Abstract

Background: Microabrasion changes the enamel surface, lowering the binding strength of composites. Numerous surface treatments were applied on the enamel surface to increase the binding strength of the composites. The purpose of this study was to determine the effect of non-thermal atmospheric plasma (NTAP), grape seed extract (GSE), and bromelain affected the composite/’s shear bond strength (SBS) after bleaching and microabrasion. Materials and Procedures: Eighty extracted human maxillary anterior teeth were used in this study. These teeth were distributed into two groups. Groups 1 and 2 were bleaching and microabrasion, accordingly. Tooth whitening methods including bleaching and, and were further separated into four subgroups (n = 10) depending on the type of surface treatment used. No surface treatment in Group A, bromelain in Group B, GSE in Group C, and NTAP in Group D. The labial surface was coated with composite resin and placed in artificial saliva for 24 h. All of the samples were submitted to SBS testing. Statistical Analysis: Two-way analysis of variance and post hoc Tukey’s test were used during the analysis, with P 0.05 regarded statistically significant. The highest bond strength (35.4 Mpa) was found in Group 1D, whereas the least bond strength values were found in Group 1A. (15.7 Mpa). With the exception of Groups 1A and 1B (P = 0.972), there had been a significant difference between the bleaching groups. There is also a significant difference between Group 2A and 2D (P = 0.0001), Group 2B and 2D (P = 0.0010), and Group 2C and 2D (P = 0.0001) in the microabrasion group. Conclusions: After bleaching, the SBS of composite resin was significantly improved using NTAP and GSE. The use of NTAP on microabraded surfaces improved composite resin bond strength.
