医用胶根管充填材料的试验研究

Study of n-octyl-a-cyanoacrylate in root canal therapy

目的探讨医用胶在根管治疗术中堵塞根管的密合程度及作用机制。方法应用显微镜、扫描电镜对医用胶根管充填材料和牙胶尖常规充填材料进行对比研究。结果医用胶根管充填材料在根管中质地均匀,根尖孔及根管壁充填密合。结论医用胶可以作为一种新型根管充填材料,应用于临床根管治疗术。

Objective To discuss the exact degree of filling root canal and the rationale of n-octyl-a-cyanoacrylate in root canal therapy.Methods Microscope and SEM were used to study root canal filling materials,n-octyle-a-cyanoacrylate and gutta percha point,while their effects were compared.Results N-octyl-a-cya noacrylate is well qualified in root canal,and had an exact degree in filling ro ot tip foramen and root canal wall.Conclusion N-octyl-a-cyanoacrylate could be applied as a new root canal filling material in clinical root canal therapy.
