Literature review shows aluminum oxide air abrasion improves bonding in enamel and dentin, suggesting better protocols are needed.
Conclusions: When applied with optimized parameters, aluminum oxide abrasion improves bonding to enamel and dentin, is particularly useful in etch-and-rinse protocols and composite repair, and should be avoided on dentin with self-etch adhesives. Further in vivo studies are needed to clarify long-term performance.
