“…To measure the temperature range during in vitro root canal obturation, various primary temperature transducers such as thermoelectric, thermoresistive or semiconducting ones can be employed [4,[10][11][12]14]. The temperature measurements in separate points on the root surface and inside the root canal can be effectively performed using thermocouples [20,24]. Compactness, wide temperature range, interchangeability, relatively fast thermal response, long term of operation, reliability and affordable price are the main advantages of thermocouples.…”

Prolonged exposure to elevated temperatures exceeding 47°C, which can occur during root canal obturation, can cause damage of both dental and bone tissues. In order to study the temperature distribution on the surface of the tooth root a temperature measuring device with cold-junction compensation is proposed. For in vitro measurement of the temperature distribution on the surface of the tooth, 8 thermocouples placed in direct contact with the cementum of the tooth were used. In order to eliminate the cold-junction temperature variations, the temperature equilibration device and RTD were used. The suggested linear approximation for the thermocouples' conversion function provides a nonlinearity relative error of less than 0.05% for K-type thermocouples and 0.07% for J-type thermocouples over the temperature range from 20 to 60°C.
