Abstract

Introduction: This study investigated the impact of implementing hydraulic condensation (HC) as a second obturation technique in the Endodontic Preclinical course for dental students trained in warm vertical compaction (WVC).

Methods: A total of 70 students performed root canal treatment of 2 extracted molars; they performed the HC technique for the first time after a demonstration. The combination of the obturation technique (WVC or HC) and the type of molar (maxillary or mandibular) was randomly assigned, resulting in 4 groups (n = 35). The students answered a questionnaire appraising their learning experience and completed a self-evaluation rubric. Masked instructors graded projects. Data were statistically analyzed (significance set at 5%).

Results: Most of the students (91%) considered learning 2 obturation techniques relevant and considered it difficult to perform the downpack in molars (P < .05). About half of the students (45.7%) responded that HC resulted in fewer errors and disagreed that WVC derives in a more homogeneous obturation; accordingly, 52.9% of the students selected the highest self-grading for HC obturations, while only 38.6% for WVC. No significant difference was found in the distribution of grades attributed by students and instructors (P > .05). Students reported significantly higher levels of confidence for HC and difficulty for WVC (P < .05). No difference was found between the techniques regarding the presence of voids. The presence of multiple errors was more frequent for WVC (P < .05).

Conclusion: The findings indicate a positive learning experience and comparable performance among preclinical dental students in implementing HC as an alternative obturation technique.

在牙髓病临床前培训中教授一种新的封固技术:对学生学习经历、表现和自我评价的评估。
简介:本研究调查了在牙髓病学临床前课程中将液压冷凝(HC)作为第二种封闭技术对接受温垂直压合(WVC)培训的牙科学生的影响:本研究调查了在牙髓病学临床前课程中将液压冷凝(HC)作为第二种封闭技术对接受过温热垂直压合(WVC)培训的牙科学生的影响:共有 70 名学生对两颗拔出的臼齿进行了根管治疗;他们在示范后首次使用了液压冷凝技术。封固技术(WVC 或 HC)和臼齿类型(上颌或下颌)的组合是随机分配的,结果分为四组(n=35)。学生们回答了一份评估其学习经历的问卷,并填写了一份自我评估表。蒙面教师对项目进行评分。对数据进行了统计分析(显著性设定为 5%):大多数学生(91%)认为学习两种封髓技术是有意义的,并认为在磨牙中进行下包扎是困难的(P0.05)。学生们对 HC 的信心和对 WVC 的难度都明显较高(p 结论:研究结果表明,临床前牙科学生在将 HC 作为一种替代性充填技术时有积极的学习体验和可比的表现。

期刊介绍: The Journal of Endodontics, the official journal of the American Association of Endodontists, publishes scientific articles, case reports and comparison studies evaluating materials and methods of pulp conservation and endodontic treatment. Endodontists and general dentists can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation in the one journal that helps them keep pace with rapid changes in this field.
