The aim of this work was to measure and analyze the forces applied by endodontists during an obturation. This was achieved by devising a system of force transducers linked to acquisition software. The software allowed us to study the obturation forces in real time or to store them. In this initial study, the forces developed by endodontists and students during a warm vertical compaction were analyzed. The vertical and frontware backware horizontal direction forces were first stored. Graphs of the compaction forces were then generated, permitting the analysis of the obturation method. Indeed, two cases of obturation failure were analyzed from these graphs. The mean values for the vertical forces applied by the endodontists and students were, respectively, 2.5 +/- 0.4 kg and 1.9 +/- 0.9 kg; the mean values for the lateral forces were, respectively, 0.85 +/- 0.2 kg and 1.4 +/- 0.6 kg. This device permits the analysis of compaction forces and may thus be highly useful in obtaining improvements in obturation techniques.
这项工作的目的是测量和分析牙髓病医生在根管充填过程中施加的力。这是通过设计一个与采集软件相连的力传感器系统来实现的。该软件使我们能够实时研究充填力或存储这些力。在这项初步研究中，分析了牙髓病医生和学生在热垂直加压过程中产生的力。首先存储垂直方向以及前后水平方向的力。然后生成充填力的图表，以便对充填方法进行分析。事实上，从这些图表中分析了两例充填失败的情况。牙髓病医生和学生施加的垂直力的平均值分别为2.5±0.4千克和1.9±0.9千克；侧向力的平均值分别为0.85±0.2千克和1.4±0.6千克。该装置能够分析加压力量，因此在改进充填技术方面可能非常有用。
