A REVOLUTION IN PROPHYLAXIS
Dr. Ralf Breier
A revolution in prophylaxis
We dentists are constantly presented with products offering extensive improvements in dental care. And
yet, so few of them prove themselves in practical experience. So you could imagine my bland response
when my attention was turned to a small presentation stand at a large implantologist convention in
Hamburg 2012. As a dentist, I feel obliged not to rule-out categorical innovations that can potentially
contribute to the patients’ health, and so I took a good hour to listen to the developer’s (Dr. h.c. Andreas
Teichmann - Andjana international) presentation. Although I entertained my doubts about this product, I
decided to test it on a few selected patients.

Figure 1: Crystal formation after mixing the Dentcoat SiO2-Complex
Dentcoat is a highly concentrated mineral
forming fluid which comprises of two ingredients.
The solution forms millions of small SiO2 crystals
(figure 1). The main ingredients are pure alcohol
and a colloidal silicon dioxide complex. When they
are combined, SiO2 crystals are fo rmed in the
alcoholic solution. A hydrolysis reaction with
cleaving lattice-oxygen removes pigments which
were bound to the tooth enamel and binds Si
crystals to the enamel with covalent bonds
ffigure. 2
Figure 2: The crystals bind chemically in the apatite grid.
(figure2). The presence of F-ions, which interact in the
hydrolysis reaction with a Hydroxylapatit scaffold, forms
additional Fluorapatit on the binding sites. These crystals
are hexagonal rods which can be chemically distinguished
only by the presence of F-ions on Hydroxylapatit (-OH).
Fluorapatit has a higher acid tolerance than Hydroxylapatit
and the SiO2 complex is resistant to acids with a pH value
of up to 1.8. .

Following year-long acidic attacks, the
surface of our teeth enamel appear, under a
scanning electron microscope, like a rugged
mountain range with peaks and valleys
(figure 3). After the SiO2 crystals surround
the enamel prisms, the enamel becomes
acid-resistant and is easy to clean. The tooth
surface is also covered with a bio-repulsive
layer. The new crystals are not only
mechanically adhered to the enamel after
their application, but they are also chemically
bound. The valleys are completely covered
with Si-Fluorapatit crystals; the enamel
structure thickens, aligning the crystals in its
structure (figure 4). This effect is visible
during the treatment since the enamel
surface brightens considerably, its opacity
level rises and it assumes a silky shine
(figure 5).

So we achieve a smoother and denser surface
(figure 6). The cleaning becomes easier (figure 7)
and the acidic tolerance is raised by the formation of
complete Fluorapatit crystals (reduced decay and
Periodontitis). Mineral formations occur also in the
dentin surface and the dentin microscopic tubules
(reduced tooth sensibility; figure 8). The patients will
notice this during their treatment. The covalent
bonds prevent the crystals from “washing-out” of
the tooth substance. Last but not least is the
whitening effect. It is caused by the hydrolysis
reaction’s cleansing effect and the changes in the
surface structure which results in better lightreflection.

The Procedure
To obtain the best results, the teeth and root surface
will be cleansed and the surface structure will be
smoothed (the rugged peaks are reduced) prior to
the Dentcoat treatment. If abrasion devices are used,
appropriate silicon polishers (Brownies, Greenies)
should be intensively used. Abrasive polishing
pastes may not be applied because the wax
contained in them might obstruct the teeth enamel
and the dentin micro-structures and therefore hinder
the crystals from binding. The dentist can
alternatively use tooth pastes with high or middle
abrasion, but no additional paraben. The teeth will be
kept dry with the supplied cheek holder and suction
on the tongue level (figure 9). Saliva must not
accumulate on the teeth surface, but the sulcus
should be moistened. After the kit’s two substances
are mixed together, we must wait ten minutes until
crystals can be formed. Now the treatment can
begin. The liquid will be very thinly applied on all
teeth with the applicator (figure 10). The alcohol will
take about three minutes to evaporate before the
reaction begins. The next application will follow after
another three minute pause, and so on. After the last
round we will allow ten minutes for drying. The
complete treatment takes about 45 minutes. After
each round we will see a reduction in the absorption
of new liquid in the teeth and the surface will
gradually assume a silky shiny look.
Figure 9: The cheek retractor keeps the teeth dry.
Figure 10: The liquid is applied with the applicator.
Figure 11: The red-wine test shows a reduction in new surface
discoloration and teeth stone.
The whitening effect varies according to the discoloration of
the teeth (the darker the teeth are before the treatment, the
greater the effect), the surface’s evenness (strong effect on
even surfaces) and the enamel thickness (stronger effect on
thicker enamel). No bleaching agents are used in the
treatment and the teeth’s natural color returns. This procedure
may well bring a change from A4 to A2. Young patients can
get, according to their circumstances, up to A1. New Dentcoat
patients receive two treatments with a two week interval, in
order to assure that all surfaces are reached. Afterwards, each
patient will receive a yearly refreshment treatment to counter
any surface abrasion. Since the gaps between the natural
enamel prisms are filled with each treatment, the enamel
structure is constantly improved, new surface discolorations
are prevented and so is the formation of calculus (figure 11).
Prophylaxis indications

Figure 12–14: Application of Dentcoat with a Perio-Applicator.
• Adult prophylaxis for enamel and dentin
• Children prophylaxis after emergence of the
second molar in enamel maturation.
• Prophylaxis before and after orthodontic treatment
• Geriatric prophylaxis (protection from root caries).
• Sensitive dental necks (permanent occlusion of
dentinal tubules).
• Bioactive teeth whitening.
• Teeth protection after whitening (reduced sensitivity; coffee, tea
and red wine can be consumed immediately).
Conclusion
In Dentistry has witnessed in the past years a
paradigm shift, placing stronger emphasis on
dental prophylaxis and prevention. Our wish as
dentists, to give prevention a higher priority, is fully
shared by our patients. The regular application of
Dentcoat will move us a big step forward in this
direction.
Prospects
We foresee that in the area of periodontal pocket
treatments, the effects of Dentcoat application
with the Perioapplicator, even in inaccessible root
areas (figures 12-14), will allow a continued rapid
anti-inflammatory effect of up to six months. A
similar effect is attained with peri-implant
inflammation forms. We believe that in addition to
the antibacterial effect of the alcohol, the
accumulation of Dentcoat silicon dioxide complex
on the titanium and root surfaces will result in a
longterm anti-bacterial effect.

We would like to conclude with the presentation
with two pictures from our practice. They show two
sulcus formations which were in situ in the some
patient for nine months. Both are free of
inflammation, but the untreated one demonstrates
a significant mineralized plaque formation (figure
15 and 16). We successfully achieved this antibacterial effect also when implemented in
augmentative procedures used to condition the
surface in periodontal and peri-implantation
therapy. I am convinced this is a revolution in
dentistry.
