Aim:The aim of the study was to evaluate the staining effect of potassium iodide and silver diamine fluoride
Methods:Sixteen carious primary teeth were collected and stored in saline. Caries was excavated by using a
sharp spoon excavator. The teeth received SDF+KI. Color changes (ΔE) were measured using a
spectrophotometer at the following time intervals: before solutionapplication (baseline) and immediately
after application, then 72 hours after application
Results:showed that within 38% SDI + KI group, there was no statistically significant difference either in
ΔEmean values between different time intervals (P=0.2300).
Conclusions:silver Diamine fluoride and KI showed minimal color changes over the 72 hours.
