Abstract :
In order to assess and compare the impact of different antioxidants on the shear bond strength of composite resin to bleached enamel, this study aimed to do a systematic review of the literature and meta-analysis. Bleaching is considered as the conservative and less invasive option for treating discolored tooth. The shear bond strength of composite resin to bleached enamel may be negatively impacted by bleaching byproducts. From January 2017 to July 2023, two reviewers separately searched the Cochrane, PubMed, and Google Scholar databases for relevant material using MeSH words, text words, and Boolean operators.. evaluation of the risk of bias for in vitro research conducted using the Quality Assessment Tool for In Vitro Studies (QUIN Tool). RevMan 5.4 was used to apply the meta-analyses using the random effects model (RevMan 5.4, The Nordic Cochrane Centre, Copenhagen). A Q test was used to evaluate heterogeneity, and I2 statistics were used to quantify it. Out of the 60 studies that were initially recovered, eight were chosen for a systematic review, and eight of those were able to be included in the meta-analysis. With a normalized mean difference of 6.05 (95% CI = 4.97 to 7.12; Z value = 10.99), grape seed extract had the highest shear bond strength values of all ten antioxidants.
Antioxidant therapy is thought to be a suitable way to increase the shear bond strength of bleached teeth. Among all the antioxidants grape seed extract is the most effective antioxidant in restoring the composite resin's shear bond strength to bleached enamel.
