Summary
Nanohydroxyapatite (nHA) offers superior properties for dental applications compared to hydroxyapatite (HA). This review explores nHA
Area of Science:
- Biomaterials Science
- Nanotechnology in Dentistry
- Dental Hard Tissue Engineering
Background:
- Dental hard tissues, enamel and dentin, are primarily composed of hydroxyapatite (HA).
- Nanotechnology enables the use of nanohydroxyapatite (nHA) with enhanced properties over bulk HA.
- nHA exhibits superior solubility, surface energy, and biocompatibility due to its nanoscale structure.
Purpose of the Study:
- To review the diverse applications of nanohydroxyapatite (nHA) in various dental fields.
- To highlight nHA's role in preventive, restorative, and regenerative dentistry.
- To discuss nHA's potential in managing dentinal hypersensitivity and improving dental implants.
Main Methods:
- Comprehensive literature review of studies involving nanohydroxyapatite in dental formulations.
- Analysis of research on nHA's incorporation into dentifrices, mouth rinses, pastes, and restorative materials.
- Evaluation of nHA's efficacy in dental implant coatings and periodontal defect reconstruction.
Main Results:
- nHA-based products are effective in preventing dental caries and remineralizing tooth structure.
- nHA nanocomposites, impression materials, and ceramics show high efficacy in restoring tooth deformities.
- nHA coatings enhance dental implant osseointegration, and nHA aids in reducing dentinal hypersensitivity.
Conclusions:
- Nanohydroxyapatite (nHA) presents significant advantages over conventional hydroxyapatite (HA) in dentistry.
- nHA is a versatile nanomaterial with broad applications in preventive, restorative, and regenerative dental care.
- Further research into nHA applications promises advancements in comprehensive oral healthcare solutions.

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...

01:31Essential Minerals for Bone Health
4.0K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
