Randomized trial investigates chemical changes in gutta-percha and sealers during heating, suggesting temperature standardization is crucial.

To explore how heating affects different gutta-percha and endodontic sealers and to assess heat carrier capabilities.
Evaluated heating capacity of three endodontic heat carriers using thermocouples for heat profiles.
Analyzed chemical changes in six brands of gutta-percha and four types of sealers using micro-Raman spectroscopy and FT-IR spectroscopy during heating.
Conducted comparisons of Raman spectra at various temperature levels.
Heat carriers did not achieve the set temperature levels recommended by manufacturers.
Continuous heating mode resulted in higher temperatures than the 4 s cut-out mode, reaching 110 °C.
All tested sealers showed changes in chemical composition upon heating, with irreversible changes noted in some cases.
