A scanning electron microscope study of the surface features of porcine oral mucosa.

The surface features of porcine oral mucosa were examined in the scanning electron microscope. A large number of regularly occurring surface features were recorded and some of these appeared to be unique to particular areas of oral mucosa. It is suggested that an objective investigation of these apparently area-specific surface features may show whether they can be used as a new accurate method of identifying types of oral mucosa.
