Using polchromatic sequential labeling, the healing of experimentally inflicted root fractures was observed in beagle dogs. A transition through hard substances formed from vascular connective tissue of the periodontium occurred only in the fine fracture line. It was not related to the pulp, since it also appeared after endodontal fixation. A vascular mineralization occurs in the extra-fine tissue which can be reached through a tension screw into the pulp cavity. This mineralization leads to a filling of the fragments. Dislocated root fragments heal incompletely due to interposition of connective tissue.
采用多色序列标记法,在比格犬身上观察实验性造成的牙根骨折的愈合情况。仅在细微骨折线处出现了由牙周膜血管结缔组织形成的硬组织过渡。这与牙髓无关,因为在牙髓固定后也会出现这种情况。通过张力螺钉进入牙髓腔可触及的超细微组织中发生血管矿化。这种矿化导致碎片填充。由于结缔组织的介入,移位的牙根碎片愈合不完全。
