Of course. There are protocols for cleaning the CCD. Some DSLRs 
incorporate a barrier oin front of the CCD, in my case, CMOS. This aids 
cleaning by enabling removal of dust from a surface other than a CCD (or 
CMOS), and also providing a resting place for said dust that is not on 
the focal plain, and therefore not in focus. I have personally yet to see 
any problems with dust. Certainly I do not expect it to be as bad as the 
dust that accumulates in the corners of scanned negatives...
