AQUAJET AND ORAL HEALTH
Spaces between the teeth are the places where bacteria accumulates and multiplies. Bacteria lives in the soft dental plaque;
and produces the acid which destroys tooth’s enamel and leads to gingival mucosa inflammation.
Crowns, prosthetic dentures, and dental appliances are dicult to clean regularly, which also causes the accumulation of pathogenic
bacteria between crown edges and the gingival crevice. This leads to dental calculus formation and oral mucosal inammation.
When it comes to tooth care, most people usually concentrate on the tooth “whiteness” and do not pay attention to healthy
gum condition. Meanwhile, if interdental spaces and gingival crevices (areas between the tooth neck and gums) are not
cleaned regularly, it leads to gradual growth of dental calculus, gingival inflammation, and persistent foul breath. As the in-
flammatory process develops, gingival tissues gradually get detach from the tooth, which allows bacteria to penetrate deeply,
even reaching the jaw-bones, which is also subject to inflammatory destruction.
Due to bone tissue reduction, gingival decay also starts: visible tooth elongation appears, and the smile looks less aesthetic.
Reduction of tooth embracing by the gum and also the weakening of bone tissue support lead to tooth loss.
AQUAJET portable oral irrigator is necessary for treatment and prevention of such diseases.
Portable Oral Irrigator AQUAJET LD-A3
Instruction Manual

6
ENG
The special nozzle structure allows the water-jet to reach areas inaccessible using a simple toothbrush or dental floss.
Powerful pulsating water head washes out food debris and soft dental plaque, preventing the formation of hidden decay
cavity, massages gums and the whole oral cavity, promoting the blood supply. This helps to prevent periodontal disease,
inflammatory periodontal processes, and tooth decay.
INTENDED USE
AQUAJET Portable oral irrigator is intended for treatment and prevention of periodontal diseases, gingivitis, periodontitis;
for medical irrigation and for the massage of the oral cavity, and care for dental appliances (including crowns, implants,
prosthetic dentures, occlusion correction devices) and interdental spaces.
AQUAJET usage for oral hygiene cannot substitute the toothbrush completely. Use AQUAJET after meals to wash out food
debris and to provide deep gingival massage. Do not forget to clean your teeth with a toothbrush after using AQUAJET.
According to the periodontal disease studies, early stages of dental calculus formations are often ignored because of lack
of overt signs. Such diseases usually progress to more severe stages. Gingival bleeding after AQUAJET usage is a symptom
of periodontal disease. However, prolonged AQUAJET usage leads to the relief of this symptom and allows to restore a
healthier gum condition. Consult your dentist if the bleeding continues for more than two weeks.
Potential consumers: all people older than 2 years.
Functional features: using a powerful pulsating water-jet, the device removes food debris from interdental spaces and
other difficult areas in the oral cavity, massages gums, improves the blood flow, and prevents gum bleeding. It provides
maximum care for prosthetic dentures and crowns, prevents the development of pathogenic bacteria and inflammatory
processes in places of prosthetic denture and crown interface with the oral mucosa, which is not achieved by other common
means. It prevents the formation of dental calculus, gingivitis, and many other periodontal diseases.
Compact size and power supply from a self-contained battery allow the usage of the irrigator while travelling. The battery
is charged from the power supply (PS) or another source equipped with a USB-port and corresponding to the characteristics
defined in the section “Technical characteristics”.
Use of AQUAJET Irrigator by Children
Device usage by a child is allowed only under the surveillance of an adult who has thoroughly read this Operation Manual.
Irrigator usage by children decreases the risk of dental diseases, facilitates oral care, and shortens oral hygiene time
significantly in case of brace wearing. Children also often lack patience and diligence for thorough tooth cleaning, while the
irrigator usage provides the best oral hygiene possible.
Children may start using oral irrigator when they can use the toothbrush independently.
Though correct usage of the oral irrigator cannot traumatize the oral cavity, pay a visit to the pediatric dentist before using
the irrigator.
Device usage by a child is allowed only under the surveillance of an adult who has thoroughly read this Operation Manual.

ENG
Use
Bend over the sink. Bring the nozzle tip to the teeth or gums. Keep your mouth slightly opened, so that the water can
pour into the sink. Direct the nozzle perpendicularly to farther teeth of the lower dental arch. Turn on the device, switch-
ing the mode switch 1.3 to position «» (average pressure) or to position «» (strong pressure).
Slowly and carefully, clean the interdental space for 4-5 sec., holding the jet near your gums. Then swipe the jet along the
gum line near the tooth base to the next interdental space. Repeat the same movements as for the first interdental space (Fig.
16: dashed arrow indicates the place of water jet application, solid arrow – the nozzle movement direction).
You can stop the jet at any time, switching the mode switch into the position «» - Off.
Do not direct the jet directly into the gum pocket; try to hold the jet perpendicularly to the tooth line.
Perform the same procedure for all interdental spaces from external and internal sides of the lower tooth arch. Then repeat
the procedure for external and internal sides of the upper tooth arch. (Fig. 17)
If artificial orthopedic structures are present in the oral cavity, their places of contact with gums, teeth, or other dental
appliances should be rinsed with a jet more thoroughly. It is recommended to consult the dentist on the features of existing
rinsing channels in these structures.
Always empty the water from the container after usage. This prevents bacteria from multiplying.
Switch off the device by switching the mode switch 1.3 into the position «», remove the nozzle, the container, and the
tube. Rinse everything under warm tap water and wipe them with a dry cloth. For convenient storage and transportation,
put the accessories into the included container and connect it to the main unit (Fig. 13).
