Implication

Randomized trial examines color stability and surface changes in composite resins after exposure to polyphenol-rich beverages, suggesting significant implications for dental aesthetics.

Key Points

The study assesses the effects of polyphenol-rich beverages on color stability and elemental composition of composite resins.
128 composite resin specimens immersed in three types of tea for 14 days.
Color change, translucency, and weight loss measured using spectrophotometric methods.
SEM-EDS analysis conducted to evaluate changes in surface morphology and elemental composition.
Black tea caused the greatest color change (ΔE 00) in both resin types (p < 0.05).
SEM-EDS analysis showed increased carbon and reduced silicon levels after tea exposure.
ΔE 00 correlated positively with total polyphenol content (ρ = 0.614) and surface carbon (ρ = 0.660), and negatively with silicon (ρ = -0.503) (all p < 0.001).
