The coefficient of thermal expansion of specimens from 60 freshly extracted sound human teeth was measured by a dilatometer over the range 10-80 degrees C. The coefficient increased rapidly above 50 degrees C, but there was no significant variation with the tooth age between 10 and 70 years. At 10-50 degrees C, the coefficient of thermal expansion was almost constant. The human teeth are usually at this temperature range in oral cavity. The authors suggest that the average values obtained can be used as quotable values.
用膨胀仪在10至80摄氏度范围内测量了60颗新鲜拔除的健康人牙标本的热膨胀系数。该系数在50摄氏度以上迅速增加，但在10至70岁之间，热膨胀系数随牙齿年龄没有显著变化。在10至50摄氏度时，热膨胀系数几乎恒定。人类牙齿在口腔中通常处于这个温度范围。作者建议所获得的平均值可作为可引用的值。
