About this study

Official title: 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.

Read the detailed description

Teeth will be randomized in a parallel design based on the application of restoration time (immediate or one week later), sealant material type (resin or glass ionomer), and for immediate applications, the condition of silver fluoride before restoration (dried with cotton or rinsed gently). A total of 216 permanent molars will be included in the study.

Randomization of molar teeth into six groups according to the restoration time, dental restorative material type, and conditions:

Being tested
Immediate restoration (resin- based) after blot-drying silver fluoride application, Immediate restoration (GI- based) after blot-drying silver fluoride application, Immediate restoration (Resin based) after rinsing silver fluoride application, Immediate restoration (GIC) after rinsing silver fluoride application, Resin based fissure sealant restoration one week after silver fluoride (AgF) application

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 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)
  1. Incidence of Caries

    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

    Measured: 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.

  2. Marginal Integrity of Sealants

    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

    Measured: 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.

  3. Tooth Sensitivity

    The Schiff Cold Air Sensitivity Scale (SCASS) will be used at 1, 6, 12, 18 and 24 months follow-ups to assess the presence of hypersensitivity in affected teeth by applying an air blast perpendicularly on the occlusal surface of the tooth for 1 second at a distance of 1 cm.

    The patient's response will be recorded according to the following scores:

    0 = subject does not respond to the stimulus;

    1. = subject does not respond to the stimulus but considers the stimulus to be painful;
    2. = subject responds to the air stimulus and moves away from the stimulus; and 3 = subject responds to the air stimulus, moves away from the stimulus, and requests an immediate cessation of the stimulus

    Measured: 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.

  4. Color and esthetic Changes

    Discoloration of the restorations will be recorded at 1, 6, 12, 18, and 24 months follow-ups.

    Measured: 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.
