Coloration of provisional restoration materials: a comparison of the effects of mouth rinses and green tea

Abstract

PurposeThe present study aimed to evaluate the color stability of provisional restorative materials stored in different mouth rinses and green tea extract for 14 days.Materials and methodsForty cylinders of fixed provisional restoration material of 15-mm diameter and 2-mm thickness were prepared. The samples were separated into four storage solutions (three different mouth rinses and green tea) (n=10). The values of L*, a*, and b* were determined before and after storage in the solutions using a spectrophotometer, and the ΔE* value was calculated. The effect of mouth rinses and green tea extract on the color change of provisional restoration materials was determined with one-way analyses of variance. The Tamhane multiple comparison analysis was used to determine the differences between the groups (p<0.05).ResultsThe color stability of the provisional restoration materials varies depending on the solution. Listerine mouth rinse showed more color change than Sensodyne or Colgate did. Minimal color change was found in the green tea solution.ConclusionThe effect of mouth rinses on the color stability of fixed temporary restorative materials is remarkable. As green tea shows less color change, it can be suggested as an alternative to mouth rinses.

Pit and fissure nanocomposite sealants reinforced with organically modified montmorillonite: A study of their mechanical properties, surface roughness and color stability

“…The importance of color stability in dental restorative materials due to esthetic reasons is reflected by many studies dedicated to the evaluation of color changes caused by discoloration factors, polishing and bleaching treatments etc [49][50][51][52] . Several reports regarding restorative materials claim that color alteration is perceptible when ΔE>1, clinical acceptable values are limited to ΔE<3.3 [53][54][55] .…”

Surface Roughness and Color stability of Provisional Restorative Materials Fabricated Using Different Methods After Immersion in Various Storage Media

“…The least amount of color stability possible should be considered while selecting materials and techniques. The color stability of the temporary materials is a problem when the temporary restoration is in the aesthetic zone to prevent discoloration in the oral cavity from various beverages and teeth-cleaning agents [4,5] . The surface topography of temporary resin restorations has an impact on the neighboring gingival tissue's periodontal health.…”

“…Besides that, The surface roughness can be a cause of changes in materials color, which might affect the aesthetic aspect of restorations [4] . Surface roughness of temporary crowns is influenced by material type, manufacturing method, and kind of surface polishing [5] .…”
