Hypothesis
The study aims to assess the effectiveness of two nicotine medicated chewing gums on stain removal compared to a whitening gum and saliva.
Conclusion
The nicotine replacement therapy chewing gums were more effective in removing extrinsic tooth stains than the whitening gum and saliva.
Supporting Evidence
- Medicated chewing gums A and B removed significantly more stain than the confectionary gum C and saliva.
- After 60 minutes, chewing gum A had a ΔE score of 10.80, while chewing gum C had a ΔE score of 5.00.
- Both nicotine gums continued to remove more stain than the confectionary gum and saliva after 120 minutes.
Takeaway
Chewing gums with nicotine can help make your teeth whiter by removing stains better than regular whitening gum or just saliva.
Methodology
Bovine incisors were stained and then treated with different chewing gums and saliva, with color changes measured using a spectrophotometer.
Potential Biases
Potential bias due to funding from Novartis Consumer Health, the manufacturer of the tested products.
Limitations
The study was conducted in vitro, which may not fully replicate real-life conditions.
