Clinical Effectiveness of In-office Bleaching Activated With a LED/Laser Device
Tooth Discoloration
About this trial
This is an interventional supportive care trial for Tooth Discoloration focused on measuring tooth bleaching, bleaching agent, hydrogen peroxide
Eligibility Criteria
Inclusion Criteria:
- Participants should be at least 18 years old;
- Participants should have good general and oral health
- Participants should have six caries-free maxillary anterior teeth without restorations on the labial surfaces
- Participants should be willing to sign a consent form
- Participants should have central incisors darker than shade C2.
Exclusion Criteria:
- Participants that had undergone tooth-whitening procedures
- Participants that had labial anterior restorations, were pregnant or lactating.
- Participants with severe internal tooth discoloration (such as tetracycline stains, fluorosis, pulpless teeth).
- Participants with bruxism habits or any gross pathology in the mouth

The tooth bleaching will be performed using a high hydrogen peroxide concentration (35%) without light-activation with LED/light device
The tooth bleaching will be performed with a low hydrogen peroxide concentration (20%) without light activation with a LED/laser device
The tooth bleaching will be performed with a high hydrogen peroxide concentration (35%) associated with LED/laser light activation
The tooth bleaching will be performed with a low hydrogen peroxide concentration (20%) associated with LED/laser light activation
