NCT06641011

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Retention Rate of Fissure Sealants with regard to the type of sealant and AgF pretreatment applied.

    The US Public Health Service criteria (secondary caries, anatomical form, marginal adaptation, marginal discoloration) will be used for clinical evaluation of restorations. The restorations will be evaluated at baseline and 1., 6., 12., 18., 24. months. Intra-oral photos will be taken directly after treatment and at control appointments to evaluate discoloration and seconder caries under magnification.

    From enrollment to the end of treatment: 14 months (from July 2023 to October 2024). The first-year outcomes are planned for October 2025, and the second-year outcomes are planned for October 2026.

Secondary Outcomes (4)

  • Incidence of Caries

    From enrollment to the end of treatment: 14 months (from July 2023 to October 2024). The first-year outcomes are planned for October 2025, and the second-year outcomes are planned for October 2026.

  • Marginal Integrity of Sealants

    From enrollment to the end of treatment: 14 months (from July 2023 to October 2024). The first-year outcomes are planned for October 2025, and the second-year outcomes are planned for October 2026.

  • Tooth Sensitivity

    From enrollment to the end of treatment: 14 months (from July 2023 to October 2024). The first-year outcomes are planned for October 2025, and the second-year outcomes are planned for October 2026.

  • Color and esthetic Changes

    From enrollment to the end of treatment: 14 months (from July 2023 to October 2024). The first-year outcomes are planned for October 2025, and the second-year outcomes are planned for October 2026.
