Summary
Professional Crest Whitestrips, a whitening strip, demonstrated superior effectiveness in tooth whitening compared to a custom tray system. This randomized clinical trial found the strip system achieved better results for yellowness, brightness, and overall color.
Area of Science:
- Dentistry
- Cosmetic Dentistry
- Dental Materials
Background:
- Professional vital bleaching systems are widely used for tooth whitening.
- Comparing the efficacy of different professional whitening systems is crucial for clinical practice.
Purpose of the Study:
- To compare the whitening effectiveness of a professional whitening strip system versus a custom tray-based system.
- To evaluate objective color changes in maxillary anterior teeth following professional vital bleaching.
Main Methods:
- A randomized clinical trial involving 69 adult volunteers.
- Participants were randomized to either a 6.5% hydrogen peroxide whitening strip or a custom tray system with hydrogen and carbamide peroxide.
- Objective color measurements (L*a*b*) were taken from digital images of anterior teeth.
Main Results:
- Both treatments significantly improved yellowness, brightness, and overall color (P < 0.01).
- The whitening strip system showed statistically significant superior whitening response for all measured color parameters at the end of treatment compared to the tray system.
- Minor tooth sensitivity and gingival irritation were reported by 35-40% of subjects in both groups.
Conclusions:
- The professional whitening strip system (Professional Crest Whitestrips) is more effective for tooth whitening than the tested custom tray system.
- Both systems offer significant tooth whitening with generally well-tolerated side effects.
- Objective colorimetric analysis provides reliable data for assessing whitening efficacy.
