Background: Individuals conform to a perfect smile depending on the condition of their teeth, thus contributing to their overall appearance.
Objective: The current study aimed to check the efficiency of teeth whitening with different materials and measure the effect of roughness of each material in natural human teeth.
Methods: The study was conducted on 30 samples of teeth, including incisors, premolars, and molars, from both males and females, extracted due to orthodontics or periodontics procedures. Teeth were divided into three groups. Each group was washed with different materials daily for one minute for a period of 3 weeks.
Results: After testing and measuring through a spectrophotometer, a significant change was noted between the whitening toothpaste and lemon and baking soda by 0.002 and charcoal toothpaste by 0.012. However, the whitening toothpaste and the charcoal toothpaste showed no significant differences. Contour GT-K machine for roughness measurement showed that the lemon and baking soda increased and then declined to a very
smooth surface. However, the whitening toothpaste showed high roughness, whereas the charcoal toothpaste maintained a stable rough surface.
Conclusion: Most people are concerned about aesthetics and seek to improve it either through safe or unsafe ways. Most people look for easy ways to get teeth whitening, either through home remedies or over-the-counter products. However, charcoal toothpaste showed the most effective color change and is less abrasive than whitening toothpaste and lemon, and baking soda.
