Area of Science:

  • Forensic Science
  • Biomaterials Science
  • Dental Materials

Background:

  • Traditional personal identification methods can be lost or degraded.
  • Intraoral micro-identification discs present a novel, permanent solution for personal identification.
  • These discs are bonded to the buccal enamel of posterior teeth.

Purpose of the Study:

  • To describe the utilization and characteristics of intraoral micro-identification discs.
  • To explore the methods of fabrication, indicia application, and bonding techniques.
  • To assess the potential for in situ and post-removal identification.

Main Methods:

  • Microdiscs fabricated from plastic or stainless steel.
  • Indicia created via photoreduction, photochemical etching, or laser engraving.

Related Experiment Videos

  • Bonding to enamel using conventional etching and composite resin techniques.
  • Protective covering with composite material to prevent salivary degradation.

    • Main Results:

    • Indicia can be read with microscopes or handheld magnifiers.
    • Computerization aids in database access and reduces data on discs.
    • Discs can be attached to maxillary first permanent molars or second primary molars.

    Conclusions:

    • Intraoral micro-identification discs provide a permanent and secure method for personal identification.
    • Standardization of indicia and design is crucial for acceptance.
    • This technology enhances patient safety and forensic identification capabilities.
