Sterile dental office at DentClinic

Why sterility is critical

In dentistry, the doctor works with blood and saliva — so any error in sterilization can lead to infection transmission: hepatitis, HIV, herpes. Unfortunately, many small clinics cut corners precisely here — because proper sterilization is expensive and time-consuming.

At DentClinic we built our process according to the EN ISO 17665 protocol — the European standard for medical institutions. Every instrument goes through 5 processing stages and cannot be used without confirmed sterility.

Important You can ask the administrator any time to show you the sterilization room and verify the process quality. We are open about it and proud of it.

How we sterilize instruments

Stage 1. Disinfection

Right after the procedure, instruments are placed in a solution that kills most bacteria and viruses. Safe for staff and instruments.

Stage 2. Ultrasonic cleaning

Ultrasonic waves clean the instrument from microparticles in hard-to-reach areas — where a regular brush cannot reach. Critical for complex tools: endodontic instruments, burs, scalers.

Stage 3. Packaging

Clean instruments are placed in individual kraft pouches with indicators. The indicator shows the instrument actually went through sterilization (and not just "sat in the cupboard").

Stage 4. Autoclaving

Sterilization with pressurized steam at 134 °C. Destroys all forms of microorganisms, including spores. We use class B autoclaves — the safest on the market (Melag, Germany).

Stage 5. Control and storage

Every autoclave cycle is verified with a biological indicator (weekly) and physical indicator (every cycle). Sterile pouches are stored in a closed cabinet until use — no longer than 6 months.

What we use as single-use

  • Gloves and masks — a fresh pair for every patient
  • Saliva ejectors and suction cannulas
  • Needles and syringes for anesthesia
  • Anesthetic carpules — individual, in sterile packaging
  • Endodontic files for canal treatment (for safety and precision)
  • Patient cups and bibs
  • Protective films on the lamp, handles and unit buttons

What we do additionally

  1. UV office disinfection. After each patient the office is irradiated with a UV lamp — kills viruses in the air.
  2. Autonomous water supply. Distilled water is supplied to the dental unit, not tap water — to eliminate infection risk.
  3. Regular checks. The Ministry of Health laboratory takes samples quarterly — required for all clinics, and we always pass without remarks.
  4. Staff training. Each employee takes an annual infection-safety course.

Frequently asked questions

Can I see how instruments are sterilized?
Yes, of course. We are happy to open the sterilization room for patients. Just tell the administrator and we'll show you everything before your appointment.
How do I know my instrument is sterile?
Before starting, the doctor opens the sterile pouch right in front of you. If the indicator on the pouch hasn't changed color — the pouch is not used.
Can I bring my own instruments?
No, unfortunately. We cannot guarantee the sterility of an instrument that wasn't processed by us. But we do guarantee the sterility of our own instruments — and take full responsibility.
What about patients with HIV or hepatitis?
We accept all patients, and our sterilization standard does not depend on diagnosis — it's equally high for everyone. That's the whole point of universal protective measures.
