    Area of Science:

    • Dentistry
    • Dental Materials Science
    • Clinical Research

    Background:

    • Extensive Amalgam Restorations (EAR) are common dental procedures.
    • Understanding factors influencing EAR fabrication time is crucial for efficient dental practice.
    • Previous studies have not comprehensively analyzed treatment times across different operators and retention methods.

    Purpose of the Study:

    • To analyze treatment times for Extensive Amalgam Restorations (EAR).
    • To identify factors influencing EAR fabrication duration, including operator, retention method, tooth location, and restoration extension.
    • To provide insights into the efficiency of EAR procedures in a clinical setting.

    Main Methods:

    • Analysis of treatment times from a longitudinal clinical trial involving 269 EARs on molars.

  • Data collected from three operators at the Dental School in Nijmegen.
  • Statistical analysis to determine the influence of operator, retention method, tooth side, and restoration extension on treatment time.

    • Main Results:

    • The mean total treatment time for EAR fabrication was 60 minutes.
    • Operator significantly influenced all treatment phases, causing a 26% difference in total treatment time.
    • Retention method, tooth side location, and restoration extension also showed significant influences on specific treatment phases.

    Conclusions:

    • Operator variability is a key factor affecting Extensive Amalgam Restoration (EAR) treatment times.
    • Retention methods, tooth location, and restoration size also impact procedural efficiency.
    • Treatment time data should be interpreted considering the quality of dental care provided.
