title: [A new resinifying solution without the effect of discoloring teeth].
abstract: In order to solve the problem of tooth stain caused by phenolformaldehyde resinifying therapy, we have, on basis of theory of the resinifying therapy, prepared a colourless resinifying solution RF-109. Experiments on its chemical and physical properties, ability of becteriostasis, animal tissues reaction including ultra-structure observation after resinified muscles of rats, rabbits and dogs as well as imitate root canal filling have been performed. Results proved that RF-109 is desirable for resinifying therapy. Its peculiarity is that after pulp therapy, the tooth will not be stained. And besides, it is much simpler in preparation, and lower in cost than that of phenol-aldehyde resin. Its preservation is also much easier. The long-term results of RF-109 is satisfactory in 91.30% of 174 cases followed-up for three years.
