碘仿预防下颌阻生智齿拔除后干槽症的临床研究

目的 观察碘仿明胶海绵在预防下颌生智齿拔除术后干槽症的效果。方法 随机选择无明显全身系统性急慢性疾病，年龄介于20岁至30岁男性，非完全埋伏性阻生智齿，近15d内无急性冠周炎病史的下颌阻生智齿拔牙患者，拔牙窝内采用盲法用药，用碘仿明胶海绵(A组)，预防干槽症，并选择拔牙后用明胶海绵(B组)和未作预防性填塞(C组)作对照，观察各组术后干槽症发病情况。结果 A组干槽症发生率明显低于B组和C组(P＜0.01)，B组和C组比较无显著性差异(P＜0．05)，在适应性方面A组优于B、C组(P＜0．05)。结论 下颌阻生智拔除后用碘仿明胶海绵作预防性填塞有助于减少于槽症的发生，在一定程度上可基本消除干槽症。

Clinical Experiment on Prevention of Dry Gelatin Sponge of Iodoform after Extraction of Impacted Tooth of Mandible

Objective To observe the effect gelatin sponge of iodoform in prevention of dry socket after extraction of impacted tooth of mandible. Method Male patients aged 20 -30, having no acute or chronic illness, having uncompleted impacted teeth, having no acute peri-coronitis were divided into group A(gelatin sponge of iodoformwas used), group B(gelatin sponge was used) and group C( nothing was used) to prevent dry socket by blind method and the rates of dry socket attack were observed of each group. Results Group B and group C showed no significant difference(P>0.05) but group A had an obvious low rate compared with group B and group C( P<0. 01). Group A had better adaptability than group B and group C( P<0.05) . Conclusion Gelatin sponge of iodoform can reduce dry socket attack after extraction of impacted tooth of mandible and even can eliminate it.
