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.

Długotrwała ekspozycja na podwyższone temperatury przekraczające 47°C, które mogą wystąpić podczas wypełniania kanałów korzeniowych, może spowodować uszkodzenie zarówno tkanek zęba, jak i kości. W celu zbadania rozkładu temperatury na powierzchni korzenia zęba zaproponowano urządzenie do pomiaru temperatury z kompensacją zimnego złącza. Do pomiaru in vitro rozkładu temperatury na powierzchni zęba wykorzystano 8 termopar umieszczonych w bezpośrednim kontakcie z cementem zęba. W celu wyeliminowania wahania temperatury zimnego złącza zastosowano urządzenie do wyrównania temperatur oraz czujnik rezystancyjny RTD. Proponowana aproksymacja liniowa funkcji przetwarzania termopary zapewnia względny błąd nieliniowości mniejszy niż 0,05% dla termopar typu K i 0,07% dla termopar typu J w zakresie temperatur od 20 do 60°C.
