Color change (\u0394E) was assessed on Days 1, 14, and 30 using a spectrophotometer based on the CIE Lab* system. Statistical analysis included One-Way ANOVA with Tukey post hoc tests for between-group comparisons, and Repeated Measures ANOVA with Bonferroni adjustment for within-group comparisons.ResultsAll groups showed significant differences in \u0394E values at each time point, except between the single and repeated KI groups on Day 1. The Group I exhibited the highest \u0394E values throughout the study, indicating the greatest discoloration, while Group III resulted in the lowest values. Over time, a progressive increase in discoloration was observed in Groups II, whereas partial color stability was maintained in Group III.ConclusionRepeated application of KI after SDF treatment can result in a higher reduction in tooth discoloration compared to a single-application. This protocol may enhance the clinical acceptability of SDF, especially for visible anterior teeth in pediatric patients.<\/jats:p>","DOI":"10.26650\/eor.20261845757","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T11:47:08Z","timestamp":1783338428000},"page":"304-310","update-policy":"https:\/\/doi.org\/10.26650\/iucrossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of a clinically feasible repeated potassium iodide application protocol on silver diamine fluoride\u2013induced discoloration"],"prefix":"10.26650","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6676-6952","authenticated-orcid":true,"given":"Samira","family":"Sadighbatha","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04waqzz56","id-type":"ROR","asserted-by":"publisher"},{"id":"https:\/\/www.isni.org\/000000011498685X","id-type":"ISNI","asserted-by":"publisher"}],"name":"Isfahan University of Medical Sciences","place":["Isfahan Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6840-5539","authenticated-orcid":true,"given":"Maryam","family":"Hajiahmadi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04waqzz56","id-type":"ROR","asserted-by":"publisher"},{"id":"https:\/\/www.isni.org\/000000011498685X","id-type":"ISNI","asserted-by":"publisher"}],"name":"Isfahan University of Medical Sciences","place":["Isfahan Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11192","published-online":{"date-parts":[[2026,7,6]]},"reference":[{"key":"1748403","unstructured":"Manton DJ.
