Area of Science:

  • Occupational Health
  • Ergonomics
  • Dental Practice Management

Background:

  • Dental professionals face unique ergonomic challenges impacting their health and efficiency.
  • Standard ergonomic guidelines from ISO and FDI are not always feasible in clinical settings.
  • Understanding the practical application of ergonomic principles in dentistry is crucial.

Purpose of the Study:

  • To analyze the ergonomic work conditions in a Brazilian dental office using the Ergonomic Work Analysis (AET) method.
  • To identify spatial and layout constraints affecting dentists' adherence to recommended postures.
  • To evaluate the suitability of the AET method for understanding dental professionals' activities and work environment.

Main Methods:

  • Application of the Ergonomic Work Analysis (AET) method in a Brazilian dental setting.

  • Observation and documentation of five common dental treatments.
  • Analysis of action frequency, duration, and adopted working positions.
  • Identification of constraints and avoidance strategies employed by dentists.

    • Main Results:

    • Dentists rarely adopt the supine patient and 9 o'clock dentist positions recommended by ISO and FDI due to space limitations.
    • The AET method proved effective in analyzing dentists' activities and work environment.
    • The dental profession was characterized as stressful, perfectionist, and restrictive.
    • Time management emerged as a critical strategy for mitigating work-related tension.

    Conclusions:

    • Spatial and layout constraints significantly influence ergonomic practice in dental offices.
    • The AET method provides valuable insights into the ergonomic challenges and characteristics of dental work.
    • Effective time management is essential for dentists to cope with the demanding nature of their profession.
