The purpose of this study was to determine the combined effect of an organic substance (mucin as a substitute for salivary organic substances), chlorhexidine, and an iron compound/tea solution on the changes in the color of esthetic Class V dental restorative materials. Color of a glass ionomer, resin-modified glass ionomer, compomer and flowable resin composite of A2 shade, respectively, was determined according to the CIELAB color scale relative to the standard illuminant D65. Color was…

Comparison of color stability of a composite resin in different color media
Investigation of the effects of different common drinks consumed by patients on one of the widely used composites in dentistry finds staining solutions and immersion time are significant factors that affect color stability of composite resins.
Assessing the effect of staining solutions and repolishing on composite resin color change found that color change of composite restorations depends on the type and shade of composite resin as well as patient’s nutritional habits.
Evaluation of Surface Condition and Food Solution on the Color Stability of Dental Restoration Materials
For this study, specimens were prepared using five types of composite resin and resin-reinforced glass ionomer Fuji II LC, and 29 days precipitation was done in four kinds of solution, which were soy

Nano-filling composite resins are the most successful aesthetic restorative materials, whereas the commonly used resin-modified glass ionomers exhibit more aesthetically divergent results following the use of mouthwashes.
Discoloration of coating resins exposed to staining solutions in vitro.
Staining response was most pronounced after coffee immersion for White Coat and after tea immersion for the experimental material, exceeding the clinically acceptable discoloration threshold value of deltaE=3.3.
The Effect of Brilliant Blue-Based Plaque-Staining Agents on Aesthetic Orthodontic Appliances
Under in vitro conditions, the regular use of the BBPSA for 90 days visibly improved the unfavourable colour change caused by the black tea, and the braces’ green-red colour expression was positively affected by theBBPSA.
Can the chlorhexidine gluconate solution potentiate the staining of polycrystalline ceramic brackets?
It is concluded that chlorhexidine potentiates the staining caused by red wine in polycrystalline ceramic brackets.

Staining Potential of Different Coffee Products Available in the Saudi Market on Resin Based Composite Restoration
The aim is to evaluate the staining effect of different brands of coffee (available in the Saudi Market) on the Composite restorations. 40 extracted natural teeth were collected, (cleaning and
The effect of the oxygen inhibition layer on interfacial bond strengths and stain resistance of dental resin composites
It was suggested that incremental bond strength between composite layers is not wholly reliant on surface inhibition, where an increased OIL thickness resulted in increased stain susceptibility.


Development of methods to enhance extrinsic tooth discoloration for comparison of toothpastes. 1. Studies in vitro.
These studies in vitro suggest that the chlorhexidine tea stain model can be manipulated to enhance stain and thereby should improve discrimination between stain inhibition formulations.
Color stability of restorative resins.
Most staining was superficial and could be removed with regular oral hygiene; however, residual staining, which might become cumulative, was recorded.

The effectiveness of seven denture cleansers on tea stain removal from PMMA acrylic resin.
Denture cleansing agents containing hypochlorite and Boots Denture Cleaning Powder exhibited the ability to remove stain from the denture base materials most effectively, as well as reducing the activity of denture cleaning agents and hence increased stain and plaque retention.
In vivo early human dental plaque formation on different supporting substances. A scanning electron microscopic and bacteriological study.
The amount of early deposits on different substances seems to be related to the degree of their surface roughness, while plaque formation was qualitatively similar.
Iron staining of the acquired enamel pellicle after exposure to tannic acid or chlorhexidine: preliminary report.
The ability of iron to stain the integument after pretreatment with the two denaturants was studied in a human model and the denaturing effect of an acidic environment was also included.
Light microscopic and color television image analysis of the development of staining on chlorhexidine-treated surfaces.
The results of this in vitro method provided further evidence for a dietary aetiology to chlorhexidine staining and were consistent with clinical findings.
