Danish dentists and dental students demonstrate limited understanding of basic statistical terms like standard deviation (SD) and p-values. This knowledge gap hinders their ability to critically evaluate statistical analyses in their practice.

Area of Science:

  • Dental Statistics
  • Evidence-Based Dentistry

Background:

  • Statistical literacy is crucial for interpreting research in dentistry.
  • Many dental professionals may lack the necessary skills to critically assess statistical data.

Purpose of the Study:

  • To evaluate the statistical knowledge of Danish dentists and dental students.
  • To assess understanding of fundamental statistical expressions relevant to dental research.

Main Methods:

  • A multiple-choice test on elementary statistical concepts was administered to a random sample of Danish dentists.
  • The same test was given to dental students after their final statistics lecture.

Main Results:

  • Only 52% of dentists (129/250) completed the statistical knowledge test.

  • The median correct answers were 2.2 for dentists and 3.4 for dental students.
  • A significant portion of dentists (35%) did not consider statistical knowledge a high priority.

    • Conclusions:

    • Most dentists possess insufficient statistical knowledge to critically interpret research findings.
    • Dental students show a slightly better, but still limited, grasp of statistical concepts.
    • There is a need to improve statistical education in dentistry to support evidence-based practice.
