X-PUR Remin

1. What is Nano Medical Hydroxyapatite?
The main substance of our teeth (97% of enamel & 70% of dentin) is hydroxyapatite, a crystalline form of calcium phosphate. Even if it is the hardest substances in the human body, tooth enamel constantly suffers microscopic scratches, wear and loss of minerals as a result of attacks by biofilm acids. X-PUR Remin’s main ingredient, Medical Hydroxyapatite, is almost the same substance as the naturally occurring hydroxyapatite in the mouth but in nanoparticles size. While providing replacement hydroxyapatite to the teeth, it is safe, biocompatible and edible.

2. Why use a toothpaste with Nano Medical Hydroxyapatite?
The idea in offering toothpaste with Nano Medical Hydroxyapatite as the main ingredient is to support a naturally occurring function in the mouth, the restorative role of saliva. In fact, enamel is made up of closely packed hydroxyapatite rods, separated by tiny channels about 50 nanometers wide. As demineralization occurs, the biofilm dissolves these hydroxyapatite rods. Saliva plays an important role by providing calcium and phosphate, the building block of hydroxyapatite. It neutralizes acids caused by plaque bacteria and restores lost mineral, so that the enamel becomes remineralize. If conditions such as excess biofilm, inadequate saliva flow or heavy intake of acidic food are present, sufficient mineral is necessary to protect against caries and tooth sensitivity. Nano Medical Hydroxyapatite supplements the salivary mineral and reverses incipient caries and white spot lesions.

3. Is X-PUR Remin a good toothpaste for xerostomics patients (dry mouth)?
The principal issue for dry mouth patients is losing the restorative role of saliva.

Saliva plays an important role. It not only neutralizes acids caused by plaque bacteria, but also provides calcium and phosphate ions, the building blocks of hydroxyapatite, which diffuse back into the enamel to restore lost mineral, so that the enamel becomes remineralized.

For patients with dry mouth, the balance is broken in favor of demineralization, so a very fast proliferation of oral plaque may result in dental caries.

Demineralization and remineralization of our tooth enamel take place constantly. The tooth surface is easily colonized by bacteria in the form of dental plaque, especially in minute fissures or spaces between the teeth where a toothbrush cannot reach. Enamel is made up of closely packed hydroxyapatite rods, separated by tiny channels about 50 nanometers wide. Acids produced by plaque bacteria seep into these channels and can dissolve the rods, causing the enamel to become demineralize.

4. How deep goes into the dentin enamel?
One in vitro study using natural extracted teeth showed X-PUR Remin’s medical hydroxyapatite penetrated near the area of the dentin enamel junction, at about 500 microns in depth from the enamel surface.

5. How does Nano Medical Hydroxyapatite absorb cariogenic bacteria/periodontal associated bacteria (gram positive/negative) and not all the good bacteria that we have in our mouths?
Hydroxyapatite in general has a strong propensity to bind with protein, including all forms of bacteria. This probably includes «good» bacteria as well but in the oral cavity, tends to bind strongly to gram positive cariogenic bacteria such as streptococcus mutans. One reason is because they can only collect and multiply on the tooth surface, not in saliva or on the oral mucosa. Thus, when the tooth surface is directly brushed with toothpaste containing hydroxyapatite, these bacteria in particular become attached to the hydroxyapatite during brushing, facilitating their removal on rinsing from the mouth.

6. Is X-PUR Remin safe for people with dairy allergies?
Yes. Its ingredients are not derived from dairy products. In fact, the calcium in it is not derived from animal sources, but from calcium mines (from a natural geological source).

7. What is Sodium-N-lauroyl-L-glutamate?
Is a sodium salt made with glutamic acid and lauric acid. It provides moderate detergency and foaming force, is biodegradable, and its mild acidity (like human skin's) makes it very safe to the skin.

8. What ingredients do you use for "flavour”?
The flavor is a mixture of natural and synthetic ingredients, but is mostly plant derived.

9. What is a B-glycerrhetinic acid?
B-glycerrhetinic acid is an ingredient used to reduce and prevent gum disease. It is made from liquorice root.

10. I believe the nano hydroxyapatite is a form of calcium. Is this correct?
Nano medical hydroxyapatite is a crystalline form of calcium phosphate (the same substance as our bones and teeth).

X-PUR Gommes et Pastilles 100% Xylitol

1. Can I recommend your X-PUR Products to pregnant women?
Yes, we would even recommend you to do so. The consumed Xylitol during pregnancy will optimize the chances to give birth to a baby with healthy and beautiful teeth.

