Objectives: To verify the tooth whitening effect of toothpaste containing seaweed and establish a basis for the development of functional toothpaste that whitens teeth using natural extracts.
Methods: Clinical trials were conducted with the participation of 70 volunteers. There was a negative control group (general toothpaste), positive control group (commercially available whitening toothpaste), and test groups A and B. They were examined before and 6 weeks and 12 weeks after their use of VITA Easyshade V for transposition to assess their tooth color and BB Checke to assess them for halitosis. Moreover, with the use of Dentobuff strips, their pH and stimulated saliva were measured; each measurement was conducted three times, and the average value was recorded.
Results: The findings verified that the tooth whitening effect of the toothpaste containing algae was similar to, if not slightly better than, that of a commercially available whitening toothpaste. In addition, the toothpaste containing seaweed reduced all halitosis, and saliva outflow became more effective as the seaweed content concentration increased.
Conclusions: The effects of natural extracts on tooth whitening have been gradually demonstrated, but when used in products such as toothpaste, the effects are unlikely to appear immediately; it takes about 6 months for the effects to show. Therefore, clinical trials should be advanced, and the number of representatives should be increased. Nevertheless, the demand for tooth whitening is increasing, and it is sensible to whiten teeth using natural extracts to form a basis for developing functional toothpaste that will alleviate bad breath.
