Abstract: Friction and wear tests of natural tooth in sliding against TA2 titanium ball are carried out. Friction and wear behaviour of different layer surfaces of the natural tooth are performed by microscopic examination. Results show that outer enamel of corona dentis has an excellent tribological resistance, and mixed layer between enamel and dentine zone has better abrasive resistance than dentine zone.
