Comparison between the effect of commercially available chemical teeth whitening paste and teeth whitening paste containing ingredients of herbal origin on human enamel.

Background: Dentistry plays a crucial role in shaping the esthetics of a person and thus boosts the self-esteem of an individual. Whitening of the teeth is the most popular procedure where surface and deep stain removal whitens the teeth. Teeth whitening is achieved by professional application of chemicals and can also be self-administered by numerous products available. The most popular product is teeth whitening paste which is simple in application and easily available. Recently, teeth whitening tooth paste is commercially available where natural ingredients or their derivatives are used instead of chemicals for teeth whitening.

Aims: To investigate and compare the effect of commercially available chemical teeth whitening toothpaste and teeth whitening toothpaste containing ingredients of herbal origin on human enamel (at the Department of Oral and Maxillofacial Pathology, Royal Dental College, Kerala, India).

Materials And Methods: An study with a duration of 14 days was conducted.

Settings And Design: An study was conducted twenty samples were taken and assembled in to two groups of 10 each. Group A for teeth treated with conventional chemical toothpaste and group B for teeth treated with toothpaste containing ingredients of herbal origin. Premolars extracted for orthodontic purpose were checked for shade with Vita 3D shade guide and were observed under a stereomicroscope for surface morphology before the procedure. Each section was cleansed twice daily for 1 min with specified toothpaste and soft bristle toothbrush according to their groups and then cleansed with tap water and stored again in the same solution. After 14 days, the teeth were tested for the shade using vita 3D shade guide and surface morphology using stereomicroscope.

Statistical Analysis Used: Student's unpaired -test.

Results And Conclusion: In this 14-day study, the chemical whitening toothpaste showed better whitening of teeth than toothpaste containing ingredient of herbal origin, whereas the surface irregularities was increased on the surface of the enamel with chemical whitening toothpaste when compared with toothpaste containing ingrtedients of herbal origin.
