NCT07803757

Brief Summary

This study will evaluate the clinical performance of glass ionomer cervical restorations placed using the Silver-Modified Atraumatic Restorative Technique (SMART) compared with conventional restorative treatment in elderly cancer patients with cervical carious lesions. The trial is a 12-month randomized clinical trial with four parallel arms and a 1:1 allocation ratio. Two SMART arms will receive 38% silver diamine fluoride (SDF) and potassium iodide followed by either high-viscosity glass ionomer cement (HVGIC) or resin-modified glass ionomer cement (RMGIC), while the conventional arms will receive standard tooth preparation followed by HVGIC or RMGIC without SDF. The primary outcome is retention of the restoration, assessed using USPHS criteria. Secondary outcomes include postoperative hypersensitivity, marginal integrity, recurrent caries, average duration of treatment, anatomic form, color match, surface roughness, marginal discoloration, and patient satisfaction (VAS). Patients will be followed at baseline, 3, 6, and 12 months. The study aims to determine whether the minimally invasive SMART approach offers comparable clinical performance to conventional treatment while reducing chair time and discomfort in a medically vulnerable elderly cancer population.

Outcome Measures

Primary Outcomes (1)

  • Retention of Restoration

    Evaluation of the presence and integrity of the restoration over the follow-up period, assessed using USPHS criteria (Zhao et al., 2018): Alpha (A) - restoration present; Bravo (B) - partial loss, clinically acceptable; Charlie (C) - clinically unacceptable partial/total loss; Delta (D) - immediate replacement necessary.

    Baseline, 3 months, 6 months, and 12 months

Secondary Outcomes (8)

  • Postoperative Hypersensitivity

    Baseline, 3 months, 6 months, and 12 months

  • Marginal Integrity

    Baseline, 3 months, 6 months, and 12 months

  • Recurrent Caries

    Baseline, 3 months, 6 months, and 12 months

  • Average Duration of Treatment

    perioperatively

  • Anatomic Form

    Baseline, 3 months, 6 months, and 12 months

  • +3 more secondary outcomes

Study Arms (4)

SMART with High-Viscosity GIC

EXPERIMENTAL

Application of 38% Silver Diamine Fluoride (SDF) and potassium iodide to the carious lesion, followed by restoration with High-Viscosity Glass Ionomer Cement (HVGIC, Riva Light Cure) according to tooth location, using the Silver-Modified Atraumatic Restorative Technique (SMART), without mechanical caries removal.

Other: Silver Diamine Fluoride (SDF, 38%)Other: High-Viscosity Glass Ionomer Cement

SMART with Resin-Modified GIC

EXPERIMENTAL

Application of 38% Silver Diamine Fluoride (SDF) and potassium iodide to the carious lesion, followed by restoration with Resin-Modified Glass Ionomer Cement (RMGIC, Riva Self Cure), using the Silver-Modified Atraumatic Restorative Technique (SMART), without mechanical caries removal.

Other: Silver Diamine Fluoride (SDF, 38%)Other: Resin-Modified Glass Ionomer Cement

Conventional with Resin-Modified GIC

EXPERIMENTAL

Conventional mechanical tooth preparation (excavation of caries with hand instruments and rotary burs, cavity conditioning with polyacrylic acid) followed by restoration with Resin-Modified Glass Ionomer Cement (RMGIC, Riva Self Cure), without prior SDF application.

Procedure: Conventional Tooth PreparationOther: Resin-Modified Glass Ionomer Cement

Conventional with High-Viscosity GIC

ACTIVE COMPARATOR

Conventional mechanical tooth preparation (excavation of caries with hand instruments and rotary burs, cavity conditioning with polyacrylic acid) followed by restoration with High-Viscosity Glass Ionomer Cement (HVGIC, Riva Light Cure) according to tooth location, without prior SDF application.

Procedure: Conventional Tooth PreparationOther: High-Viscosity Glass Ionomer Cement

Interventions

Conventional mechanical excavation of carious dentin using sharp hand instruments and round steel burs in a slow-speed handpiece, followed by cavity conditioning with 10% polyacrylic acid, rinsing, and drying, prior to restoration. No SDF is applied in this procedure.

Conventional with High-Viscosity GICConventional with Resin-Modified GIC

38% Silver Diamine Fluoride applied to the carious lesion using a micro brush for one minute, followed by application of potassium iodide (KI) in esthetically sensitive areas to reduce black staining, prior to restoration. Used in the two SMART arms only, with no mechanical removal of carious dentin.

SMART with High-Viscosity GICSMART with Resin-Modified GIC

High-viscosity glass ionomer restorative cement placed and light-cured according to tooth location, following either SDF application (SMART arm) or conventional mechanical tooth preparation (control arm).
