Teeth

669
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Tooth Anatomy

1.0K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

概括

学生发现人工牙 (AT) 对于内牙科培训有用,但在复制自然牙 (NT) 触觉反和内部解剖学方面存在局限性. 需要进一步开发AT以更好地模仿NT特征.

科学领域:

  • 牙科教育 牙科教育
  • 牙周内科医院 牙周内科医院 牙周内科医院
  • 生物材料是一种生物材料.

背景情况:

  • 临床前内学培训传统上使用天然牙 (NT),这在可用性和标准化方面存在挑战.
  • 人造牙 (AT) 和三维 (3D) 打印模型为标准化牙科教育提供了潜在的替代方案.
  • 评估学生的看法对于评估新培训材料的有效性至关重要.

研究的目的:

  • 评估牙科学生在内牙科临床前培训中对人工牙 (AT) 的看法.
  • 审查关于学生对3D打印模型在内牙教育中的看法的文献.
  • 确定当前牙科培训模式的挑战和改进领域.

主要方法:

  • 一个24个问题的利克特比例调查问卷评估了学生的看法,比较了AT和NT在内牙程序中.
  • 在PubMed,MEDLINE,Scopus和Web of Science进行了全面的文献搜索.
  • 关键词包括内牙科,天然牙,人工牙,3D打印牙,教学,临床前培训和牙科教育.

主要成果:

  • 学生们更喜欢AT的外观解剖学,辐射透明度,易于获取,卫生和程序简单性.
  • 对AT的负面看法包括内部解剖学,脉腔大小,通道形态,辐射透明度和手术期间的触觉反.
  • 与NT相比,学生发现AT不足以充分理解内牙技术.

结论:

  • 在牙科培训中,TA提高了标准化和效率,但不能完全复制NT的触觉反或解剖准确性.
  • 在模仿触觉和辐射透明度方面的局限性突显了需要改进AT开发的需要.
  • 在牙科教育中,在牙科技术方面的持续创新对于弥合模拟和自然牙特征之间的差距至关重要.
