Fulltext PDFAim:To evaluate the esthetic improvement and staining resistance of a resin infiltration system, CPP-ACPF-containing paste, and universal adhesive on artificially demineralized enamel using spectrophotometry.
Methodology: Thirty-two extracted human maxillary incisors were cleaned and stored in 0.1% thymol. All surfaces except the labial were covered with nail varnish. Artificial white spot lesions were created by immersing specimens in a demineralizing solution (CaCl₂, KH₂PO₄, acetic acid, KOH; pH 4.4) for 4 days. Teeth were randomly divided into four groups (n=8): Group 1 – Control (artificial saliva), Group 2 – Resin infiltrant (ICON), Group 3 – MI Paste Plus (CPP-ACPF), and Group 4 – Scotchbond Universal Adhesive. Treatments were applied according to manufacturer instructions, followed by 7 days of pH cycling. Spectrophotometric color measurements were recorded at baseline, after demineralization, post-treatment, and after 8-day exposure to black tea (10 minutes daily).
Results: Demineralization significantly reduced lightness (∆L) across all groups. ICON resin infiltrant showed a statistically significant improvement in ∆L and maintained this improvement after staining. MI Paste Plus and Scotchbond adhesive did not demonstrate significant differences from the control group in esthetic improvement or stain resistance.
Conclusion: ICON resin infiltrant provides superior esthetic improvement and stain resistance for white spot lesions compared to CPP-ACPF paste, universal adhesive, and artificial saliva.
