Summary
Preclinical endodontic training on artificial teeth (AT) adequately prepares students for natural teeth (NT) procedures. However, performance on AT does not reliably predict performance on NT, suggesting caution in AT-based assessments.
Area of Science:
- Dental Education
- Endodontics
- Preclinical Training
Background:
- Endodontic training traditionally uses natural teeth (NT).
- Artificial teeth (AT) offer a potential alternative for preclinical endodontic education.
- Evaluating the efficacy of AT versus NT training is crucial for dental curricula.
Purpose of the Study:
- To compare the effectiveness of preclinical endodontic training using solely artificial teeth (AT) versus natural teeth (NT).
- To assess student performance on natural teeth (NT) after training on either AT or NT in an objective structured practical examination (OSPE).
Main Methods:
- A randomized trial allocated 43 dental students to AT (n=20) or NT (n=23) training groups.
- Training involved intraoral root canal treatment on mannequin heads.
- Performance was evaluated via OSPE on both AT and NT, with detailed assessments.
Main Results:
- No significant difference in performance on NT or AT between the AT and NT training groups.
- Students trained on AT performed significantly worse on NT compared to AT, unlike the NT group.
- Performance on AT did not significantly predict performance on NT.
Conclusions:
- Artificial teeth (AT) training appears suitable for preparing students for endodontic treatment on natural teeth (NT).
- Assessment of endodontic skills using AT should be approached with caution.
- Evaluating training success through performance on natural teeth (NT) may be more reliable.

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...

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...
