Abstract:

Castability plays an important role in selection of an alloy for cast dental restorations. This study was conducted to assess the effect of recasting of nickel-chromium alloy on its castability. Different percentage combinations of new and once casted alloy were used to produce a total of twentyfive cast samples using modified Whitlock's method and castings obtained from new alloy were used as control group. Castability value was obtained by using Whitlock's formula. Results were analyzed using student 't' test. There is no statistical difference between the castability value of the new alloy and the recasted alloy (confidence level 95%). Within the limitations of the study it is concluded that the castability value will not be affected by recasting the nickel-chromium alloy. Complete castings of any metal restoration are mandatory and to know the completeness of castings of any alloy, castability test is of prime importance.
