Summary
This study presents a simple denture marking technique using embossed country codes to identify nationality. This method ensures undegradable identification for denture wearers.
Area of Science:
- Biomaterials Science
- Forensic Dentistry
- Dental Prosthetics
Background:
- Accurate identification of individuals is crucial in various forensic and medical scenarios.
- Denture wearers may require identification, especially in cases of emergencies or unidentified remains.
- Current denture identification methods can be degraded or difficult to implement.
Observation:
- A novel technique involves embedding an embossed metal plate with country and clinic codes within the denture base.
- The plate, made from a titanium-aluminum-niobium (Ti-6Al-7Nb) alloy, is integrated into the metal framework before acrylic resin fabrication.
- The embossed markings are clearly visible through the denture base material.
Findings:
- The casting process successfully reproduced the embossed identification marks on the metal framework.
- The integrated metal plate provides a durable and permanent method for denture identification.
- The technique allows for straightforward determination of the denture wearer's nationality based on the country code.
Implications:
- This method offers a simple, cost-effective, and undegradable solution for denture identification.
- It can significantly aid in identifying denture wearers in forensic investigations and disaster victim identification.
- The technique enhances the traceability and personal identification associated with prosthetic devices.

Teeth
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 and...

Tooth Anatomy
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 grinding food.
