    Area of Science:

    • Dental Public Health
    • Health Workforce Planning
    • Epidemiological Modeling

    Background:

    • Accurate forecasting of healthcare professional supply is crucial for effective health system planning.
    • Understanding the dynamics of the dental workforce, including supply, demand, and demographic shifts, is essential for Australia.
    • Previous analyses may not have fully captured the complexities of dental manpower fluctuations.

    Purpose of the Study:

    • To project the supply of dentists in Australia up to 1991 using a transitional matrix model.
    • To assess the impact of key variables such as baseline data, graduate recruitment, and international migration on dental supply projections.
    • To analyze the changing age distribution and wastage rates within the Australian dental workforce.

    Main Methods:

    • A transitional matrix model was employed to analyze projected dental supply.
    • Sensitivity analyses were conducted to evaluate the influence of different assumptions on recruitment and migration.
    • Data on the age distribution and wastage rates of dentists were collected and analyzed.

    Main Results:

    • The study demonstrated the critical importance of selecting appropriate baseline data for dental stock.
    • Projections were highly sensitive to assumptions regarding the recruitment of Australian dental graduates.
    • The influx of foreign-trained dentists significantly impacted the projected supply.
    • Analysis revealed shifts in the age distribution of Australian dentists and identified wastage rates.

    Conclusions:

    • Transitional matrix modeling is a valuable tool for understanding and projecting dental manpower.
    • Future dental workforce planning must carefully consider baseline data accuracy, graduate intake, and international recruitment.
    • Further refinement of the transitional matrix model is recommended for more robust dental manpower studies.
