• Conditions: Children with dental caries

• Registration Number: CTRI/2025/06/088042
• Lead Sponsor: Dr Julita Joseph

Brief Summary

This is a comparative study done to evaluate the amount of silver ions in carious lesions in tooth treated with silver diamine fluoride, silver diamine fluoride followed by potassium iodide and silver diamine fluoride with light curing for 20 seconds. SDF increases the resistance to acid dissolution andincreases mineral density and hardness. A rich mineralised layer can be foundon the surface of arrested carious lesions. It also exhibits controlof caries infection, simplicity of use, affordability, minimal requirement fortraining and it is a minimally invasive treatment. Potassium iodide(KI) is a salt that generates white or transparent hexahedral crystals.Applying KI with SDF creates a silver iodide precipitate that is yellow,insoluble and does not cause black staining on the tooth. It is seen that curingof SDF using light emitting diode (LED) light curing increased precipitation ofsilver ions in the infected dentine layer of the carious lesion.
