Effect of Non-Thermal Atmospheric Plasma on Micro-Tensile Bond Strength at Adhesive/Dentin Interface: A Systematic Review

“…First, it may have stiffening effect on the hybrid layer, as confirmed by the results of short-term evaluations of the nano-hardness and Young’s modulus [ 34 ], and it can apparently inhibit the matrix metalloproteinase (MMPs) enzymatic activity in the ER mode. [ 35 ] NTAP application resulted in the formation of a thicker hybrid layer in the ER mode, as observed in SEM assessment [ 37 , 43 ]. In addition, the micro-Raman spectroscopy analysis indicated better penetration of the adhesive resin into the hybrid layer.…”

“…Only studies in which the μTBS test was applied were included in this systematic review as the μTBS test is a versatile and effective method for evaluating the resin–dentin bond strength [ 49 , 50 , 51 ], that may correlate with clinical outcomes better than other bond strength tests [ 52 ]. NTAP application had a significant positive effect on the resin–dentin μTBS [ 33 , 34 , 35 , 36 , 37 , 38 , 40 , 41 , 42 , 43 , 44 ]. While in two studies [ 27 , 39 ], NTAP application resulted in only a short-term material-dependent positive effect that was not stable after long-term aging.…”

“…Within the limitations of this systematic review, NTAP application could enhance resin–dentin μTBS of ER adhesives or UAs applied in the ER mode. The NTAP effect could be a result of the enhancement in the quality of the hybrid layer formed [ 33 , 37 , 38 , 43 ] and the inhibition of the MMPs enzymatic activity [ 35 ]. In the ER mode, NTAP can be considered an effective drying method of acid-etched dentin, and the rewetting step after NTAP seems to be unnecessary.…”

“…[28,[42][43][44] Upon the qualitative assessment of resin-dentin interfacial morphology using SEM, in the case of the SE mode, no significant difference was detected between NTAP-treated and non-treated groups [27,35,41]. However, in the ER mode, the resin tags formed following NTAP application were longer, well-defined and more abundant compared to non-treated groups [35,37,38,42,43], which was in contrast to the results obtained by Hirata et al [39] However, the interpretation of adhesive penetration (resin tags) into dentin is controversial. [53] Thus, it cannot be used alone to explain the positive impact of NTAP on resin-dentin µTBS.…”
