A Study of the Surface Roughness of Tongue Cancer and Leukoplakia Using a Non-contact Three-dimensional Curved Shape Measuring System.

Measurement of lubricating properties in a tribosystem with different surface roughness

“…However, as shown by all roughness indices and three-dimensional images, the surface of P4 was the most structured. The obtained sRa parameters of P5, P7 and P8 were in the same magnitude order as the tongue ones (Nagaoka et al, 2001;Uemori, Kakinoki, Karaki, & Kakigawa, in press).…”

Inhomogeneity of stiffness and density of the extracellular matrix within the leukoplakia of human oral mucosa as potential physicochemical factors leading to carcinogenesis

“…It does not predict premalignancy [ 26 , 54 ]. In a previous study, a noncontact, three-dimensional curved shape measurement showed high surface roughness of squamous cell carcinoma and leukoplakia that affected the tongue [47] . This inhomogeneity in surface roughness, indicative of abnormal epithelial hyperplasia, is in strong agreement with our data indicating rheological inhomogeneity in leukoplakia and in tested samples of squamous cell carcinoma tissues.…”
