【摘要】：目的：观察犬上颌前牙区在人工模拟残根后周围牙龈软组织的自我修复能力。方法：在犬的上颌前牙区（右上颌侧切牙,左上颌中切牙）制造残根模型，将牙冠磨至龈缘下约平齐牙槽嵴顶水平，避免磨损牙龈软组织，术后第1,3,4,5周观察其牙龈生长情况，测量龈乳头至邻牙牙尖顶的距离、龈乳头至邻牙牙尖顶的水平面的垂直距离、龈缘中点至邻牙牙尖顶的距离、龈缘中点至邻牙牙尖顶的水平面的垂直距离。利用SPSS软件对测量的实验数据进行统计学绘图分析。结果：术后第4周增生的软组织基本长满残根断面，术后第5周新生的软组织与正常牙龈在颜色、质地上基本一致。通过统计学分析在观察周期内牙龈软组织增生的总体趋势是朝着增生方向发展。结论：牙龈在无损伤的情况下具有一定的自我修复能力。4周时残根周围的牙龈软组织可基本完成修复。
[Abstract]:Objective: to observe the self-repairing ability of gingival soft tissue around the maxillary anterior teeth in dogs. Methods: the residual root model was made in the canine maxillary anterior incisor (right maxillary lateral incisor, left maxillary central incisor). The crown was ground to the top of the alveolar crest under the gingival margin to avoid abrasion of the soft tissue of the gingival. The gingival growth was observed at the 1st week and the 3rd week after operation. The distance from the gingival papilla to the cusp of the adjacent tooth, the vertical distance from the gingival papilla to the cusp of the adjacent tooth, and the distance from the midpoint of the gingival margin to the cusp of the adjacent tooth were measured. The vertical distance from the midpoint of the gingival margin to the horizontal plane of the cusp of the adjacent teeth. The measured experimental data were analyzed by SPSS software. Results: at the 4th week after operation, the proliferative soft tissue was basically covered with the residual root section, and the new soft tissue and the normal gingiva were in color at the 5th week after operation. Through statistical analysis, the general trend of gingival soft tissue hyperplasia in the observation cycle is toward the direction of proliferation. Conclusion: the gingival soft tissue around the residual root can be repaired basically at 4. 4 weeks.
