Figure 3.

Clinical, OCT & histology images. Clinical (A) and OCT (B) images were captured for all the subjects and the biopsy tissues collected (wherever indicated) were assessed by histopathology (C). Histology images were taken at 100× resolution (scale bar = 100 µm) using Nikon DSFi2 and NIS elements D4 20.0. The non-dysplastic lesions shown were histologically diagnosed with lichen planus, pyogenic granuloma, and hyperkeratosis. Normal buccal mucosa images were taken from healthy volunteer without any habit history. Representative images of all dysplastic grades and a buccal oral squamous cell carcinoma (OSCC) are also depicted.
