Beware of sterilization in dentistry!


Beware of sterilization in dentistry!


Turnover of patients in a dental office or a dental clinic space increases its microbial load. In addition, the use of rotary remote scattering leads to organic materials (dentin, saliva, blood) possibly contaminated with pathogens.

How to Decontaminate?

To prevent this risk, exposed surfaces are decontaminated, thereby reducing the number of germs to zero. The chemicals used for this purpose last generation, whose spectrum is very broad intervention and elimination, taking care also to observe shutter agent decontaminant.

Disinfectants used meet the mandatory European standards for disinfection and are antibacterial substances active on Candida albicans, fungicidal, sporicidal, virucidal active HIV, the hepatitis B and C, adenovirus, coronavirus, herpes virus type 1 and tuberculocidal active on Mycobacterium tuberculosis. For hand disinfection chemicals are used specific potent disinfectant before and after use examination gloves.

Sterilization of dental instruments

Dental Instrument Sterilization involves complex processes which totally destroys microbial flora (as vegetative and sporulated bacteria, viruses, fungi) on the materials undergo the process. Certainty of sterilization depends on the following steps: presterilizarea stage involving instruments in preparation for sterilization, and sterilization methods.

Presterilizarea instruments involves immersion in a bath of disinfectant that has cleaning properties after sterilization. Before this stage is done prewash and normal cleaning. After driving compliance optimum time of the disinfectant, the instruments are washed thoroughly with suitable brushes, insisting the joints, the grooves needles and drills, to remove all forms of organic matter. Pliers extraction and other surgical instruments are subject to the same stage of presterilizare but in separate containers, then dry and clean again if necessary.

After drying and verification tools are packed in tight sheets that have provided markers sterilization transferred (change color), thereby enabling optimal temperature control and display materials while allowing verification of sterilization. Also on metal boxes that are grouped with other tools such place marker bands sterilization, both inside and outside the box. In these markers, namely the single sheets are noted on day and time so that we can control the sterilization of instruments up to 24 hours before use. This can be checked daily and by mentioning a book sterilization of instruments subject to this process, thus the sterilization, instrument parameters, and next to that date sterilization adding marker inside the device.

Appliances are regularly checked and monitored by state institutions for this purpose certified by tests that check the parameters of each device. Referring to these devices, sterilization methods alone. Thus, instrumental dental sterilization is done by physical and chemical methods. The physical require dry heat (hot air oven sterilization - pupinel - at 180 degrees for 1 hour per day) and wet heat (steam pressure sterilization, autoclaving, where water vapor temperature increases with pressure, respectively 134 degrees for 45 minutes). Chemical methods of decontamination is done with disinfectants and antiseptic for surface disinfection and antiseptic hand. It should be mentioned attitude residue, there are special containers for this purpose, and provided with a tight little hole that are taken when filling a special service and incinerated. There are a number of disposable materials such as vacuum cleaners, foam (rolls, pads, sterile fields) etc.

All these measures lead decontamination certainly safe to remove any suspicion of risk of disease in the dental office.
