AI Summary & Key Takeaways
AI InsightData were analyzed using the paired sample t-test and ANOVA (α=0.05).Results: Statistically significant differences were found between the control group and the bleached groups according to color changevalues (p0.05).Conclusions: The office bleaching agents may affect the color and translucency parameters of composite resins depending on thestructural properties.

Abstract
Aim: The study aimed to evaluate the relationship between the caries frequency, which was determined using different caries indexesObjective: The aim of this study was to investigate the effect of in-office bleaching agents on the color and translucency of differentresin composites.Materials and Methods: Twenty-four disk-shaped specimens with 1 mm thickness and 8 mm diameter were fabricated from fivedifferent resin composites. The specimens were then divided into three subgroups, two office bleaching groups (40% OpalescenceBoost, 38% Whitesmile Power Whitening) and one control group (n=8). All specimens were polymerized for 40 s with a LED lightcuringunit. Color measurement was performed using a spectrophotometer. Bleaching agents were applied to the experimentalgroups in accordance with the manufacturer's instructions for 14 days, while the specimens in the control group were kept in distilledwater only. Translucency parameters of the specimens before and after bleaching and the color changes after bleaching werecalculated using CIE L*a*b* color coordinates. Data were analyzed using the paired sample t-test and ANOVA (α=0.05).Results: Statistically significant differences were found between the control group and the bleached groups according to color changevalues (p0.05).Conclusions: The office bleaching agents may affect the color and translucency parameters of composite resins depending on thestructural properties.
