Examination of the variations between microcrystalline and nano-hydroxyapatite for defense in opposition to dental caries and remineralizing the enamel.
A development I’ve observed in current months is that purposeful medical doctors and organic dentists are more and more recommending merchandise that comprise nano-hydroxyapatite to their sufferers.
What’s hydroxyapatite, or “HA” as it’s generally abbreviated?
HA is sort of merely floor bone with solely the moisture extracted.
Nothing else is added or eliminated.
Hydroxyapatite Protects and Remineralizes Tooth
Analysis printed within the scientific literature convincingly demonstrates that hydroxyapatite gives extremely efficient safety in opposition to dental caries. It additionally presents advantages for tooth remineralization. (1, 2)
The truth is, the analysis clearly exhibits that hydroxyapatite’s protecting results on the enamel are pretty much as good or higher than fluoride.
Thus, for these wishing to keep away from the organic injury of fluoride publicity, hydroxyapatite is a superb and secure different.
The query is, what sort?
Is the nano-hydroxyapatite that’s in a rising proportion of fluoride-free, remineralizing oral care merchandise the best way to go?
Let’s have a look.
Microcrystalline vs Nano
Microcrystalline hydroxyapatite is the type of dehydrated bone that’s floor to as effective a particle dimension as will be carried out mechanically.
Nano-hydroxyapatite is one thing else solely…the particle dimension is massively smaller than the microcrystallized type.
How a lot smaller?
“Nano” is 1000 occasions smaller than “micro”. (3)
The truth is, nanoparticles are so small that they will simply breach the partitions of cells and even the nuclear membrane inside a single cell itself…the place DNA is situated.
Advantages and Dangers
Whereas microcrystalline hydroxyapatite is 100% secure to be used in oral care merchandise (right here’s the place I get mine), it’s best to keep away from the nano model.
Analysis so far means that there are dangers for mutations to DNA. This happens from the breaching of the nanoparticles previous the nuclear membranes of particular person cells.
Please notice that I’m not questioning the analysis on nano-hydroxyapatite.
The advantages are fairly compelling and credible in that it’s certainly useful in defending in opposition to cavities in addition to for remineralization functions.
Nevertheless, there’s RISK in utilizing nano-hydroxyapatite as nicely. Some different practitioners are glossing over these risks by recommending merchandise containing them.
In brief, progress within the evaluation of well being dangers from nanoparticles, aka “nano-toxicology”, is being far outstripped by the speedy advances in nano-technology itself. (4)
Thus, good shoppers can be nicely suggested to make use of warning with merchandise containing nano-hydroxyapatite else they will find yourself as guinea pigs for this know-how.
Whereas anticipated advantages from nano-hydroxyapatite might happen, the unwanted effects might be far worse than tooth decay!
A few of the dangers from nanoparticles are already recognized within the literature. Dr. Al Danenberg DDS warns about these risks which embrace cytotoxicity, injury, and mutations to mobile DNA. (5)
This happens because of the breaching of the nuclear membrane (not simply the cell membrane as mentioned within the pro-nanoparticle analysis!).
Nano-Hydroxyapatite Is Not Pure
In brief, the place microcrystalline hydroxyapatite is a pure substance with a particle dimension that the physique acknowledges and might cope with, nano-hydroxyapatite shouldn’t be.
Nano-hydroxyapatite is the artificial type of hydroxyapatite with confirmed advantages however loads of unknown dangers to the integrity of your DNA.
The particle dimension of nano-hydroxyapatite (or any nanoparticle for that matter) is so tiny that it simply breaches the blood-brain barrier in addition to the nuclear member defending the DNA of each cell.
Abstract
In closing, it is very important know that whereas research present nano-hydroxyapatite to be efficacious, it has not been confirmed secure.
Thus, should you want to take pleasure in the advantages of remineralizing hydroxyapatite in your oral care merchandise, stick to firms that solely use the microcrystalline type.
As of this writing, I solely know of 1 firm that provides some of these merchandise.
That is the hydroxyapatite tooth powder that I take advantage of and advocate that accommodates the secure particle (non-nano) type.
Do you like to make your personal tooth powder?
This bag of microcrystalline hydroxyapatite is ideal for the DIY oral care recipes you make at house.
Lastly, what to do with practitioners who’re recommending nano-hydroxyapatite merchandise for you or your youngsters?
If it have been me on this scenario, I might politely say no.
The medical analysis merely doesn’t help the security of nanoparticles for human DNA.
