Typical results of the temperature measurement. a) Superposition of the temperature rise during 1st (Total) and 2nd (Irradiation) irradiation allows the calculation of reaction exotherm (inset shows the data in the first 100 s). b) Triplicate measurements of temperature rise for the cured TPH and the prepared composite paste without photo-initiator under the same irradiation conditions. Shaded regions indicate irradiation time.
