Summary
Three-dimensional (3D) printing offers promising alternatives to natural teeth for endodontic studies. Further research is needed to standardize protocols and address limitations like resin hardness for 3D-printed teeth.
Area of Science:
- Endodontics
- Biomaterials Science
- Manufacturing Technology
Background:
- Natural teeth are the current standard for ex vivo endodontic studies but present limitations.
- Three-dimensional (3D) printing technology offers potential solutions to these limitations.
- Standardization of protocols and understanding of manufacturing processes for 3D-printed teeth are needed.
Purpose of the Study:
- To review the advantages of 3D-printed teeth in endodontics.
- To describe the manufacturing processes involved in creating 3D-printed teeth.
- To identify current challenges and future research directions for 3D-printed teeth.
Main Methods:
- Literature review focusing on 3D-printed teeth in endodontics.
- Analysis of advantages, manufacturing methods, limitations, and future research areas.
- Synthesis of evidence regarding the application and development of 3D-printed teeth.
Main Results:
- 3D-printed teeth can overcome the limitations associated with natural teeth in research and training.
- Manufacturing involves 3D data, post-processing, and 3D printing to create prototypes.
- Key challenges include resin hardness and accurate replication of canal anatomy.
Conclusions:
- 3D-printed teeth show potential to replace natural teeth in ex vivo studies and endodontic training.
- Further development is required to establish standardized protocols and improve printing accuracy.
- Addressing current limitations will pave the way for 3D-printed teeth to become the gold standard.

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...
