Summary
Light activation sources do not improve in-office vital tooth bleaching efficacy or speed. This review found conflicting evidence on light
Area of Science:
- Dental Aesthetics
- Cosmetic Dentistry
- Tooth Whitening
Background:
- Vital bleaching is a popular cosmetic dental procedure.
- In-office and at-home systems use peroxide gels.
- Some in-office treatments incorporate light activation.
Purpose of the Study:
- To review and summarize the literature on light-activation sources in in-office tooth bleaching.
- To evaluate the effectiveness of light sources in enhancing dental whitening.
Main Methods:
- Literature search conducted on Medline (PubMed) from 2003 to 2013.
- Focused on articles concerning light activation sources and in-office tooth bleaching effectiveness.
Main Results:
- Conflicting evidence exists regarding the benefit of light activation for tooth whitening.
- Light activation sources did not demonstrate increased bleaching efficacy.
- Light activation sources did not accelerate the bleaching process.
Conclusions:
- The use of light activators in vital tooth bleaching does not enhance efficacy or speed.
- Factors like stain type, initial tooth color, and age influence bleaching outcomes.
