为论证含有抗菌药的脱矿异体骨治疗牙源性感染性颌骨缺损的效果.用36只家兔做实验,在下颌形成多孔骨缺损腔直径10mm,并切除2～3个牙根,随后发生牙源性感染.动物分3组,第1组骨缺损腔充填血块.第2组骨腔充填用0.25％福尔马林保存的异体骨碎片.第3组充填被抗菌液(二甲亚砜合剂)浸泡的脱
To demonstrate the effectiveness of demineralized allogeneic bone with antibacterials in the treatment of odontogenic mandibular defects, experiments were performed in 36 rabbits to create a porous bone defect with a diameter of 10 mm in the mandible and 2 to 3 root excision followed by The animals were divided into 3 groups, the first group was filled with blood clots, the second group was filled with allogeneic bone fragments stored with 0.25% formalin, the third group was filled with antibacterial liquid (dimethylsulfoxide Mixture) soaked off