2. Do your products contain Gluten?
No, if our products would contain some, we’d have no other choices but to indicate it on the wrapping since gluten comes from wheat.

3. Is our Xylitol made from birch bark or corn husk?
The source of Xylitol is unimportant, once the birch or the corn is processed into Xylose (what is used to produce Xylitol), it become impossible to know the source.

4. With all the GMO corn, how Xylitol can possibly be GMO free?
We hereby certify that the used raw materials for the manufacturing of X-PUR Gums & Pastilles 100% Xylitol are purely synthetic and free from GMO.
We can confirm that neither genetic modification technology has been applied, nor any genetically modified ingredients used. Therefore we can certify that the final products are GMO free.

5. Were X-PUR products in contact with allergens (including nuts) during the production process?

6. Does the citrus extract increase mouth acidity?
Our X-PUR Gums & Pastilles 100% Xylitol will only have a positive impact on your oral pH (increasing it) due to the high concentration of Xylitol.


1. Will XyliMelts raise blood sugar? Diabetes?
Not very much, XyliMelts contain no sugar. They do contain Xylitol, a natural sweetener.
Xylitol is known to raise blood glucose by ½ as much as sugar does.
One XyliMelts self-adhering disc contains 550 mg (1/2 gram) of Xylitol.
XyliMelts work by stimulating saliva production and coating and lubricating the mouth.
Saliva dissolves the XyliMelts over the course of approximately 1-4 hours during the day, and 3-8 hours while sleeping (time varies depending on mouth movement and how much saliva you have).
Due to the slow release of that ½ gram of Xylitol, there is very little released into the body at any given time.

2. What is the adhesive made out of on the Xylimelts (ingredients)?
Acacia gum (gum arabic), which is sap from a tree that grows in North Africa, and calcium carbonate. The tree is called Acacia.

3. Stain removal from pillow case/bedding?
Acacia gum includes plant proteins and the color is likely a protein. Enzymes break proteins so enzymes for washing clothes is required. A customer used Zout pre-wash spray with triple enzyme formula and it worked perfectly with regular detergent.

4. XyliMelts seem to be affecting my voice – is this possible?
XyliMelts include cellulose gum to form a gel when mixed with saliva. This gel coats the mouth to soothe and lubricate it and keep it moisturized. People with dry mouth want these three benefits. The gel coats the vocal cords and gives people a feeling of being hoarse or needing to clear their throats. Because the hoarseness or need for throat clearing is not a response to an infection, which is the usual cause of hoarseness, it is not in any way unhealthy. Some people do not like the feeling, but it is impossible to get the benefits of a lubricating gel without this drawback. For most people, the benefits are worth the hoarseness or need for throat clearing.

5. How many calories is in each XyliMelts disc?
Each disc has 1.2 calories from the Xylitol and .3 calories from the acacia gum, for a total of 1.5 calories per disc.

6. How much Calcium is in each XyliMelts disc?
Each disc contains 3.4 milligrams of calcium. (Compare to attached list showing calcium in other foods)

. What is the pH Level of XyliMelts?
Measured in the standard way, the pH is 8.1 (non-acidic, slightly basic)

8. Are XyliMelts gluten Free?
Yes, XyliMelts is gluten free!

9. Do XyliMelts contain sugar?
No, they are made with Xylitol, which is a natural sweetener!

10. Does XyliMelts interfere with taking any other medications?
Xylimelts does not interfere with any other medications.

11. Do you need a prescription for XyliMelts?
No, they are an over the counter item.

12. Are there any side effects to using XyliMelts?
No, but if you use 24 discs within 24 hours it may cause diarrhea

13. What is the difference between Mild-Mint (regular) and Mint-Free?
Mild-Mint has a slight mint flavor (most popular ordered) & Mint-Free has a slight sweetness flavor due to the Xylitol, which is a natural sweetener.

14. What if XyliMelts cause itching or burning or sores in the mouth?
A small percentage of people can be/or can become sensitive to the ingredient used in the adhesive side known as Acacia gum. There is no permanent harm.

15. Where is the Xylitol derived from? Can be either birchwood or corn?
Our Xylitol is derived from corn cobs, refined to the point that there is no corn protein.

16. Are there carbohydrates in XyliMelts?
Yes, Xylitol is a carbohydrate, however, it has half of the caloric value per unit weight of other carbohydrates such as starch and sugar.

Sodium Fluoride

1. Is the rosin (resin/colophony) contained in your white varnish allergenic?
X-PUR NaF White Varnish uses a refined and purified from of rosin. Since the introduction of this new form of rosin, there has been no allergic reaction reported.

