Jordan28 participantsStarted 2018-12-01

Plain-language summary

The aims of this trial were to assess the effect of changing 0.019X0.025-inch SS working archwire monthly on the rate of space closure, to compare the frictional resistance of unchanged and new working archwires in-vitro, and to assess its effect on the rate of space closure, to record the amount of ion concentration in the saliva before orthodontic treatment, before space closure and one month after space closure.
