About this study

Official title: Efficacy of the Application of the Low-viscosity Resin Infiltration on the Change of Color of the Enamel White Spot Lesions

this study aimed to assess the effect of the application of the low-viscosity Icon resin infiltrate on the color change of the diagnosed white spot enamel lesions (WSLs) over 3-, 6-, and 12-m follow-up periods. The ICDAS scoring system was used to visually diagnose WSLs in a total of 96 anterior teeth in 49 participants and the teeth were then were evaluated for their color change using a spectrophotometer. According to the manufacturer directions the Icon kit was applied to the WSLs-diagnosed teeth as follows: the WSLs were treated with 15% hydrofluoric acid (Icon-Etch) was applied to the lesions for 120 seconds then it was rinsed for 30 seconds. Next, the etched WSLs were treated with 99% ethanol (Icon-dry) and for 30 seconds. Then the Icon-Resin was applied and light cured for 40 seconds. The change of color was done after 3-, 6- and 12-month . The mean and standard deviation values were statistically analyzed with the repeated measure ANOVA test and the Paired sample t-test.

Read the detailed description

The early caries may not be noticeable till it appears as rough enamel surface that might has chalky-white or even dark spots of brown color with no cavities formed. These spots reported were referred to as the white spot enamel lesions, that can be visually diagnosed with the ICDAS scoring method (International Caries Detection and Assessment System) that was proposed for the assessment of caries including early enamel lesions that are not yet cavitated and appear after through dryness of the enamel surface.

Remineralization of the white spots enamel lesion presents the first choice treatment option. Still it has some short-outcomes, such as the staining-ability and unreliable esthetic results. It was reported that the Icon resin infiltration to masking the white spot enamel lesion at the minute of its application without a detectable change of color up to a period of six months. The Icon resin infiltration technique depends on its low-viscosity that enables its penetration into enamel surface through capillary action, occluding the micro porosities created in the enamel as a result of the white enamel lesions development. So that, the progression of the lesion would be stopped.

Therefore, this clinical study was conducted to assess the effectiveness of the application of the Icon resin infiltration on the change of the color change of the white spot enamel lesions at follow-up periods of 3-, 6-, and 12-months.

What is being measured

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

  1. Color change

    Using the intraoral spectrophotometer, which measures the color differences at the specific follow-up periods. The color difference (ΔE) was calculated with the equation: ΔE*Lab= [(ΔL 2) + (Δa 2) + (Δb 2)] ½. Where L* value represents the lightness of an object, The degree of redness and greenness is represented by a* values, while the degree of blue and yellow components of color was determined by b* values. A higher Delta E means more significant color shift.

    Measured: Immediate after the application of the Icon resin

  2. Color change

    Using the intraoral spectrophotometer, which measures the color differences at the specific follow-up periods. The color difference (ΔE) was calculated with the equation: ΔE*Lab= [(ΔL 2) + (Δa 2) + (Δb 2)] ½. Where L* value represents the lightness of an object, The degree of redness and greenness is represented by a* values, while the degree of blue and yellow components of color was determined by b* values. A higher Delta E means more significant color shift.

    Measured: At 3 months

  3. Color change

    Using the intraoral spectrophotometer, which measures the color differences at the specific follow-up periods. The color difference (ΔE) was calculated with the equation: ΔE*Lab= [(ΔL 2) + (Δa 2) + (Δb 2)] ½. Where L* value represents the lightness of an object, The degree of redness and greenness is represented by a* values, while the degree of blue and yellow components of color was determined by b* values. A higher Delta E means more significant color shift.

    Measured: At 6 months

  4. Color change

    Using the intraoral spectrophotometer, which measures the color differences at the specific follow-up periods. The color difference (ΔE) was calculated with the equation: ΔE*Lab= [(ΔL 2) + (Δa 2) + (Δb 2)] ½. Where L* value represents the lightness of an object, The degree of redness and greenness is represented by a* values, while the degree of blue and yellow components of color was determined by b* values. A higher Delta E means more significant color shift.

    Measured: At 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Icon resin application in people with White Spot Lesion of Tooth, run by National Research Centre, Egypt at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Color change (time frame: Immediate after the application of the Icon resin). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2023.
