HYGIENE OF DENTAL UNITS

Discover XO’s infection control concept and maximize the safety of your treatments.

Prevention of cross-contamination is a crucial daily operation for any dental practitioner. The effectiveness of cleaning is enhanced through easily accessible dental equipment components and automatized procedures. Furthermore, the parts that are subject to intensive cleaning must be durable and maintain their functionality over many years of demanding use.

XO CARE’s infection control concept is simple but effective: we reduced the number of elements that dental professionals need to touch to a minimum. Elements which must still come into direct contact with the hands have to be easy to detach, clean, disinfect and, preferably, to autoclave.

We understand that managing asepsis procedures related to your dental equipment should not be a time-consuming process. Therefore, the solutions we have developed enable fast cleaning and automation of many manual infection prevention procedures. In this way, we deliver you high efficiency and maximize the time you spend treating your patients. You can rest assured that everything is as clean as it should be.

HANDS-FREE OPERATION

XO dental units are foot controlled. During the treatment, the practitioner does not have to use their hands to change instrument settings or adjust the position of the chair, etc. This significantly reduces the risk of cross-contamination.

ANTIBACTERIAL PAINT

The antibacterial paint on metal elements prevents the growth of bacteria and fungi on the surfaces of the unit. The antibacterial qualities of the paint were obtained by incorporating silver ions into the paint’s structure. The germ-destroying properties of the silver ions are activated by moisture in the air.

The paint successfully prevents microbial growth by:

  • blocking primary cell metabolism
  • stopping cellular respiration
  • preventing cell division

Antibacterial properties are preserved in the paint over its lifetime, providing a continuous, long-lasting effect.

SMOOTH METAL SURFACES

XO units have smooth and easy-to-clean surfaces. The unit covers are made of aluminum, which guarantees long-lasting color and surface smoothness, even after many years of rigorous cleaning.

EVERYTHING YOU TOUCH IS EASY TO CLEAN AND AUTOCLAVE

All parts that come into direct contact with the practitioner’s hands or instruments can be cleaned in a thermodisinfector and/or sterilized in an autoclave.

Most of plastic and rubber parts can be cleaned in the thermodisinfector at 90⁰C and autoclaved at max. 134⁰C.

The cuspidor bowl parts, cup holder, suction filters and instrument suspensions can be thermodisinfected at 90⁰C.

DENTAL UNIT WATER QUALITY

In general, the waterlines of a dental unit can be colonized by microorganisms like bacteria, fungi, and protozoa, forming a biofilm1-4. Regular disinfection of waterlines prevents the growth of these microorganisms and the formation of biofilm.

XO Water Clean constantly decontaminates the unit’s waterlines by dispensing a small dose of peroxide into the treatment water.

Furthermore, the system offers both daily and occasional procedures for the disinfection of waterlines. During the daily procedure, the water is completely drained from the unit for the night, followed by disinfection of the water system in the morning. An alternative, occasional procedure is recommended after longer periods without usage of the unit.

XO Water Clean has been proven to maintain high water quality over the lifetime of XO units.

XO SUCTION DISINFECTION

It takes less than 1 minute to start the automatic process of disinfection of the suction tubes. Throughout the process, the suction tubes are flushed with a disinfectant and completely dried out.

EASY CLEANING OF SUCTION FILTERS

Suction filters on XO units are easily cleaned without touching the filter. Simply press the button to eject the suction filter.

AUTOMATIC CHIP BLOWER

When you stop the rotation of a turbine, the rotor blades which are still spinning, create a vacuum and may suck liquids from patient’s mouth into the turbine. To prevent this issue, the XO 4 unit will blow a small amount of air after the turbine is stopped.

Similar situation occurs when working with a micromotor with water. When you stop the rotation of an instrument the water valve is immediately closed as well. The water which is still flowing creates a vacuum just after the water valve. Once the water loses its fictitious force, the pressure of the vacuum sucks back the water along with liquids from patient’s mouth. Automatic, powerful chip blower on XO units blows out all the remaining water and prevents the retraction of liquids into the instrument.
