Summary
Three whitening toothpastes were tested for effectiveness. All three demonstrated a significant tooth whitening effect after eight weeks, with no significant differences between them.
Area of Science:
- Dental Science
- Cosmetic Dentistry
Background:
- Increasing market share of whitening dentifrices.
- Need to assess the efficacy of commercially available products.
Purpose of the Study:
- To evaluate the tooth whitening efficiency of three distinct commercial dentifrices.
- To compare the effectiveness of different whitening toothpaste formulations.
Main Methods:
- Parallel, randomized, double-blind clinical trial.
- Thirty-six subjects with extrinsic tooth stain (A3 or darker).
- Three groups using different dentifrices (Durodont medical fresh and white, Friscodent Zahnweiss, or a combination) twice daily for eight weeks.
Main Results:
- All three dentifrices showed a statistically significant whitening effect compared to baseline after four and eight weeks (p < 0.05).
- No significant differences in whitening efficacy were observed between the three tested groups.
- Both visual shade guide assessment and colorimeter measurements yielded similar results.
Conclusions:
- All tested whitening dentifrices provide a significant tooth whitening effect.
- The specific formulations and RDA values of these dentifrices did not lead to significantly different outcomes in this study.
