Effects of etch-and-rinse and self-etch adhesives on dentin MMP-2 and MMP-9.

abstract：:The presence and kinetics of bone-resorbing activity in periapical lesions were studied with a rat model system. Lesions were found to expand most rapidly between induction on day 0 and day 15 ("active phase"), with enlargement occurring at a slower rate thereafter (days 20 and 30, "chronic phase"), as assessed by mea...
