This study aimed to determine the temperature increase on the root surface during warm vertical compaction using three different obturation systems. Forty-five human single-rooted premolars were randomly assigned to one of three experimental groups of 15 teeth each for obturation with a System B unit, an Elements Obturation Unit, or a B&L SuperEndo Alpha II unit. All teeth were filled using the continuous wave of condensation technique with a set temperature of 200 °C. The temperature measurements were made with an infrared camera at 3 s (T0) and 1 min (T1) following activation of the heat plugger. T0 ranged between 48.1 and 84 °C depending on the obturation system. The mean value for T0 showed significant differences between various obturation systems (p = 0.001). The temperature increase on the root surface during the application of vertical compaction shows considerable variability depending on the obturation system.
本研究旨在使用三种不同的根管充填系统确定热垂直加压过程中根管表面的温升。将 45 个人类单根前磨牙随机分为三组，每组 15 颗牙，分别使用 System B 单元、Elements Obturation Unit 或 B&L SuperEndo Alpha II 单元进行根管充填。所有牙齿均采用 200°C 的设定温度进行连续波冷凝技术充填。在热牙胶枪启动后 3 秒（T0）和 1 分钟（T1）时使用红外摄像机进行温度测量。T0 取决于根管充填系统，范围在 48.1 到 84°C 之间。T0 的平均值在不同的根管充填系统之间存在显著差异（p=0.001）。在应用垂直加压时，根管表面的温升取决于根管充填系统，存在相当大的变异性。
