Forty upper human premolar teeth with open (immature) apices were root filled by one of three methods, namely lateral condensation with sealer, automated thermatic condensation with sealer, and automated thermatic condensation without sealer. The completed root fillings were then assessed for apical defects, apical extrusions, radiographic voids, apical seal and surface adaptation. The majority of the results indicate that the automated thermatic technique without sealer produces marginally better root fillings in teeth with open apices than the other two methods. However, it is impossible to say whether this would confer any clinical advantage on the technique. The authors recommend that clinicians who wish to use the automated thermatic technique for condensing gutta-percha become highly proficient before its use on patients.
四十颗人类上颌前磨牙牙根尖孔开放（未成熟），采用三种方法之一进行根管充填，即侧方加压加封闭剂、自动热压加封闭剂和自动热压不加封闭剂。然后对完成的根管充填物进行根尖缺损、根尖挤出物、影像学空洞、根尖封闭和表面适应性评估。大多数结果表明，对于根尖孔开放的牙齿，不加封闭剂的自动热压技术比其他两种方法产生的根管充填效果略好。然而，无法确定这是否会给该技术带来任何临床优势。作者建议，希望使用自动热压技术来充填牙胶的临床医生在用于患者之前要非常熟练。
