NCT07112963

Brief Summary

Purpose: This randomized controlled clinical trial aimed to compare the effectiveness of fluoride varnish, resin infiltrant, and their combination in treating superficial proximal carious lesions in primary molars of children aged 4 to 9 years. Materials and Methods: Twenty-six children with initial proximal caries (E1, E2, D1) on primary molars were randomly assigned to three groups: fluoride varnish only (F), resin infiltration only (RI), and resin infiltration combined with fluoride varnish (RI+F). Treatments were applied according to standardized protocols, and clinical and radiographic evaluations were conducted at 3, 6, 9, and 12 months.

Outcome Measures

Primary Outcomes (1)

  • Caries Lesion Progression

    The primary outcome is the clinical and radiographic assessment of proximal carious lesion progression or arrest in primary molars over a 12-month follow-up period. Lesion status will be evaluated at 3, 6, 9, and 12 months to determine treatment efficacy.

    12 months

Study Arms (3)

Fluoride Varnish Group

ACTIVE COMPARATOR

Participants in this group receive only fluoride varnish applications according to standard clinical protocols. The treatment aims to remineralize early proximal carious lesions and prevent progression.

Drug: Fluoride Varnish

Resin Infiltration Group

EXPERIMENTAL

Participants in this group receive resin infiltration treatment alone, applied following manufacturer guidelines and standardized procedures, aiming to arrest or reverse early enamel carious lesions.

Drug: Fluoride Varnish

Resin Infiltration + Fluoride Varnish Group

EXPERIMENTAL

Participants in this group receive a combined intervention of resin infiltration followed by fluoride varnish application. The combined treatment is intended to maximize caries arrest and promote remineralization of proximal lesions.

Drug: Fluoride Varnish

Interventions

Application of fluoride varnish to proximal surfaces of primary molars following standard clinical protocols to promote remineralization and arrest early carious lesions. Application of resin infiltrant material to proximal non-cavitated carious lesions in primary molars, performed according to manufacturer instructions to arrest lesion progression. Sequential application of resin infiltration followed by fluoride varnish on proximal surfaces of primary molars to maximize caries arrest and remineralization effects.
