Table 3:<b> </b>Independent t-test for comparing the effect of two ageing conditions on frictional forces using Damon or Pactive brackets with two wire gauges. Regarding Damon brackets, the acid challenge elicited significantly higher static and kinetic frictional forces than water storage when these brackets coupled with round CuNiTi wires. For Pactive brackets, exposure to the acidic attack resulted in significantly higher kinetic frictional forces than water storage, with both wire gauges.
