Scanning with a scanner or enlarging with an enlarger is the same thing: make a positive from a negative.
Um...if you are trying to deal with removing scratches then scanning versus enlarger prints is two entirely different problems.
I'm guessing something is being lost in translation here so I'm gonna let it go.
As for the OP, scratched negatives suck but be glad you do have the digital option to correct them. The healing brush is probably the best tool to deal with it but if you want to try a potentially easier solution, check out the content aware fill features in PS. I think they started getting pretty good in CS5. If your version is earlier then you are stuck with healing brush.
