Nano hydroxyapatite vs hydroxyapatite

Juntavee, N., Juntavee, A. & Plongniras, P. Remineralization potential of nano-hydroxyapatite on enamel and cementum surrounding margin of computer-aided design and computer-aided manufacturing Differential effect of hydroxyapatite nano-particle versus nano-rod decorated titanium micro-surface on osseointegration Author links open overlay panel Long Bai a b c Yanlian Liu a Zhibin Du b c Zeming Weng a Wei Yao e Xiangyu Zhang a Xiaobo Huang a Xiaohong Yao a Ross Crawford b c Ruiqiang Hang a Di Huang d Bin Tang a Yin Xiao b c The claim is that nano-hydroxyapatite (Nano-HAp) can help strengthen teeth through remineralization — and preliminary research has backed this claim. Remineralization means filling in micro cracks and fissures on the tooth’s surface, as well as helping rebuild damaged spots where cavities are just beginning to take hold. The aim of this study was to compare the efficacy of sodium fluoride mouthrinse and nano- hydroxyapatite (nano-HA) for the remineralization of incipient caries. Materials and methods: After obtaining different concentrations of nano-HA (0-2-5-10%), 60 sound premolars fixed in acrylic blocks were coated with nail polish except for one surface.

The claim is that nano-hydroxyapatite (Nano-HAp) can help strengthen teeth through remineralization — and preliminary research has backed this claim. Remineralization means filling in micro cracks and fissures on the tooth’s surface, as well as helping rebuild damaged spots where cavities are just beginning to take hold. Some toothpaste and mouthrinses contain a nanocrystal form of hydroxyapatite (nHA) or a zinc combination (Zn-HA).

Hydroxyapatite (HA) is considered to form major component of bones and teeth. Synthesis of hydroxyapatite (Calcium phosphate, Ca10(PO4)6(OH)2) was carried out to produce nano powders. 2020-07-07 · The aim of the study was to assess the efficacy of three methods of enamel remineralization on initial approximal caries: (1) a nano-hydroxyapatite gel, (2) gaseous ozone therapy, (3) combination Nano-hydroxyapatite toothpaste vs Fluoride toothpaste in reducing dental hypersensitivity In the present clinical trial, it was evaluated the efficacy of a toothpaste containing nanoXIM•CarePaste in reducing dental hypersensitivity, in comparison with a toothpaste containing fluoride. Nano-hydroxyapatite crystals small enough to mimic the size of natural dentinal hydroxyapatite (20 nm) have been used to repair micrometer-sized tooth surface defects in vitro.

Toothpaste that contains nano-hydroxyapatite has particle sizes between 20-80 nanometers (nm). Unlike the previous formula used, Nano-hydroxyapatite is a reduced and modified for the better version of it, which adheres naturally to the existing hydroxyapatite in the teeth, penetrating the dental tubules, reducing sensitivity, whilst still mineralizing and repairing any enamel defect that exists at the same time.

Certainly for human use, there are many possibilities – especially in association with radioisotopes – as demonstrated previously, when the group labelled HA with technetium-99m and doped with holmium-166. nano-hydroxyapatite as a potential fertilizer in improving phosphorous efficiency based on the hypothesis that nano-sized particles can potentially move in the soil and reach the plant roots through the mass flow of soil water to roots created by transpiration [Bala et al., 2014, Liu and Lal, 2014). Hydroxyapatite nanoparticles (HAP-NP) are incorporated in oral care products such as toothpastes and mouthwashes to treat dental sensitivity or to promote enamel remineralisation. Despite the good performance of HAP-NP in this application, it is important to ensure its safety for consumers.

There are concerns on the safety of nano-Hydroxyapatite arising from the fact that the nanoparticles can be absorbed and enter into the cells. For that reason, an Opinion on the safety of nano-Hydroxyapatite when used up to 10% in oral cosmetic products was requested to the SCCS. Bioactive polymer/hydroxyapatite (nano)composites are currently being intensively investigated as materials for promotion of bone tissue regeneration and reconstruction. 2020-04-03 · But, the pure form of hydroxyapatite is white, but impurities can make it grey, yellow, or yellowish-green. Below infographic shows more details regarding the difference between fluorapatite and hydroxyapatite. Summary – Fluorapatite vs Hydroxyapatite.
