Abstract

Aims and Objectives:Temperature rise may affect on the bone health. The alkaline phosphatase inactivation within the bone has been related with increase of temperatures, around 56 °C. This study assessed the effect of root canal space instrumentation on the temperature elevation on root dentin.

Method:Twenty extracted human teeth had thermocouplesadhered to the outer proximal root surface. The temperature elevation was recorded during the root canal preparation. The samples were divided into two groups (n=10), according to the type of root canal preparation motion; rotation or reciprocation.

Results:Data were subjected to a t-test (α=0.05). The rotary preparation was caused the higher temperature alteration(2.6±0.5°C) than the reciprocation preparation (1.5±0.3°C).

Conclusion: Typeof root canal preparation motion had different thermal alteration on root canal surface.
