title: [A study on feasibility of the GR phenolaldehyde resinifying agent].
abstract: According to the technological requirements of synthesizing resin and the properties of the resinifying agent, glutaraldehyde, resorcinol and sodium hydroxide with an optimal ratio was selected as a new resinifying agent. The GR resin solidified usually within 20 to 30 minutes, which was suitable to clinical use. Histologic study indicated that GR could resinify living tissues and the residual and infected pulpal tissue in root canals. It not only filled the main canals and sealed the apical foramen, but also infiltrated into the accessory canals and fine branches of canals. The permeating distance of GR in dentinal tubules was short. The results showed GR had the basic properties of resinifying agent.
