A comparison of the effects of three chelating agents on the root canals of extracted human teeth.
The effects of EDTA were compared in vitro with the effects of two other chelating agents: succimer and trientine HCl. Thirty extracted human teeth with single canals were used. Groups of 10 were treated by the three agents and then examined under the scanning electron microscope. The results showed that EDTA widened the dentinal tubules. Trientine HCl also produced widening of the dentinal tubules very similar to EDTA, whereas succimer produced more extensive widening.
