  • Arrest of dental caries assessed based on a clinical oral examination [ Time Frame: Two years ]
    For any untreated dental caries on teeth at baseline treated with SDF/FV or Glass ionomer/FV to arrest (control) the infection, what is the proportion of treated (arrested) caries that stayed arrested

Descriptive Information
Brief Title  ICMJE Comparative Effectiveness of Treatments to Prevent Dental Caries
Official Title  ICMJE Comparative Effectiveness of Treatments to Prevent Dental Caries Given to Rural Children in School-based Settings: Protocol for a Cluster Randomized Controlled Trial
Brief Summary Dental caries (tooth decay) is the most prevalent childhood disease in the world. Multiple interventions are available to treat and prevent caries. The aim of the proposed study is to compare the benefit of silver diamine fluoride (SDF) and fluoride varnish versus fluoride varnish and glass ionomer sealants. This study is a five-year, cluster randomized, pragmatic controlled trial conducted in public elementary schools in New Hampshire.
Detailed Description

Dental caries is the most prevalent childhood disease in the world and can lead to infection, pain, reduced quality of life, and negative educational outcomes. Multiple prevention agents are available to arrest and prevent dental caries, however little is known of the comparative effectiveness of combined treatments in pragmatic settings. The aim of the presented study is to compare the benefit of silver diamine fluoride and fluoride varnish versus fluoride varnish and glass ionomer therapeutic sealants in the arrest and prevention of dental caries.

This is a longitudinal, pragmatic, cluster randomized, single-blind, non-inferiority trial to be conducted in low-income children enrolled in public elementary schools in New Hampshire from 2017-2023. The primary objective is to assess the non-inferiority of alternative agents in the arrest and prevention of dental caries. Caries arrest will be evaluated after two years, and caries prevention will be assessed at the completion of the study. Data analysis will follow intent to treat, and statistical analyses will be conducted using a two-sided significance level of 0.05.

Notably, the standard of care for dental caries is office-based surgery, which presents multiple barriers to care including cost, fear, and geographic isolation. The simplicity and affordability of silver diamine fluoride may be a viable alternative for the arrest and prevention of dental caries in high-risk children.

Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
Two-arm, parallel, non-inferiority cluster randomized trial
Masking: Single (Outcomes Assessor)
Masking Description:
The investigators responsible for analyzing the data for primary outcomes will be masked.
Primary Purpose: Prevention
Condition  ICMJE Dental Caries
Intervention  ICMJE
  • Device: Silver Diamine Fluoride
    Silver diamine fluoride (SDF)
    Other Name: Advantage Arrest
  • Device: Fluoride Varnishes
    Fluoride varnish (FV)
  • Device: Glass Ionomer
    Glass Ionomer Sealants (GC Fuji IX)
Study Arms  ICMJE
  • Experimental: Simple Prevention

    One drop (0.05 ml) of silver diamine fluoride (Advantage ArrestTM) solution at 38% concentration (2.24 F-ion mg/dose) will be dispensed per child. Posterior tooth surfaces to be treated will be dried, after which the SDF will be applied with a micro-brush to all asymptomatic carious lesions and to all pits and fissures on bicuspids and molar teeth for thirty seconds. Fluoride varnishes (5% NaF) will then be applied to all teeth.

    Dosage frequency will be twice-yearly.

    Interventions:
    • Device: Silver Diamine Fluoride
    • Device: Fluoride Varnishes
  • Active Comparator: Complex Prevention

    Pits and fissures on all bicuspids and molar teeth will be sealed with glass ionomer sealants (GC Fuji IX). Glass ionomer sealants (interim therapeutic restorations) will also be placed on all frank asymptomatic carious lesions. Fluoride varnishes (5% NaF) will then be applied to all teeth.

    Dosage frequency will be twice-yearly.

    Interventions:
    • Device: Fluoride Varnishes
    • Device: Glass Ionomer
