Temperature rise at root surface during post-space preparation.

This study compared the changes in temperature at the root surface of extracted human central incisors during post-space preparation using the following reamers (1) Peeso, (2) Kurer, (3) Gates-Glidden, (4) Para-Post, and (5) diamond burs. A mean temperature rise ranging from 2.3 degrees C to 15.6 degrees C from the baseline of approximately 28 degrees C was recorded. Peeso reamers recorded the highest temperatures followed by Kurer system and diamond burs, whereas Gates-Glidden and Para-Post systems were the lowest.
