Summary
Training dental students on extracted natural teeth significantly improves pulpectomy skills compared to typodont models. This enhances clinical performance in pediatric pulpectomy procedures for better patient outcomes.
Area of Science:
- Pediatric Dentistry
- Dental Education
- Endodontics
Background:
- Pulpectomy is crucial for primary teeth, requiring skilled practitioners.
- Effective training is essential for dental students to master technical skills and hand-eye coordination.
Purpose of the Study:
- To assess and compare the effectiveness of undergraduate training in pulpectomy using typodont models versus extracted natural teeth.
Main Methods:
- 100 final-year Bachelor of Dental Surgery students were divided into two groups.
- Group I trained on typodont teeth, Group II on extracted natural teeth.
- Clinical performance in access cavity preparation, biomechanical preparation (BMP), and obturation was evaluated.
Main Results:
- Students trained on extracted natural teeth demonstrated superior performance in BMP and obturation.
- Higher canal cleaning adequacy (91% vs 87%) and shaping accuracy (93% vs 87%) were observed in the natural teeth group.
- Fewer errors in canal preparation (6% vs 18%) were noted with natural teeth training.
Conclusions:
- Training with extracted natural teeth leads to better outcomes in pulpectomy procedures than using typodont models.
- This method enhances student competency in pediatric pulpectomy, improving dental education and clinical results.

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...

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...
