摘　　要：目的:研究袋形术对牙源性角化囊性瘤(KCOT)患区牙的影响,为患区牙的保存治疗提供依据。方法:将42例患者分为两组,A组行一期袋形术+二期刮除术,B组行单纯刮除术。术后每3个月复诊1次,术前及复诊时分别检查并记录受累牙的临床状况(松动度及牙髓活力)。结果:42例KCOT病变内受累牙共计237颗。A组患者的受累牙总保存率为92.66%,与B组的91.4%相比无明显统计学差异,其中Ⅰ-Ⅱ°松动受累牙保存率分别为:A组(100%),B组(78.57%)。A组的受累牙牙髓活力保存率71.56%,明显高于B组的36.72%(P<0.01)。结论:一期袋形术+二期刮除术相比单纯刮除术而言,可较多恢复受累牙的稳固、保存牙髓活力,有利于长期发挥正常咀嚼功能。Objective： To study the effects of marsupialization on the teeth involved in keratocystic odontogenic tumor（KCOT）.Methods： A total of 42 patients with KCOT were divided into two groups.The study group was treated with marsupialization in combination with secondary enucleation,while the control group was treated with simple enucleation.Postoperative follow up were carried once every 3 months.The clinical findings of the involved teeth（tooth mobility and dental pulp vitality） were examined before the operation and at follow-ups.Results： There were 237 teeth involved in 42 patients with KCOT.Total teeth preservation had no statistical differences between the two groups,as 92.66% in study group versus 91.40% in control group,including 100% and 78.57% mobile teeth（tooth mobility： Ⅰ-Ⅱ°） respectively in study group and control group respectively.Pulp vitality in the study group（71.56%） was significant higher than that with simple enucleation（36.72%）（P〈0.01）.Conclusion： Compared to the simple enucleation,marsupialization in combination with secondary enucleation has a higher pulp vitality rate and the stability of the teeth involved in KCOT.
