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...

Summary
This summary is machine-generated.

Students found artificial teeth (AT) useful for endodontic training but noted limitations in replicating natural teeth (NT) tactile feedback and internal anatomy. Further development is needed for AT to better mimic NT characteristics.

Area of Science:

  • Dental Education
  • Endodontics
  • Biomaterials

Background:

  • Pre-clinical endodontic training traditionally uses natural teeth (NT), which present challenges in availability and standardization.
  • Artificial teeth (AT) and three-dimensional (3D) printed models offer potential alternatives for standardized dental education.
  • Assessing student perceptions is crucial for evaluating the effectiveness of new training materials.

Purpose of the Study:

  • To evaluate dental students' perceptions of artificial teeth (AT) in endodontic pre-clinical training.
  • To review the literature on student perceptions of 3D printed models in endodontic education.
  • To identify challenges and areas for improvement in current dental training models.

Main Methods:

  • A 24-question Likert scale questionnaire assessed student perceptions comparing AT and NT in endodontic procedures.
  • A comprehensive literature search was conducted across PubMed, MEDLINE, Scopus, and Web of Science.
  • Keywords included endodontics, natural teeth, artificial teeth, 3D printed teeth, teaching, pre-clinical training, and dental education.

Main Results:

  • Students favored AT for external anatomy, radiopacity, ease of acquisition, hygiene, and procedural simplicity.
  • Negative perceptions of AT included internal anatomy, pulp chamber size, canal morphology, radiopacity, and tactile feedback during procedures.
  • Students found AT inadequate for fully understanding endodontic techniques compared to NT.

Conclusions:

  • AT enhance standardization and efficiency in endodontic training but do not fully replicate NT tactile feedback or anatomical fidelity.
  • Limitations in mimicking tactile sensation and radiopacity highlight the need for improved AT development.
  • Continued innovation in AT is essential to bridge the gap between simulation and natural tooth characteristics in dental education.
