Effect of contact load upon attrition-corrosion of human dental enamel

For the acidic lubricants, the increase in enamel loss with increasing load was insignificant. However, for the distilled water lubricant, there was a significant increase in the wear loss with load. The associated wear mechanisms were shaving of the softened layer with acidic lubricants and delamination with distilled water. The greater friction and wear associated with the delamination mechanism resulted in a significantly higher wear loss with distilled water than with acidic lubricants.
