2022 年 1 月接受开窗术治疗的 92 例颌骨囊性病变患者进行临床回顾性研究。收集临床资料：涉及囊性病变的牙齿数量、开窗术前后这些牙齿的活力、根管治疗的牙齿数量、失败的病例数（手术中打开囊性病变时需要拔除的牙齿和手术后拔除的牙齿）以及每位患者的治疗时间。
92 例患者中，男 54 例，女 38 例，年龄 7 岁至 62 岁。380 颗牙齿涉及囊性病变，其中 352 颗牙齿阳性，28 颗牙齿阴性。术前 28 颗牙齿行根管治疗。术后 338 颗牙齿阳性，42 颗牙齿阴性。在 42 颗阴性牙齿中，31 颗牙齿（因病变）需要拔除，11 颗牙齿在治疗结束前恢复活力。321 颗牙齿被保留并保存牙髓活力。
开窗术效果良好，能保留和保存涉及囊性病变的牙齿活力，降低患者的治疗费用。
