Assessment of Enamel Color Stability of Resins Infiltration Treatment in Human Teeth: A Systematic Review

Abstract

(1) The evolution of techniques and materials used in dentistry has led to the introduction of a technique known as micro-infiltration, using ICON infiltrating resin. The purpose of this study was to evaluate whether the resin infiltrant can remain stable in the enamel color of human teeth over time or if it causes discoloration and review current knowledge on color stability based on the literature selected solely on studies performed on human teeth and to provide a perspective on the methods proposed by clinicians in the infiltration procedure; (2) Methods: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement; (3) Results: Twelve studies were selected for this review. The study results suggest that the device content is sufficiently comprehensive. The reviewers expressed strong support for the device’s content for assessing the quality of reviews. The paper summarizes current reports regarding the color stability assessment of enamel treated by in- filtration resin confirmed in in vitro and in vivo studies; (4) Conclusions: Based on these considerations, the resin infiltration method can be recommended to improve the appearance of enamel lesions. The infiltrated lesions remained chromatically stable, showing no significant color changes in the long term.

Esthetic effects and color stability of resin infiltration on demineralized enamel lesions: A systematic review

“…The stability of the resin infiltration is affected by technical errors (improper handling of the resin), incomplete evaporation of the solvent, and loss of the oxygen inhibition layer. [ 29 30 ] In addition, the composition of the resin infiltrant, where triethylene glycol dimethacrylate (TEGDMA) is a highly hydrophilic monomer that is less resistant to degeneration in the oral environment, may contribute to color instability, which has been linked to the pigmentation tendency of TEGDMA due to the water carrier effect for various pigments. [ 30 31 ] The effects of pigmentation can also be affected by the duration of exposure and the intensity of coloring.…”

“…[ 24 ] In all studies, the infiltrated resin was polished to reduce the surface porosity and remove the oxygen inhibition layer. [ 11 22 , 24 30 ] Polishing has resulted in a significant decrease in Δ E values because dyes are absorbed on the surface with low penetration into resin materials or the dental substrate. [ 30 ] Thus, the polished infiltrated lesions showed less discoloration than the unpolished infiltrated lesions.…”
