Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Surface Science

Background:

  • Restorative dental materials are crucial for repairing and replacing damaged or missing teeth.
  • This paper focuses on materials used for the crown portion of teeth, excluding auxiliary, denture, and root canal materials.

Purpose of the Study:

  • To present progress and recent research on key restorative dental materials.
  • To highlight the application of Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) in characterizing these materials.

Main Methods:

  • Utilized Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) for material characterization.
  • Discussed replication methods for in situ SEM studies of restorative materials.
  • Applied SEM/EDS for analyzing changes and degradation in materials during clinical use.

Main Results:

  • SEM/EDS techniques were applied to dental amalgam, bonding agents, composites, cements, casting alloys, and ceramic-metal/ceramic materials.
  • Replication methods enable in situ SEM analysis of restorative materials.
  • SEM/EDS effectively characterizes material degradation and changes over time in clinical settings.

Conclusions:

  • SEM and EDS are powerful tools for the characterization and analysis of restorative dental materials.
  • Understanding material degradation through SEM/EDS is vital for improving clinical longevity and performance.
  • Further research utilizing these techniques can advance the development of novel dental restorative materials.
