 note = {P(論文), In endodontics, final treatment of pulpectomy and infected root canal is root canal filling. As for root canal obturating points, miscellaneous properties are required. Although JIS specifies appearance, injurious action, shape and size, fracture resistance, radio-opacity and post disinfection quality, many other properties have been left uninvestigated. In this study, water absorption, surface and internal structure, organic-inorganic component ratio, gas amount left adhering to the point after aeration and the effect of adhering gas on Escherichia coli cultivation were investigated on the commercially available six points. The findings were as follows. The amount of water absorption of the individual point was proportional to the adhering amount of gas. The more porous the structure of the point was the more water absorption there was. The amount of gas left adhering to the point didn't disinfect Escherichia coli. This fact suggests that the obturating point could be effectively gas sterilized at 37℃ and used with biological safety.},
