About this study

The SMART technique, which stands for "Silver Modified Atraumatic Restorative Treatment," combines the use of Silver Diamine Fluoride (SDF) with atraumatic restorative treatment methods to manage dental caries.SDF helps strengthen the tooth structure and arrests caries, while atraumatic restorative treatment utilizes high-viscosity glass ionomer cements to remove decayed tissue and repair the tooth with minimal invasion.

Patients between the ages of 4-9 who meet ICDAS II (International Caries Detection and Assessment System) 4-5-6 criteria and need restoration of asymptomatic primary molars with unilateral or multifaceted carious cavities will be included. Volunteers will be randomly divided into 2 groups and the treatments of primary molars will be completed using SMART, SMART + LED light techniques.The teeth in all groups will be cleaned of decay using an excavator first, and then Diagnodent values will be checked.

Group 1 (SMART only): 1 drop of SDF solution will be applied to the cavity for 1 minute with a rubbing motion using a bond brush. Then potassium iodide solution will be applied to prevent discoloration. Following the application, the lesion will be washed with water for 10 seconds and the unreacted SDF solution will be removed from the cavity with cotton pellets, leaving a moist shiny surface.

Group 2: (SMART + LED): 1 drop of SDF will be applied to the cavity for 1 min by rubbing the solution. Then LED light (D-Light Pro, GC Europe) will be applied for 20 s in continuous mode from a distance of approximately 1 cm. The following procedure will be the same as SMART only group.

Following SDF applications and activation, 2 weeks later all groups will be checked by diagnodent and restored with high viscosity glass ionomer cements (EQUIA Forte HT, GC, Tokyo, Japan) in accordance with the manufacturers instructions, and the restoration will be covered with a sealing agent (EQUIA Forte Coat, GC, Tokyo, Japan).

Before the procedure, demographic and dental data of the child volunteer, such as age, gender, brushing frequency, and number of teeth treated, will be recorded.

The US Public Health Service criteria (retention,anatomical form, surface roughness, , secondary caries, marginal discoloration and marginal integrity) and Modified FDI criteria will be used for clinical evaluation of restorations. The restorations will be evaluated clinically and radiologically at baseline 3., 6. and 12. months.

Treatment and study plan

SDF+KI+LED Light 20s

Procedure

After the silver diamine fluoride (SDF) and potassiım iodide (KI) application, 20-second LED light will be applied to the cavity.

SDF+KI

Procedure

Silver diamine fluoride (SDF) and potassium iodide(KI) will be applied.

Primary outcomes

  1. 1.Change from 3 months to 12 months regarding "Anatomic form"

    Time frame: 3-month,6-month,12 month

    alpha: The general contour of the restorations follows the contour bravo: the general contour of the restoration does not follow the contour of the tooth charlie: The restoration has an overhang does

  2. Change from 3 months to 12 months regarding "Marginal adaptation"

    Time frame: 3-month,6-month,12 month

    alpha: Explorer does not catch or has one-way catch when drawn across the restoration/tooth interface bravo: explorer falls into crevice drawn across the restoration/tooth interface charlie: Dentin or base is exposed along the margin

  3. Change from 3 months to 12 months regarding "Surface roughness"

    Time frame: 3-month,6-month,12 month

    alpha: the surface of the restoration does not have any surface defects bravo: the surface of the restoration has minimal surface defects charlie: the surface of the restoration has severe surface defects

  4. Change from 3 months to 12 months regarding "Marginal staining"

    Time frame: 3-month,6-month,12 month

    alpha: there is no discoloration between the restorations and tooth bravo: there is discoloration on less than half of the circumferential margin charlie: there is discoloration on more than half of the circumferential margin

  5. Change from 3 months to 12 months regarding "Retention"

    Time frame: 3-month,6-month,12 month

    alpha: intact bravo: chipped/loss of material charlie: complete loss of crown

  6. Change from 3 months to 12 months regarding "Incisal wear"

    Time frame: 3-month,6-month,12 month

    alpha: intact bravo: wear of occlusal surface without tooth surface exposure charlie: wear of occlusal surface with tooth surface exposure

  7. Functional properties according to revised FDI (World Dental Federation) criteria.

    Time frame: 3-month,6-month,12 month

    Functional properties:

    F2: Marginal adaptation measured by visual examination, short air drying, 250 μm probe.

    F3:Proximal contact point measured by visual examination and 25/50/100 μm blades.

    F4: Form and contour measured by visual examination. F5: Occlusion and occlusal wear measured by visual examination and articulation paper.

    Method of aggregation is frequency and percentage. Measuring unit is scoring system (Ordinal, scores 1-5). (1) Clinically excellent. (sufficient). (5) Clinically poor (entirely insufficient).
