Clinical diagnosis of oral submucous fibrosis with optical coherence tomography

A swept-source optical coherence tomography (SS-OCT) system with a specially designed probe is built for clinical scanning of oral submucous fibrosis (OSF) patients. By analysing 44 OSF cases of SS-OCT scanning results, two indicators, including epithelium (EP) thickness and standard deviation (SD) of A-mode scan intensity in the laminar propria (LP) layer, are found useful for real-time OSF diagnosis. Statistics show that sensitivity and specificity of LP SD can reach 84.1 and 95.5 %, respectively. Also, both sensitivity and specificity of EP thickness can reach 100 %.
