Brief Summary

This randomized clinical trial and laboratory study was conducted to: Compare the effectiveness of zinc-carbonated nano-hydroxyapatite, arginine, and fluoride-containing toothpastes for treating white spot lesions associated with orthodontically treated teeth by using:

  • Computerized image software analysis.
  • Energy dispersive X-ray analysis.

Outcome Measures

Primary Outcomes (2)

  • the size

    Photographic assessment of the images will be done for quantifying the size (in mm2) of the white spot lesions and the affected tooth's labial surface by using an image processing software, ImageJ analysis software and to ensure accuracy of values, image calibration will be carried out, and the scale of the image analysis software will be pre-set. After the software calculates the values of the entire area of the tooth and the size of the WSL, the area affected by white spot lesions will be expressed as a percentage of the total tooth surface: WSLs %= Area of WSL/ Area of the labial tooth surface\*100.

    1) Baseline 2) 3-month evaluation 3) 6-month evaluation

  • the color change

    Using the Standardized CIE Lab\* system within Adobe Photoshop software, L\*a\*b values will be analyzed for each tooth and the color changes between carious and healthy enamel (∆E\*ab), as well as changes between different time points (∆E\*ab), will be calculated by = Δ E = (Δ L 2 + Δ a2 + Δ b2) ½. ΔE values between 1 and 3.7 are not only acceptable but also often go unnoticed in various colors, especially darker shades. Conversely, when ΔE exceeds 3.7, the color change could be clinically visible, indicating a noticeable color mismatch. According to the degrees of color changes evaluated 6 months after treatment, the teeth will be divided into the following three types: Type 1: The whitish, opaque color is completely masked Type 2: The whitish opaque color is partially masked but not completely Type 3: The whitish opaque color shows little

PARTICIPANT, OUTCOMES ASSESSOR
Masking Details
The toothpastes are sourced from international markets, and both the participants and the outcome assessor will remain unaware of the active remineralizing agent in the toothpaste. This ensures that neither the participants nor the outcome assessor will be informed about the assigned intervention, preventing their expectations from influencing the study results. The examiner was blinded to participants' codes and previous WSL scores during dental assessments. However, blinding to the type of toothpaste used was not possible. Blinding during image analysis was also unfeasible, but this limitation was deemed manageable since the outcome relied on objective computer-based data, minimizing potential bias

Model Details: This study is a randomized controlled trial involving 21 participants ages 12 to 18 years. They will be examined and chosen randomly for the study. Participants will be divided equally into three groups: Group 1 will use zinc carbonate nano-hydroxyapatite toothpaste twice daily; Group 2 will apply 8% arginine and calcium carbonate-containing toothpaste twice daily; and Group 3 will apply fluoridated toothpaste twice daily. Assessment of white spot lesions will be carried out using digital photographs before remineralizing agent application (baseline) and at 3, and 6 month intervals.
