Computer-assisted image analysis of oral lichenoid reactions revealed significant color differences in lesions. This method correlates with clinical assessments, aiding diagnosis and decision-making.

Area of Science:

  • Oral pathology
  • Digital image analysis
  • Biomedical imaging

Background:

  • Oral lichenoid reactions (OLR) require accurate diagnostic methods.
  • Clinical assessment of OLR can be subjective.
  • Objective analysis tools can aid in diagnosis and treatment planning.

Purpose of the Study:

  • To evaluate the utility of computer-assisted image analysis for diagnosing oral lichenoid reactions.
  • To objectively quantify color variations in OLR lesions.
  • To correlate image analysis findings with clinical scoring.

Main Methods:

  • Color slides from 30 patients with histopathologically verified OLR were analyzed.
  • Image analysis focused on white hyperkeratotic and red inflamed areas.
  • Statistical analysis was performed using Red-Green-Blue (RGB), normalized red-green-blue (rgb), and Intensity-Hue-Saturation (IHS) color systems.

Main Results:

  • Statistically significant color differences were found in both hyperkeratotic and inflamed areas across all color systems.
  • Image analysis results showed a linear correlation with clinical scores for hyperkeratosis and inflammation.
  • Objective color measurements provided quantifiable data for lesion characterization.

Conclusions:

  • Computer-assisted image analysis offers an objective method for evaluating oral lichenoid reactions.
  • This technique can enhance diagnostic accuracy and clinical decision-making for OLR.
  • The correlation with clinical scores validates the reliability of the image analysis approach.