2. What is the pH of the Opti-Rinse (NaF Oral Rinse)?
The pH is 6.8 to 7.

3. What is the RDA (Relative Dentin Abrasion) of the NaF Gel?
The RDA is below 10 = Low abrasion

4. Were X-PUR products in contact with allergens (including nuts) during the production process?

5. Is Sodium Fluoride (NaF) safe for patients with decreased kidney function?
Considerable research has been done over the years regarding this issue and the majority of researchers and clinicians agree that there is no problem with fluoride and kidney diseases. In fact, fluoride is not absorbed mucousally. With a rinse and expectorate product, there is only a minimum amount of fluoride that ever reaches the system. Some fluoride is absorbed in the stomach and small intestine while the other part of fluoride is excreted in feces. The renal system does not play a part in the metabolism or excretion of fluoride.

Perichlor Chlorhexidine

1. Is it normal that my patients are getting yellow stains on their teeth when using your rinse?
Yes, the Chlorhexidine may produce surface staining of the teeth. Adequate tooth brushing may prevent these stains, which are not harmful and may be removed by a dental team.

2. Were X-PUR products in contact with allergens (including nuts) during the production process?


1. Is Gengigel coming from the comb of a rooster?
No, the HA in Gengigel is not from an animal source. Please keep in mind that the HA from a rooster comb is by far not the same quality as the HA in Gengigel. HA from an animal source doesn’t have the same molecular weight and purity.

The HA in Gengigel is extracted from the bacteria gained by a fermentation process of soy. However, due to the fermentation process, there is absolutely no trace of soy left. So no issue of soy allergy.

The HA in Gengigel is of the highest quality, it’s molecular weight and purity (roughly 10x more pure than rooster comb HA) guarantee optimal efficacy.

Brossettes interdentaires Curaprox

1. Could you confirm that the CPS «Prime» are not coated with a protection? (i.e. plastic) What is the rational for a client that is used to nylon/plastic coated brushes from other brand?
The CPS «Prime» are not plastic coated. The only brushes of Curaprox that are plastic coated are the CPS «Soft Implant». There is no reason for the CPS «Prime» to be plastic coated as the wire will never come in touch with the tooth surface due to the way the bristles are bound into the wire unlike the competitor brands which are spiral bound.

2. What are the difference between them and Curaprox?
The main difference between Curaprox and them is the quality of the product. Curaprox brushes last 5 times longer than the TEPE ones.


1. Cetacaine cannot be used on large areas of denuded or inflamed tissue?
We believe that the reason why Cetacaine cannot be used on large areas of denuded or inflamed tissue is to prevent excessive systemic absorption of the anesthetic.

The good news is that Cetacaine isn’t used on large areas of denuded or inflamed tissue because it is applied drop by drop in periodontal pockets. The concern is, most likely, with the spray, as it is more difficult to control the quantity of Cetacaine being applied to the tissue which subsequently, could lead to large areas of denuded or inflamed tissue being affected which, could potentially, increase the likelihood of excessive systemic absorption.

Conclusion: At the dose we recommend and using the delivery method we demonstrate (i.e. 0.4 ml syringe), Cetacaine is a safe topical anesthetic.


1. Can one take magnesium along with Periostat?
Periostat should not be taken with any di-valent cation such as calcium & magnesium and zinc, because part of the efficacy of Periostat is its ability to bind the cation, zinc (and calcium) in the collagenase molecule thus inhibiting its activity.

2. Can one take dairy along with Periostat?
Periostat should not be taken with dairy because it contains calcium which can reduce it’s efficacy, therefore it should be taken 1 hour before or after a meal or dairy (ie: milk, cheese).

3. How does Periostat work?
Periostat helps to suppress certain tissue-destroying enzymes that the body overproduces in response to the chronic bacterial infection of the mouth. Research clearly demonstrates that enzyme suppression is essential for a stable outcome in the treatment of periodontal disease.

4. Why should my patients take Periostat?
It controls harmful levels of tissue-destroying enzymes and helps the body to repair and rebuild damaged tissue and bone. Periostat, combined with the removal of infectious bacteria from your teeth by your dental professional (a deep-cleaning procedure called scaling & root planing), results in a periodontally stable, healthy mouth.

5. What is the posology?
Take 1 Periostat capsule twice daily, morning and evening (one hour before or two hours after a meal) with a full glass of water.

6. How long should my patients take Periostat?
Studies have shown that more stable results are achieved with longer term use such as 6-9 months.

