Pig toothbrush bristles imported from China were studied with a scanning electron microscope (model JSM U III manufactured by Japan Electron Optics Laboratory Co., Ltd.) The bristles were coated with carbon and gold, and observed under an accelerating voltage of 10 Kv. The surface of the bristles was not glassy. Under weak magnification the surface looked like bark or elephant skin, but under strong magnification the surface was seen to be scaly. Some abnormal shapes such as crevices or projections were also observed on the surface of the bristles. The form of the tips was varied, and bristles having an ideal tip were rare. This phenomenon is also seen in nylon bristles.
