Temperature diffusion was monitored through in vivo restorations with and without bases 0.5 and 1 mm thick. Temperature diffusion was highest through amalgam restorations and slowest through unfilled resin restorations. The rate of diffusion through composite resins and silicate cement fell between the extremes. Bases of both zinc phosphate cement and zinc oxide-eugenol cement reduced the rate of temperature change on the floor of the cavity beneath amalgam restorations. The temperature change was generally less under the 1 mm base than the 0.5 mm base. Bases used beneath the nonmetallic restorations did not reduce the magnitude of temperature change on the cavity floor.
通过对有和没有0.5毫米及1毫米厚基底的体内修复体进行监测来观察温度扩散情况。温度扩散在汞合金修复体中最高，在未填充树脂修复体中最慢。通过复合树脂和硅酸盐水泥的扩散速率介于两者之间。磷酸锌水泥和氧化锌丁香酚水泥基底均降低了汞合金修复体下方窝洞底部的温度变化速率。1毫米厚基底下方的温度变化通常比0.5毫米厚基底下方的小。非金属修复体下方使用的基底并未降低窝洞底部温度变化的幅度。
