Statistical analyses included one-way ANOVA and simple linear regression for color measurements, as well as one-way ANOVA, Shapiro-Wilk, Kruskal-Wallis, and Holm-Bonferroni tests for chemical composition. The results indicated a significant decrease in <i>L</i>* (<i>p</i> = 0.01) and <i>b</i>* (<i>p</i> = 0.03) values in G3. The highest mean values of <i>∆E*<sub>ab</sub></i> and Δ<i>E<sub>00</sub></i> (<i>p</i> ⩽ 0.05) exceeded PT and AT indicating good effectiveness. ATR-FTIR analysis revealed that certain phosphate bands in G3 remained unchanged compared to G1 and G2. Additionally, carbonate substitution at the A and B-positions was reduced, and the degree of mineralization increased compared to G2. XRD patterns showed diffraction peaks linked to hydroxyapatite crystals in all experimental groups. All treatments reduced crystallite size, and this effect was not reversed in G3. Thus, this study demonstrates that ERS achieved a superior whitening effect compared to HP, without altering the chemical composition or crystalline structure of human enamel. These findings suggest the potential of using ERS as a safer alternative to conventional peroxide-based whitening agents.</p>","PeriodicalId":14985,"journal":{"name":"Journal of Applied Biomaterials & Functional Materials","volume":"23 ","pages":"22808000251356939"},"PeriodicalIF":3.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144789239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
