Untrained operators showed low efficacy in root scaling with both curettes and power-driven instruments. With training, effectiveness improved, but power-driven systems were less effective on complex root anatomy.

Area of Science:

  • Periodontology
  • Dental instrument efficacy
  • Skill acquisition in dentistry

Background:

  • Assessing the learning curve for dental scaling instruments in untrained operators.
  • Comparing the effectiveness of manual curettes versus power-driven systems for subgingival scaling.
  • Evaluating operator skill development over a 10-week training program.

Purpose of the Study:

  • To evaluate the learning effectiveness of untrained operators using curettes (GRA) and power-driven instruments (PP) for subgingival scaling.
  • To compare the efficiency and effectiveness of these two scaling methods.
  • To analyze the impact of root anatomy complexity and accessibility on scaling outcomes.

Main Methods:

  • A dummy-head trial involving two groups of 11 untrained operators each.

  • Six 2-hour training lessons over 10 weeks.
  • Assessment of debrided root area percentage using image analysis and measurement of scaling time.
  • Evaluation of performance on teeth with varying root complexity and accessibility.

    • Main Results:

    • Initial scaling efficacy was 63.1% for GRA and 52.3% for PP.
    • Operators reached a plateau by weeks 9-11, with GRA at 84.7% and PP at 81.3%.
    • Scaling time was comparable between groups, but PP was less effective on complex/inaccessible root surfaces.

    Conclusions:

    • Untrained operators achieved low root surface debridement efficacy regardless of instrument type.
    • Systematic training enabled comparable learning curves for power-driven systems and hand instruments.
    • Power-driven systems demonstrated significantly lower effectiveness on teeth with complex root anatomy and difficult access.
