摘　　要：目的观察改良ＦＲ牙髓治疗剂用于直接盖髓术后牙髓组织学反应。方法将１２例因正畸需要拔除的恒牙造成人工穿髓孔后用改良ＦＲ制剂行直接盖髓术。术后１至８周将受试牙拔除后作组织学观察。结果术后一周组，牙髓表面出现轻到中度炎症。术后４周组，牙髓表面仍有炎症并出现局部坏死区，同时有钙化带出现。术后８周组，检出修复性牙本质桥，牙髓组织恢复正常。结论改良ＦＲ牙髓治疗剂是一种较理想的盖髓剂。Objective The purpose of this study was to investigate the structures and functions of the gingival fibers and papillary in the human gingiva of the upper molar region.Methods They were observed by a light microscope. Results The results are as follows:①There is a large number of dentogingival fibers in the lingual gingiva of the upper molar region. ② There is a large number of papillary in the lingual gingiva of the upper molar region. Conclusion ①Large number of papillary in the lingual gingiva exists a close relation between the development of the doentogingival fibers of the lingual gingiva and the function in its region. ② It is observed that the tens of the dentogingival fibers extend widely to the epithelial cell of the stratum spinosum.
