Theoretical Background to Automated Diagnosing of Oral Leukoplakia: A Preliminary Report

Abstract EN

Oral leukoplakia represents the most common oral potentially malignant disorder, so early diagnosis of leukoplakia is important.

The aim of this study is to propose an effective texture analysis algorithm for oral leukoplakia diagnosis.

Thirty-five patients affected by leukoplakia were included in this study.

Intraoral photography of normal oral mucosa and leukoplakia were taken and processed for texture analysis.

Two features of texture, run length matrix and co-occurrence matrix, were analyzed.

Difference was checked by ANOVA.

Factor analysis and classification by the artificial neural network were performed.

Results revealed easy possible differentiation leukoplakia from normal mucosa (p<0.05).

Neural network discrimination shows full leukoplakia recognition (sensitivity 100%) and specificity 97%.

This objective analysis in the neural network revealed that involving 3 textural features into optical analysis of the oral mucosa leads to proper diagnosis of leukoplakia.

Application of texture analysis for leukoplakia is a promising diagnostic method.
