Examination of the variations between microcrystalline and nano-hydroxyapatite for defense towards dental caries and remineralizing the tooth.
A pattern I’ve observed in latest months is that practical docs and organic dentists are more and more recommending merchandise that include 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 Enamel
Analysis revealed within the scientific literature convincingly demonstrates that hydroxyapatite gives extremely efficient safety towards dental caries. It additionally affords advantages for tooth remineralization. (1, 2)
In truth, the analysis clearly exhibits that hydroxyapatite’s protecting results on the tooth are pretty much as good or higher than fluoride.
Thus, for these wishing to keep away from the organic harm of fluoride publicity, hydroxyapatite is a wonderful and protected different.
The query is, what kind?
Is the nano-hydroxyapatite that’s in a rising share 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 may be carried out mechanically.
Nano-hydroxyapatite is one thing else fully…the particle dimension is massively smaller than the microcrystallized type.
How a lot smaller?
“Nano” is 1000 occasions smaller than “micro”. (3)
In truth, 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 positioned.
Advantages and Dangers
Whereas microcrystalline hydroxyapatite is 100% protected 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 up to now 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 observe 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 towards 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 fast advances in nano-technology itself. (4)
Thus, sensible shoppers could be nicely suggested to make use of warning with merchandise containing nano-hydroxyapatite else they will find yourself as guinea pigs for this expertise.
Whereas anticipated advantages from nano-hydroxyapatite could happen, the unwanted side effects may very well 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 embody cytotoxicity, harm, 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 will not 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 protected.
Thus, should you want to get pleasure from the advantages of remineralizing hydroxyapatite in your oral care merchandise, keep on with firms that solely use the microcrystalline type.
As of this writing, I solely know of 1 firm that gives all these merchandise.
That is the hydroxyapatite tooth powder that I take advantage of and advocate that comprises the protected 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 kids?
If it have been me on this state of affairs, I might politely say no.
The medical analysis merely doesn’t help the protection of nanoparticles for human DNA.
