Educational teaching of the diagnosis of resorbed root for pulpectomy in deciduous teeth radiography has always been a big challenge in pediatric dentistry. The purpose of the study was to propose a new practical methodology to improve the quality of learning in students of dentistry.
Extracted deciduous teeth were molded in the transparent epoxy resin as their real position in the jawbone. Then, their own pre-extraction radiographs were attached to them. Forty dental students were randomly allocated to the control group of conventional teaching and experimental group of natural model training. All participants were attended in a validated exam and the data were analyzed. A questionnaire was designed with an answer choice in Lickert scale to measure the students' attitude towards the new method and finally the data were reported with descriptive statistics.
The mean of the learning degree in the experimental group was graded 9.2± 3.2 and was significantly higher than 5.8± 1.1 which belongs to the participants of the conventional method as control (p= 0.04 <0.05).
Considering the limitation of this study, using natural models in radiography training will improve the diagnostic competency and the student's educational satisfaction in pediatric dentistry.
在乳牙X线摄影中，关于牙髓摘除术时吸收根诊断的教学在儿童牙科领域一直是一项重大挑战。本研究的目的是提出一种新的实用方法，以提高牙科专业学生的学习质量。
将拔除的乳牙按照其在颌骨中的实际位置用透明环氧树脂进行塑形。然后，将其拔牙前的X线片附着在上面。40名牙科学生被随机分配到传统教学对照组和自然模型训练实验组。所有参与者都参加了一项经过验证的考试，并对数据进行了分析。设计了一份采用李克特量表进行答案选择的问卷，以衡量学生对新方法的态度，最后用描述性统计方法报告数据。
实验组的学习程度平均评分为9.2±3.2，显著高于作为对照组的传统方法参与者的5.8±1.1（p = 0.04<0.05）。
考虑到本研究的局限性，在X线摄影训练中使用自然模型将提高儿童牙科领域的诊断能力和学生的教育满意度。
