Abstract

Dental caries is a prevalent global oral health issue, necessitating effective preventive and treatment strategies. Silver diamine fluoride has emerged as a valuable tool for arresting carious lesions, but its drawback of causing permanent black staining raises concerns. This study explores the potential of potassium iodide to mitigate silver diamine fluoride -induced staining through repeated applications at different intervals. Sixty carious permanent teeth were divided into three groups: silver diamine fluoride alone, silver diamine fluoride with daily potassium iodide application, and silver diamine fluoride with weekly potassium iodide application. Color assessments were conducted using mean grey values at baseline, immediately post-application, and at 2 and 4 weeks. Results demonstrated that potassium iodide significantly reduced black staining when applied immediately after silver diamine fluoride. Daily potassium iodide application yielded the whitest color, surpassing weekly application. The findings suggest that integrating potassium iodide with silver diamine fluoride, particularly through daily application, offers a promising approach to minimize staining associated with silver diamine fluoride treatment, enhancing its acceptability and clinical utility.
