Transcript of What is hydroxyapatite?

Hydroxyapatite, a natural calcium phosphate, is the third most abundant element in the human body and the main component of bone tissue (60%) and the dental tissue (by weight constitutes 95 % -97 % of the enamel , 65 % -70% of the dentin and the 50 % -60% of cement)

Topical application of hydroxyapatite nanoparticles , being a natural part of the tooth , provide high integration with tooth enamel, remineralize dentin surface and occlude dentinal tubules.
What is hydroxyapatite ?
What application have the hydroxyapatite nanoparticles?
What are the benefits?
Treatments applied by dentists in the office block the exposed tubules, eliminating the dentinal hypersensitivity. These include composite resin adhesives , periodontal surgery, laser and even endodontia.
Tooth enamel whitening also can be performed in the dental office using specific procedures based on laser technology, microabrasion or the application of a chemical agent on the tooth surface
The hydroxyapatite nanoparticles also act by filling the tooth enamel surfaces, making them smoother and brighter.
Using this after in-clinic dental whitening helps keep teeth white for a longer period of time.
Tooth sensitivity?
The main benefits of its application are removing dentin hypersensitivity and whitening the tooth enamel, restoring the natural white.
Specific clinic treatments
Dentinal hypersensitivity has been described as an intense and transitory pain as a consequence of the exposure of dentin to thermal, chemical and tactile stimuli, caused by its demineralisation or by gingival recession.
The enamel surface is also important in defining the colour of teeth, because if a tooth is smooth and shaped normally, it will be brighter, while if the surface has irregularities it will be duller and darker, since the reflection of light loses its intensity when it hits the enamel surface.
Discolored teeth?
