OBJECTIVE
The aim of this study was to evaluate temperature alterations on the outer root surface during post space preparation with six different post drills by using an infrared thermometer.
MATERIALS AND METHODS
Sixty extracted single-rooted human mandibular incisor teeth were used. After root canal obturation, the specimens were divided into six groups (n = 10). During post space preparation, the temperature rises were measured in the middle third of the roots using a noncontact infrared thermometer with a sensitivity of 0.1°C. The temperature data were transferred from the thermometer to the computer and were observed graphically.
RESULTS
The maximum temperature rise was observed in Snowpost 2 (29.95 ± 10.2°C) (P < 0.001), but there were no significant differences among Snowpost 2 (29.95 ± 10.2°C), Snowpost 1 (24.6 ± 8.0°C), and Relyx 2 (17.68 ± 9.1°C) (P > 0.05).
CONCLUSIONS
Although water coolant used, the critical temperature rise was observed on the outer root surface in all post drill systems.
目的
本研究的目的是通过使用红外温度计评估六种不同桩钻在桩道预备过程中外侧牙根表面的温度变化。
材料与方法
使用60颗拔除的单根人下颌切牙。根管充填后，将标本分为六组（n = 10）。在桩道预备过程中，使用灵敏度为0.1°C的非接触式红外温度计在牙根中1/3处测量温度升高。温度数据从温度计传输到计算机并以图形方式观察。
结果
在Snowpost 2中观察到最大温度升高（29.95 ± 10.2°C）（P < 0.001），但Snowpost 2（29.95 ± 10.2°C）、Snowpost 1（24.6 ± 8.0°C）和Relyx 2（17.68 ± 9.1°C）之间无显著差异（P > 0.05）。
结论
尽管使用了水冷，但在所有桩钻系统中，外侧牙根表面均观察到临界温度升高。
