Abstract

Air particle abrasion (APA) is a common surface preparation method in dentistry, particularly for improving bond strength to dentin. This review evaluates the influence of APA on dentin adhesion. : A systematic literature search from 2018 to 2023 was conducted according to PRISMA-ScR guidelines. Articles investigating the effects of APA on dentin adhesion using different particle types, sizes and adhesive systems were included. Data extraction included particle size, air pressure, outcomes tested and failure modes. : Fourteen primary studies met the criteria. Bioactive glass showed higher bond strength and more cohesive failures than alumina. Alumina particles (50 μm) bonded effectively in etch-and-rinse adhesive systems but failed more often in self-etch systems. Silica-modified alumina and mixed abrasive systems showed improvements in bonding performance. Optimal APA parameters were identified as 50 μm particle size, 60 psi (4 bar) air pressure and 5 s exposure time. Longer exposure times provided no additional benefit. Self-etch systems showed reduced bond strength compared to etch-and-rinse systems. : This review looks at how particle type, size and air pressure affect dentin adhesion. Bioactive glass is a superior material due to its bond strength and reduced cytotoxicity. The optimal APA parameters are 50 μm particle size, 60 psi and 5 s. Etch-and-rinse systems are recommended for optimal adhesion. Further research is required on APA protocols and long-term durability.
