Assessing the Use of Radiographs Alone to Determine Air Force Dental Readiness Classification

Area of Science:

• Military Health
• Dental Diagnostics
• Radiographic Interpretation

Background:

• The Air Force Dental Service ensures airmen's dental readiness for global operations.
• Innovative dental care delivery models are being explored, including radiography as a primary assessment tool.
• Focus is on identifying nondeployable conditions and periodontal health using radiographs.

Purpose of the Study:

• To evaluate the diagnostic performance of using only radiographs for dental assessments.
• To compare radiograph-only assessments against a gold standard including clinical examinations.
• To determine the feasibility of radiography as the sole method for assessing dental readiness and periodontal health.

Main Methods:

• Dental providers re-evaluated de-identified records using only radiographs.
• Assessments included Dental Readiness Classification (DRC), caries counts, and Periodontal Screening and Recording (PSR) scores.
• Diagnostic performance (sensitivity, specificity) was calculated, and provider confidence was assessed.

Main Results:

• High specificity (>70%) for ruling out certain conditions (DRC 3).
• Low sensitivity (as low as 8%) for positively identifying DRC 3 conditions and periodontal issues via radiographs.
• Low agreement (<33%) for PSR scores and low provider confidence in radiograph-only assessments.

Conclusions:

• Sole reliance on radiographs is cautioned against for assessing U.S. Air Force personnel dental health.
• Inability to reliably identify critical conditions (DRC 3) poses risks to operational readiness.
• Combined radiographic and clinical examinations remain essential for comprehensive dental assessments.
