Potassium Iodide: The Solution to Silver Diamine Fluoride Discoloration?
Objectives: Silver diamine fluoride (SDF) is increasingly recognized as a cost-effective, easy-to-use alternative to reduce sensitization and arrest caries. However, SDF causes black staining of caries. Potassium iodide (KI) treatment with SDF may decrease or lessen the staining but the effectiveness of KI on staining has not been investigated. This study examined SDF/KI with various restorative materials, on carious and sound tooth structure.
Methods: Ten groups of teeth were treated to evaluate the effect of KI and SDF treatment. Visual examination and color measurements were used to evaluate color changes among the groups. Two groups (N= 8) had existing caries while the remaining groups had minimal decay (N= 32). One control tooth was prepared for each group using the same procedure without the use of SDF or KI (N= 5).
Results: A total of 40 teeth were treated with silver diamine fluoride. The comprehensive experiment was over a period of four weeks with each tooth photographed and findings recorded weekly. A total of 10 groups showed changes reflecting the use of SDF and KI. Teeth treated with only SDF were representative of our controls and expected to darken over time, as it is the characteristic of SDF treatments. All teeth treated with KI showed minimal to no changes regardless of the type of restorative material used. The color changes with the materials used were calculated and reported by the Nix pro color sensor. Our data indicates groups that underwent SDF treatment alone showed a noticeable decrease in ΔL value when compared with groups that had KI added. The staining varied among the groups due to the different procedures and materials that were implemented; however, all of the teeth that received the KI showed a more natural and esthetically pleasing shade of color when compared with teeth that received only the SDF.
Conclusions: Our treatments of teeth with SDF with KI significantly reduce the discoloration. The effectiveness of this combination treatment should be clinically substantiated. If caries can be arrested or mitigated with this 2-step non- invasive treatment, a low-cost treatment may be more acceptable and practical for areas without full dental operatories, hospital or bedridden patients, or lower-cost pediatrics.
