Investigating the impact of whitening toothpastes on bioactive resin-based restorative materials: a comparative analysis

Year: 2024

Type: article

Abstract: OBJECTIVE: To assess the color stability and surface roughness of bioactive resin-based composite following exposure to coffee staining and brushing with whitening toothpastes. METHODS: ) and surface roughness were measured. RESULTS: ranging from 4.82 ± 1.72 to 11.15 ± 1.44 post-brushing compared to baseline with every toothpaste, with the lowest value observed in Fll with W-TP (p < 0.001). For individual color parameters (ΔL, Δa, Δb), AP exhibited significantly greater ΔL changes between baseline and post-brushing compared to FZ, BFP, and FII (p < 0.001). No significant differences were observed for Δa or Δb across materials at any measurement stage (p > 0.05). Additionally, the effect of toothpaste type on individual parameters, as well as the interaction between material and toothpaste type, was nonsignificant (p > 0.05). CONCLUSION: All materials tested showed increased roughness and unacceptable staining with none returning to baseline color or achieving acceptable color change post toothbrushing, irrespective of toothpaste type. CLINICAL SIGNIFICANCE: Understanding the effects of staining and whitening toothpastes on bioactive resin-based composites is important for optimizing material selection and maintenance protocols to ensure long-lasting esthetic outcomes in patients prone to staining.
