The temperature rise of the irrigant in the root canal during free vibration of the ultrasonic file was studied in vitro in 10 human teeth. The mean temperature rise was found to be 0.6 degrees C. The minimal temperature increase may not significantly contribute to the effectiveness of ultrasonic root canal instrumentation.
在10颗离体人牙上,对超声锉自由振动期间根管内冲洗液的温度升高进行了体外研究。发现平均温度升高为0.6摄氏度。最小的温度升高可能对超声根管预备的效果没有显著贡献。
