A research study from the University of Glasgow published in the Journal of Hospital Infection appears to throw doubt on the safety of certain sterilization techniques available to dentists and recommends steam sterilization as the gold standard.
The findings
The results are alarming: Five non-vacuum bench-top sterilizers in use at general dental practices were tested. Sterilization cycle times ranged from 16 – 25 min, with plateau periods of 3·5 – 4·5 min at 134°C. The period over which temperature differences between the sterilizer chamber and the inside of the hand pieces occurred ranged from 0 sec – N/A, which meant that some hand pieces did not achieve sterilisation temperature during the whole cycle. In contrast, all hand piece types demonstrated either a CI or BI fail (or combination of both). In both studies the surgical hand piece and the chuck lever location was the type and location most likely to fail sterilization. Co-author Brian Kirk of Glasgow Dental Hospital wrote: "In conclusion, we report investigation of sterilisation process outcome using a unique combination of TM, CI and BI tests according to International standards. These test results demonstrate that the non-vacuum process is unreliable and fails to achieve sterilisation within dental hand pieces, especially surgical hand pieces that are commonly used in more invasive dental procedures such as dental implants."
An increasingly common procedure
With an increase in conditions such as peridontal disease this situation is bound to get worse over time. Is your dental practice using a good quality steam sterilization Autoclave? In a world of blame and claim, it seems increasingly important to do so.
Hi! I recently came across an Irish review of Lizaro casino no deposit bonus Ireland while researching various online platforms. I decided to take a closer look so I wouldn't jump to conclusions based solely on the name or website's appearance. It's convenient that it summarizes key points that you usually have to search for separately: mobile access, payment options, registration, identity verification, and customer support. For me, such reviews are primarily useful as a first point of reference—it allows me to quickly understand what issues I need to explore further. If you're also comparing options in Ireland, I would first look at a few similar materials and then check the current terms directly on the official website.
The electric pencil sharpener began chewing up pencils instead of sharpening them. I cleaned the blades, but it still jammed. I looked for alignment fixes and clicked a link in an office supply thread. It opened https://bongacams.com, but the streamer was demonstrating how to adjust the blade position. I followed their method, made a small tweak, and now it sharpens cleanly again. A completely surprising place for office tool advice, but it worked.
