Dental students replaced nearly 1,000 amalgam surfaces over 15 weeks. Marginal breakdown and decay were the main reasons for replacing these dental fillings.

Area of Science:

  • Dental materials science
  • Clinical dentistry
  • Restorative dentistry

Background:

  • Amalgam restorations are widely used in dentistry.
  • Understanding reasons for amalgam replacement is crucial for clinical practice and material development.
  • Student-led procedures offer insights into common restorative challenges.

Purpose of the Study:

  • To analyze the reasons and extent of amalgam restoration replacement by dental students.
  • To identify the most frequent causes necessitating amalgam removal in a clinical setting.
  • To document the number of amalgam surfaces and teeth addressed during the study period.

Main Methods:

  • A 15-week observational study involving six faculty supervisors and clinical dental students.
  • Systematic recording of tooth numbers, replaced amalgam surfaces, and reasons for replacement.

Related Experiment Videos

  • Data collection on instructor supervision and student performance.

    • Main Results:

    • A total of 956 amalgam surfaces were removed from 436 teeth.
    • The primary indications for replacement were marginal breakdown (69%) and secondary caries (33%).
    • Data on specific teeth and instructors were also collected and analyzed.

    Conclusions:

    • Marginal breakdown and caries are the predominant factors driving amalgam restoration replacement by dental students.
    • These findings highlight the importance of monitoring restoration integrity and early caries detection in dental education.
    • The study provides valuable data on the practical challenges encountered in amalgam replacement procedures.
