Abstract
Frictional force and coefficient of friction between stainless steel brackets and arch wires were measured in both dry and saliva conditions at various loads and velocities. The results showed no effect of velocity on friction in most cases. Human saliva had effects of increasing frictional force and coefficients of friction. The coefficients of friction are 0.011-0.013 for dry condition and 0.026-0.027 for saliva condition.
Frictional force and coefficients of friction between a stainless steel arch wire and ligatures were tested as well in both dry and saliva conditions. In dry condition, elastomeric ligature material exhibited larger frictional force than stainless steel ligature material at low normal forces. In saliva condition, stainless steel ligature material produced greater frictional force than elastomeric ligature material at high normal force. Human saliva, again, increased both frictional force and coefficients of friction in both types of ligature materials.
