对小猎犬造成大面积环状牙周骨缺损,4周后多数根面的愈合是结缔组织修复.占缺损的90%,牙骨质和牙槽骨的再生占缺损的20～30%,每一个根面均表现根吸收,只有1/3有骨粘连。故认为评价牙周修复方法从以下几方面考虑:(1)牙骨质在根面沉积的增多;(2)新骨再生增加,(3)防止牙根吸收和骨粘连等 The beagle caused a large area of ​​ring-shaped periodontal bone defects, most of the root surface after 4 weeks of healing is connective tissue repair accounted for 90% of defects, cementum and alveolar bone regeneration accounted for 20 to 30% of defects, each A root surface showed root absorption, only 1/3 of bone adhesion. Therefore, the evaluation of periodontal repair methods from the following considerations: (1) cementum root deposition increased; (2) increased regeneration of new bone; (3) to prevent root resorption and bone adhesion
