QSI-Galacto

Quorum Bio Pharmaceutical Co., Ltd’s unique patent technology developed by
SNU’s research institute, in which beneficial bacteria are preserved and only the bad bacteria are suppressed

‘QSI-Galacto’

Quorum Sensing Inhibiting Technology

  • # Powerful prevention of tooth decay
  • # Prevention of gum disease
  • # Remove bad breath
What is
QSI-Galacto?

Quorum Bio Co., Ltd, established by professors of SNU, has researched for more than 4 years to develop QSI-Galacto, the Quorum Sensing Inhibiting Technology.

QSI-Galacto is a harmless natural material found from milk, which can prevent tooth decay, gum disease, and bad breath. This patented component is safe and effective as it preserves beneficial bacteria while the bad bacteria are suppressed.

What is
Quorum Sensing?
“Quorum Sensing, is fatal weakness of bacteria”

There are numerous bacteria in our mouth. Bacteria communicate to each other by their special communication method called ‘Quorum Sensing’. Through this communication, bacteria can call bad bacteria together to create biofilm and cause diseases.

What is
Quorum Sensing
Inhibitor?
“Can’t we just kill the bad bacteria?”

Unfortunately, toothpaste, mouthwash, and other antiseptic products around us, does not only kill the bad bacteria, but also kills the beneficial bacteria.
An inconvenient truth of 99.9% sterilizing effect is that it removes beneficial bacteria from our body. Quorum Sensing Inhibitor prevents bacteria membrane formation, tooth decay, and disease by blocking bacterial communication, without killing all bacteria.

Our immune system can be weakened when beneficial bacteria are removed, and this can increase the risk of getting gum disease, bad breath, and other diseases. In this case, some of bad bacteria can become tolerant to antiseptic substances, which makes the disease harder to be treated.

  • Bacteria call other bacteria together through their communication method called Quorum Sensing.

  • When bad bacteria are gathered, they form biofilm that produces virulence factors.

  • QSI-Galacto blocks bad bacteria’s Quorum Sensing to prevent biofilm formation and virulence factor production from the beginning.

Quorum Bio Healthcare Co., Ltd’ operates SNU’s research institute at
School of Dentistry of SNU, and the effect of QSI-Galacto is proven by experiment.

Quorum Sensing Inhibiting Technology
QSI-Galacto’s Advantages

  • Experiment on inhibiting S.mutans
    (causing dental caries) biofilm

  • Experiment on S.oralis
    (beneficial bacteria) biofilm

Using Lutooth Toothpaste inhibited formation of biofilm of S.mutans,
harmful bacteria in the mouth by 80%, while S.oralis, beneficial bacteria increased.

Safety confirmation through toxicity test to oral cells
Toothpaste including QSI-Galacto : Toxicity test to oral cells took place, and proved that it is non-toxic for long term use.
  • Cell viability according to the
    time and volume
    The amount of toothpaste and time of
    application are
    not affecting on the cells at all.
  • Photo of Cytotoxicity experiment
    All results in different experiment condition
    (the amount of
    toothpaste/time of application)
    are similar which proves that it
    does not
    influence on the cells.
Are you worried about spoilage like mold formation?

This Preservative Free Toothpaste.

  • Asepsis, Antibacterial, Antifungal test completed
  • Powerful antibacterial and antifungal effect
  • Lutooth Quorum Toothpaste does not only kill
    the bad bacteria, but also shows antibacterial
    effect by suppressing the growth of bacteria.
  • It is very safe for human body as it does not
    kill bacteria
  • Experiment to prove that there is
    no bacteria in the toothpaste

  • Experiment to prove that it has
    antifungal effect

  • Experiment to prove that it has
    antibacterial (cavity bacteria) effect

Amazing Tooth Whitening Effect
Without Hydrogen Peroxide!

Before and After using the Lutooth Toothpaste Comparison of the surface of teeth (magnified a thousand times)
You can find that the pigment staying deposited on the cleavage(B) and the dent (C) of the tooth and yellowed is cleanly removed after using Lutooth Quorum Toothpaste. This method is especially suitable for removing pigments formed by smoking and drinking coffee.
Whitening effect proved by figures
Whitening effect test conducted at School of Dentistry of SNU.
You can see average 2 levels tooth whitening effect.
Comparison of whitening effect of different ingredients
Toothpaste with QSI-Galacto was compared to famous whitening ingredients: charcoal and baking soda. The result shows that Toothpaste with QSI-Galacto had much high tooth whitening effect
