Summary
This study found that common beverages like red wine significantly stain dental composite resins. Different resin materials exhibit varying resistance to staining from drinks such as coffee, tea, and juice.
Area of Science:
- Dental Materials Science
- Biomaterials
Background:
- Dental composite resins are widely used for restorations.
- Color stability of composite resins is crucial for aesthetic outcomes.
- Dietary habits expose restorations to various staining agents.
Purpose of the Study:
- To evaluate the in vitro staining potential of common beverages on different composite resins.
- To compare the staining efficacy of red wine, orange juice, coke, tea, and coffee.
- To assess color changes in composite resins after prolonged immersion.
Main Methods:
- 288 composite resin specimens were divided into six groups.
- Specimens were immersed for 4 weeks in five staining solutions (red wine, orange juice, coke, tea, coffee) or artificial saliva (control).
- Color change (ΔE00) was measured over black and white backgrounds.
Main Results:
- Significant color changes were observed in all composite resins after 4 weeks.
- Staining varied significantly between different composite resin materials.
- Red wine caused the most pronounced staining, with ΔE00 values up to 37.6 (black background) and 51.1 (white background).
- Differences in staining were also significant among the tested beverages.
Conclusions:
- Composite resin color stability is compromised by common dietary beverages.
- Material selection influences the susceptibility to staining.
- Clinicians should advise patients on potential staining from certain food and drink items.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...
