Summary
Dentist-supervised tooth bleaching is effective using at-home carbamide peroxide or in-office hydrogen peroxide. Emerging technologies may enhance results and reduce tooth sensitivity.
Area of Science:
- Dental Aesthetics
- Evidence-Based Dentistry
Background:
- Tooth bleaching is a key procedure in cosmetic dentistry.
- Clinicians face challenges with various bleaching options and managing adverse effects like tooth sensitivity.
Purpose of the Study:
- To review and consolidate current scientific knowledge on dentist-supervised tooth bleaching for vital teeth.
- To compare at-home and in-office bleaching protocols based on clinical trial data.
Main Methods:
- Systematic review of randomized clinical trials (RCTs) and meta-analyses adhering to CONSORT guidelines.
- Searched PubMed, Scopus, and Web of Science databases using terms like "tooth bleaching" and "randomized clinical trial."
- Analyzed 203 selected studies comparing clinical protocols, color change, and adverse effects.
Main Results:
- Daily at-home bleaching with 10% carbamide peroxide or lower-concentration hydrogen peroxide for 3-4 weeks is effective.
- In-office bleaching protocols vary based on hydrogen peroxide concentration and gel pH.
- Novel technologies like violet LEDs and infrared lasers show potential for improved efficacy and reduced sensitivity.
Conclusions:
- Effective bleaching protocols exist for both at-home and in-office treatments.
- Ongoing research is crucial for developing better desensitization strategies to manage tooth sensitivity.
- Emerging technologies warrant further investigation for their role in tooth whitening and patient comfort.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

5.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

2.3K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
