Samples were immersed twice daily for 30 sec in their respective solutions and stored in artificial saliva at 37°C between immersions for 21 days. Force measurements were recorded at baseline (Day 0) and on Days 1, 7, 14, and 21 using a digital force gauge. Data normality was assessed using the Shapiro-Wilk test. As the data were not normally distributed, the Kruskal-Wallis test followed by the Mann-Whitney U test was applied, with statistical significance set at <i>P</i> < 0.05.</p><p><strong>Results: </strong>Both mouthrinses produced a progressive reduction in force over time, with the greatest force decay occurring within the first 24 hours, followed by a more gradual decline up to 21 days. However, elastomeric chains immersed in Pepsodent Daun Sirih<sup>®</sup> consistently retained higher residual force than those immersed in Listerine<sup>®</sup> Zero at all observation periods, indicating a slower rate of force degradation.</p><p><strong>Conclusion: </strong>Pepsodent Daun Sirih<sup>®</sup> demonstrated a lower degree of force decay and maintained significantly higher residual force compared with Listerine<sup>®</sup> Zero throughout the observation period. These findings suggest that Pepsodent Daun Sirih<sup>®</sup> may be a more suitable alcohol-free mouthrinse for preserving orthodontic force during treatment.</p>","PeriodicalId":16604,"journal":{"name":"Journal of Orthodontic Science","volume":"15 ","pages":"16"},"PeriodicalIF":0.0,"publicationDate":"2026-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13354118/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148421821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
