The Effect of the Gutta Condensor on Powder-Liquid and Ready-to-Use Hydraulic Sealers

The purpose of this study was to evaluate the increase in internal and external temperature of bovine tooth roots by driving the Gutta Condensor at two different speeds, as well as whether the sealers activation can cause alterations in the chemical structure of Bio-C Sealer and Cimmo HP, through Raman spectroscopy.

To assess the variation in root temperature, 60 bovine teeth were used. They were sectioned to standardize the samples to a length of 12mm, and their canals were prepared using VDW R50. After preparation, the roots were distributed into 12 groups, based on sealer type, use or non-use of gutta-percha, and Gutta Condensor speed. During root canal filling, internal and external temperatures of the roots were measured in all groups. To access the chemical structure, Raman spectroscopy was performed on both thermally activated and non-activated sealer samples (n=2).

It was demonstrated that both the sealer and the gutta-percha influenced the increase in internal and external root temperature. In intragroup comparisons, differences were observed between the speed of the Condensor and the control samples (P < 0.05). Raman spectroscopy showed that both control and activated samples have the same chemical structure.

This study concluded that the Gutta Condensor increases both internal and external temperatures to a non-critical point but does not affect the chemical structure of the sealer.
