Therapeutic and diagnostic endodontic device «EndoEst»

The EndoEst is digital therapeutic and diagnostic endodontic device created to perform the following tasks:

1) localization of root canal apical constriction (apex)

2) checking of a pulp vitality by stimulating it with weak current.

3) depot phoresis of hydroxide copper-calcium ions to tooth canals under the influence of electric current.

4) anode sterilization of a root by direct current.

5) pharmaceutical electrophoresis into root canal and periodontium

Available modes:

1. Apexlocator (АL) — localization of root canal apical constriction (apex):

• Multi-frequency principle of apex localization – guaranteed accuracy of measurements at any mediums;
• Digital, graphic, light and sound indication of measurement results.

2. Electroodontodiagnostics (PULP) – assessment of tooth pulp clinical condition:

Electroodontodiagnostics is based on the determination of tooth pulp pain and tactile receptors threshold excitation under their electric stimulation.

3. Depophores (DP) — copper-calcium depophoresis under methodic «HUMANCHEMIE GmbH»

Indications for the depophoresis procedure:

• Infectious processes in root canals, including roots of curved molars, upper wisdom teeth, obliterated canals and teeth covered with crowns;
• Periodontitis;
• Cysts;
• Osteolysis;
• Pulpitis (after pulp devitalizing)

4. Anode sterilization (AS) — root canal sterilization by direct current.

Interstitial fluid of root canal is used as electrolyte; electrolytic dissociation of which in the root canal causes chlorine release.

Therapeutic effect:

— Chlorine-therapy of the canal;

— Decontamination of canal and apical delta;

— Increasing of acidity in peri-apex.

5. Electrophoresis (ION) — pharmaceutical electrophoresis in root canal and periodontium

a) Hydroxyl (non-pharmaceutical) ionophoresis. Electrolyte — interstitial fluid of root canal.

Therapeutic effect:

— Antibacterial action of chlorine ions;

— Lysis of residual organic substances;

— pH normalization in peri-apex;

— Activation of calcination process at peri-apex area;

— Analgetic effect.

b) Pharmaceutical electrophoresis (with iodine, for example).

Electrolyte — saturated solution of potassium chloride in distilled water (2-3 drops) under L.R. Rubin methodic.

Therapeutic effect:

— Reduction of inflammatory processes in acute stage;

— Decontamination of root canal.

Additional functions of the device:

• Adjustment the volume level of the sound signal;
• Indication of the current accumulator charge level;
• Power-saving function.
