Polyvinylpyrrolidone (PVP): Enhancing Whitening Efficacy

PVP is widely recognized in oral care for its stain-removal capabilities. Its inclusion in whitening formulations aims to improve the appearance of enamel by addressing discolouration from various sources.

  • Study Overview: This study evaluated the effectiveness of toothbrushing with whitening toothpaste containing PVP and blue covarine in altering the shade of stained human enamel.

  • Key Findings:

    • Shade Improvement: Toothpaste containing PVP and blue covarine demonstrated significant improvements in enamel shade after both 1,000 and 5,000 brushing cycles.

    • Comparative Efficacy: The whitening effect was more pronounced after 5,000 cycles, indicating the cumulative benefit of continued use.

  • Conclusion: The incorporation of PVP in toothpaste formulations effectively enhances stain removal and improves tooth shade over time.
