Summary
Tooth whitening effectively lightened pit and fissure stains. However, the presence of reservoirs in bleaching trays did not significantly impact the whitening results for these stains.
Area of Science:
- Dental Materials Science
- Aesthetic Dentistry
Background:
- Occlusal pit and fissure stains can negatively impact tooth aesthetics.
- Tooth whitening agents are commonly used to improve tooth shade.
Purpose of the Study:
- To determine the efficacy of tooth whitening on occlusal pit and fissure stains.
- To assess the influence of bleaching tray reservoirs on stain lightening.
Main Methods:
- Extracted molars were treated with 10% or 22% carbamide peroxide or tap water.
- Custom bleaching trays, with or without reservoirs, were utilized.
- Shade evaluations of occlusal stains were performed before and after treatment.
Main Results:
- Both carbamide peroxide concentrations significantly lightened pit and fissure stains (P < 0.0005).
- The control group (tap water) showed no significant shade change (P = 0.816).
- Reservoirs in bleaching trays did not significantly affect stain lightening (P = 0.658).
Conclusions:
- Tooth whitening agents are effective in reducing the shade of occlusal pit and fissure stains.
- Bleaching tray reservoir design does not appear to influence the lightening of these specific stains.

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.

01:03Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

01:13Special Staining Techniques
Specialized staining techniques play a vital role in microbiology by enabling the visualization of specific bacterial structures that remain undetectable with standard microscopy methods. These techniques not only enhance the structural visualization of bacterial cells but also provide critical insights into their pathogenicity and classification. Additionally, they support diagnostic and research endeavors in microbiology by identifying key bacterial features.Capsule Staining for Virulence...
01:26Differential Staining Technique
Differential staining is an essential microbiological technique that exploits variations in cell wall structures to classify and identify microorganisms. It facilitates the distinction of bacteria, aiding in diagnostic and research applications. Two of the most widely used differential staining methods are Gram staining and acid-fast staining, both of which rely on the chemical and structural differences in bacterial cell walls.Gram Staining TechniqueGram staining differentiates bacteria by...
