Summary
Adding CPP-ACP paste to tooth bleaching agents can improve enamel surface properties. This blend reduces adverse effects, enhancing tooth bleaching outcomes.
Area of Science:
- Dental Materials Science
- Biomaterials
- Surface Chemistry
Background:
- Tooth bleaching agents can negatively impact enamel surface properties.
- CPP-ACP paste is known for its remineralizing potential.
Purpose of the Study:
- To evaluate the effect of combining CPP-ACP paste with carbamide peroxide and hydrogen peroxide on bleached enamel.
- To assess changes in enamel surface hardness, roughness, and morphology.
Main Methods:
- Bovine incisors were bleached using hydrogen peroxide, carbamide peroxide, CPP-ACP paste, or blends at various ratios.
- Surface hardness and roughness were measured before and after bleaching.
- Enamel morphology was examined using Scanning Electron Microscopy (SEM).
Main Results:
- Bleaching with CPP-ACP paste and peroxide blends generally increased enamel hardness and roughness.
- SEM analysis indicated mineral deposition on the enamel surface.
- Higher concentrations of CPP-ACP paste did not yield significantly greater benefits.
Conclusions:
- Combining CPP-ACP paste with carbamide/hydrogen peroxides can mitigate negative side-effects of tooth bleaching on enamel.
- This approach offers a potential strategy to improve the safety of dental bleaching procedures.

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.

01:18Porosity in Cement Paste
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