7. What happens when a patient stops taking Periostat?
Benefits will continue for months following Periostat therapy, and vary by individual dependent on the management of risk factors (oral hygiene, smoking, diabetes, etc). It is important to continue maintenance visits with your dental professional every 3-4 months.

8. Is Periostat a covered benefit by group insurance plans?
Yes! The majority of insurance carriers in Canada consider Periostat therapy a covered benefit under extended health prescription plans.

9. Is there a substitute for Periostat?
No! There is no substitute or generic for Periostat.

10. Is Periostat effective in the treatment of periodontal disease in smokers and diabetics?
Evidence shows that Periostat (combined with scaling & root planing) is very effective in controlling periodontal disease in smokers and diabetics, and will actually contribute to better control of diabetes.

11. Are there any contraindications my patients should be aware of prior to taking Periostat?
Pregnant or nursing women, children, Tetracycline intolerant individuals or liver disease sufferers should not take Periostat.

12. How does Periostat affect other medication?
• Downward dosing of Coumadin may be required.
• Efficacy of oral contraceptives may be decreased.
• Do not take antacids or iron preps within 4 hours of Periostat.
• During Penicillin/antibiotic treatment, discontinue Periostat. Resume Periostat one week following Penicillin/antibiotic use.

13. Are there side-effects associated with Periostat?
Clinical testing has proven that Periostat is very well tolerated. Because side-effects are similar to placebo, Periostat does not cause sun sensitivity, nausea or antibiotic resistance.

14. Anything else?
Yes! Because of Periostat’s revolutionary success in controlling periodontal disease, Periostat is now being tested with continued success in treating other inflammatory diseases, such as acne, rosacea, rheumatoid arthritis, and cardiovascular disease. Recognizing the systemic link between the health of our mouth and the health of our body is at the forefront of medical technology. Treat periodontal disease seriously!

15. What if a patient forgets to take a capsule?
Just resume taking the next scheduled dose. Never double up to replace the missed capsule.

16. Would Periostat be indicated for Psoriatic arthritis? Since PT is effective to treat Psoriasis and arthritis I thought I would check in with you as I have not heard of this connection before. (or even of Psoriasis arthritis?)
Both psoriasis and arthritis are often associated with elevated bio-markers and mediators of systemic inflammation (e.g., elevated hs-C-reactive protein, IL-6,MMP-9 in their blood/circulation), and periostat has been shown to reduce these biomarkers systemically, it is possible that periostat could be beneficial to either or both of these inflammatory diseases….for example, sub-antimicrobial doses of doxycycline (periostat;oracea) have shown evidence of efficacy in rheumatoid arthritis (O’dell et al ,2006)…other studies have shown efficacy of doxycycline in osteoarthritis (Brandt KD,1995,J.Rheumatology,43:149-151)…other studies indicate efficacy in various skin diseases.

X-PUR Crystal

1. What is the glycerin derivative or source contained in X-PUR Crystal?
The small amount of agent you are concerned with is a USP Grade Glycerin (glycerol 99+%). We are now in our International Patent Process.

X-PUR Pro-Synergix

1. How long will last the whitening results obtained by your Pro-Synergix?
We cannot give a precise answer since it depends mostly on living habits. Ex: caffeine, red wine, tobacco consumption and dental hygiene habits.

2. What is the pH of the Pro-Synergix?
The pH is 6.0 to 7.5

Lasers Photon

1. What is the battery life of the unit?
It is 300 times charge.

2. Can the Photon 3W LLLT treats cancer cells that have an ointment on it?
The settings with the wand are the same: 20 seconds + 4J biostimulation, 40 seconds + 8j bioinhibition. For the wand, it requires a lot more power and this is a factory preset. The Photon works as long as 810 is the right wavelength for his chemical. For the 100J/cm2, it can be set for this. It can be used with either the handpiece or the wand. Our Sales Consultant can check the outputs and work with you to set the unit. It is possible to do a custom setting which can be saved in the menu.

3. Is the Photon supposed to go silent or light med loud sound because they are always stuck on loud?
The volume control only affects during the manipulation of the screen MENU. But during the procedures, every time you step on the pedal, the sound is always the same, you can’t control the volume or mute. Regardless what kind of handpiece you are using, the sound is the same. The purpose is to let the user aware that there is a power coming from the fiber, wand or bleaching hand piece and they have to be cautious of the effects if they overused or hit the wrong target.

MENU: 3 sound options (low, med, high) + mute
WHILE IN USE: only one sound, regardless of what was selected in the MENU. This is for the safety of the users.
