The purpose of this study was to measure the changes of temperature in the tooth structures when smoked stopping and pulpr (CCI2F2) were applied on the surface of extracted human teeth.
Twenty extracted human permanent teeth were used for this research. They were clinically intact. A thermography (Agema) and a thermocouple (Hioki) were used and compared in respect of measuing the temperature of the teeth.
The changes of temperature were as follows. Smoked stopping ; 2. 2℃, pulper : 1. 4℃ by thermocouple. Smoked stopping : 3. 2℃, pulper : 2. 9℃ by thermography.
From the above results, at first it could be concluded that the thermography was more useful to know the time-depending thermal conduction on the sectioned tooth surface, and it was more accurate than the thermocouple about the temperature on the surface. And secondly the thermal pulp testing with either smoked stopping or pulper seemed to be not harmful to the dental pulp as long as the tooth was intact.
