A thermal profile of the warm gutta-percha technique was produced by the thermocouple instrumentation of natural teeth and the subsequent monitoring of intraradicular temperature changes during the packing procedure. Although variations in thermal patterns resulted from individual differences in timing and instrumentation, certain clinically accepted patterns of activity produced consistent, representative temperature ranges to which the gutta-percha in the body of the canal was 80 degrees C., while the over-all peak temperature recorded in the apical region was 45 degrees C. Thermal penetration of the gutta-percha was expectedly limited, with significant thermal effects rarely exhibited more than 4 to 6 mm. into the material.
通过天然牙的热电偶仪器以及在充填过程中对根管内温度变化的后续监测，得出了热牙胶技术的温度曲线。尽管热模式的变化源于时间和仪器的个体差异，但某些临床上公认的活动模式产生了一致的、具有代表性的温度范围，根管体部的牙胶温度为80摄氏度，而根尖区域记录的总体峰值温度为45摄氏度。牙胶的热渗透预期是有限的，显著的热效应很少在材料中表现超过4至6毫米。
