Biofluorescence imaging as a valid alternative for dental calculus detection

Area of Science:

• Dental diagnostics
• Periodontology
• Biophotonics

Background:

• Dental calculus is a primary cause of periodontal disease.
• Accurate detection of dental calculus is crucial for effective treatment.
• Conventional methods include visual-tactile examination.

Purpose of the Study:

• To evaluate the detectability of dental calculus using quantitative biofluorescence imaging (BFI).
• To compare the diagnostic accuracy of BFI with white-light imaging (WLI) and visual-tactile (VT) examination.
• To assess BFI's ability to quantify calculus accumulation.

Main Methods:

• Ten adults underwent examination of 285 tooth surfaces.
• Sites were imaged using WLI and BFI with a specialized intraoral camera.
• Visual-tactile examination served as the reference standard; color difference (ΔE) and red biofluorescence intensity (ΔR) were measured.

Main Results:

• BFI demonstrated significantly higher ΔE values than WLI, correlating with calculus severity.
• Red biofluorescence intensity (ΔR) increased with calculus accumulation.
• Combined WLI + BFI improved sensitivity (0.84 vs. 0.61) and specificity (1.00 vs. 0.91) compared to WLI alone.

Conclusions:

• Biofluorescence imaging provides more distinct detection of dental calculus than WLI.
• BFI enhances diagnostic accuracy by enabling quantitative assessment of calculus.
• This technology holds promise for improved diagnosis and management of periodontal disease.
