Protection of vital tissue, especially pulp tissue, is essential to any restorative dental procedure. This study observed the temperature changes in the pulp chamber one minute after application of heat of different degrees to composite and amalgam cores and period of time necessary for the temperature measured in the pulp one minute after heat application to return to 36 degrees C. For this, twelve extracted, morphologically intact human teeth were chosen. Four pins were placed in each of the teeth. Amalgam and composite cores were prepared. All specimens were placed in a water bath at 36 degrees C. Heat of 0 degree C, 40 degrees C, 60 degrees C, 80 degrees C was applied to the cores on the teeth and the temperature of the pulp was measured one minute later by means of a thermocouple. For both amalgam and composite cores, the lowest increase in the pulp temperature was established after the 40 degrees C heat application.
保护重要组织，尤其是牙髓组织，对任何牙齿修复手术都至关重要。本研究观察了对复合树脂和银汞合金核施加不同程度热量一分钟后牙髓腔内的温度变化，以及施加热量一分钟后牙髓测量温度恢复到36摄氏度所需的时间。为此，选取了12颗形态完整的拔除人类牙齿。每颗牙齿植入4根桩。制备银汞合金和复合树脂核。所有标本置于36摄氏度的水浴中。对牙齿上的核施加0摄氏度、40摄氏度、60摄氏度、80摄氏度的热量，一分钟后通过热电偶测量牙髓温度。对于银汞合金核和复合树脂核，施加40摄氏度热量后牙髓温度升高最低。
