• Abstract This study aimed to investigate the clinical efficacy of using broadband white light (BWL) to observe morphologic appearance, narrow-band imaging (NBI) to observe intraepithelial microvasculature, and both BWL and NBI for the detection of high-grade dysplasia and carcinoma in oral leukoplakia. Among 317 patients (274 males and 43 females; aged 52.4 ± 10.7 years), the odds ratio (95% confidence interval) for detecting high-grade dysplasia and carcinomatous lesions based on morphologic appearances of BWL, and microvasculature patterns of NBI, were 39.12 (9.33–64.10), and 97.16 (38.19–247.21), respectively, which were significantly better than BWL ( p < 1 × 10−15 ). The sensitivity, specificity, positive and negative predictive values, and accuracy of use of traditional BWL classification, NBI classification, and combined BWL and NBI classification for detecting high-grade dysplasia and carcinomatous lesions were 96.30, 60.08, 33.12, 98.75, 66.25, 39.92, and 3.70%; 87.04, 93.54, 73.44, 97.23, and 92.43%; and 100.00, 60.08, 33.96, 100.00, and 66.88%, respectively. In conclusion, the diagnostic accuracy by NBI classification of oral leukoplakia based on the intraepithelial microvasculature patterns is significantly better than BWL indicating that NBI is a promising non-invasive tool in detecting high-grade dysplasia and carcinomatous lesions in oral leukoplakia.
