This Study Aims to Evaluate the Effect of Rinsing Off or Blot-drying Silver Fluoride on the Retention of Subsequently-applied Resin- and Glass Ionomer-based Fissure Sealants in Permanent Molars Affected by Molar-Incisor Hypomineralization.

The aim of this study is three-fold: 1. To evaluate the clinical performance of glass ionomer fissure sealants and resin fissure sealants when placed immediately after or one week following the application of silver fluoride on permanent molars affected by Molar-Incisor Hypomineralization in high caries-risk children. 2. To compare the effects of rinsing off the silver fluoride or not rinsing it off (blot-drying with cotton pellet) on sealant retention when the sealant is placed immediately after silver fluoride application, and 3. To measure the desensitizing effect of fissure sealant application following silver fluoride treatment on hypersensitive MIH molars.
