The purpose of this study is to determine the impact of Potassium Iodide (KI) on the black/gray staining caused by Silver Diamine Fluoride (SDF) when applied to carious lesions.

Methods: The research study examined the use of SDF and SDF followed by KI (SDF+KI) on extracted permanent molars that have had caries induced on their surfaces and monitored for a period after application. To monitor the color changes, CIELAB color space readings – a color space defined by the International Commission on Illumination – was used. The system is composed of three values *L, *a, and *b, where the *L measures black to white across a span of 0 (black) to 100 (white). Measurements were taken at eight intervals between days 0 to 72.

Results: Upon conclusion, *L values were found to be significantly different between SDF and SDF+KI groups and from baseline. On average the SDF+KI group when compared to the SDF group was 9.47 units lighter.

Conclusion: The findings indicated the application of KI has the capability to reduce the black staining SDF alone causes, potentially making it a viable esthetic option for patients with anterior caries.
