Nano-hydroxyapatite was proven to be better than other treatments at reducing sensitivity against evaporative stimuli, such as an air blast, and tactile stimuli, such as tapping the tooth with a dental instrument. However, no difference was seen between nano-hydroxyapatite and other treatments for cold stimuli. [30]
Nano-hydroxyapatite is one nanophase ceramic that is used as a bone substitute. Nano grain size increases the bonding, growth, and differentiation of osteoblasts onto the ceramic. The surfaces of nanophase ceramics can also be modified to be porous allowing osteoblasts to create bone within the structure.
For this reason, the number of toothpastes and mouthwashes that already incorporate nano-hydroxyapatite as a desensitizing agent is increasing. [14] Bioglass is a relatively new technology in toothpaste formulations. BioMin, a bioactive glass of calcium fluoro phosphosilicate, provides faster and longer lasting relief against sensitivity ...
In 1980, the Japanese company, Sangi Co., Ltd., launched APADENT, the world's first remineralizing toothpaste to use a nano-form of hydroxyapatite, the main component of tooth enamel, rather than fluoride, to remineralize areas of mineral loss below the surface of tooth enamel (incipient caries lesions).
P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.
A travel expert revealed the science of why food and drinks taste different on a plane — and what he chooses to order once the beverage cart comes around.
Nanoscale hydroxyapatite crystals form a layered structure with the deposited collagen at the surface of the implant. Following these reactions, bone growth continues as the newly recruited cells continue to function and facilitate tissue growth and repair. The Bioglass implant continues to degrade and be converted to new ECM material.
More Fermentation, Fewer (Tummy) Problems. Fermentation has long been praised for its benefits on gut health, and you're more likely to encounter these benefits when leaving the U.S. for more ...
