Background and Aims:
Self-appearance, including clean and white teeth, impacts confidence. Natural products like tomatoes, rich in vitamin C and lycopene, are promising teeth-whitening agents. This study aims to explore the effects of tomato extract on teeth whitening by comparing different toothpaste formulations.
Methods:
Experimental laboratory methods were employed, utilizing a sample of 20 human premolar teeth. We processed the tomatoes by washing, drying, grinding, macerating with 96% ethanol, and evaporating them to obtain a concentrated form. We incorporated different concentrations of tomato extract (5%, 7.5%, and 10%) into toothpaste formulations. Then, we compared it with negative control and a commercial toothpaste brand (Zact). The toothpaste was applied twice daily for 14 days, followed by rinsing and placement in an artificial saliva solution. Teeth colour change was measured using the shade guide. Statistical analyses, including the Kruskal- Wallis and Dunn-Bonferroni tests, were conducted to determine the significance of colour changes.
Results:
Based on the results, the study found that tooth brightness increased with the concentration of tomato extract in each formula, with higher concentrations leading to more significant improvements.
Conclusions:
This research provides valuable insights into the potential of tomato extract as a natural teeth-whitening agent. Furthermore, the practical applications and potential for commercialization are promising, suggesting that tomato extract could be developed into a widely used product in the dental care industry
