Sterilization of Dental Equipment

The times are trying enough without having to worry about a visit to the dentist. There is much talk about the transmission of disease in any given medical environment. Well, we're here to say dentistry in our practice still is a safe and healthful experience. And it's not just a matter of trust.

It took the AIDS epidemic to bring it to the public eye. But we've been guarding against it at our dental office since the day we opened our doors.

I'm talking about communicable disease. AIDS is the one you hear most about, but there are others. A quiet new killer (HCV, hepatitis C virus) currently infects about four million Americans who will never be able to rid themselves of it. Here at the office we're also aware that hepatitis B, tuberculosis, influenza-even the common cold-are communicable. The good news is that the same strict standards of asepsis (cleanliness) we use against one disease also defend us against all the others.

You may not be aware of all we do to ensure your protection from cross-communicated viruses during your dental care. In fact, it's a large part of our day, and we're committed to the task.

We use disposable items wherever we can. Every surface in the operatory is secured against airborne bacteria with physical barriers. Our sterilization procedures are complex, monitored by an outside agency, and, not incidentally, much more than OSHA, the American Dental Association, the Centers for Disease Control, and local agencies require.

Metal instruments are cleansed in an ultrasonic bath before autoclaving in chemical pressurized heat. Hand pieces, for instance (you know them as drills), take an hour's preparation-heat-treated then cooled-for each patient. We disinfect everything in sight.

All this costs, but it's worth it.

We wouldn't be here if we didn't care about you, your health, and your good looks. We want you to feel comfortable, all the time. Please ask about our sterilization program and we'll be more than happy to show you what we're doing.

You know we care about open communication in our dental office. This letter is another way we hope to show it.

Dental Waterlines

Have you heard about biofilm? Our dental office monitors it daily. Possibly you'll catch something on TV about biofilm as some sort of newly discovered health threat. It's neither, really. Here are the facts:

Most of our dental equipment is connected to long, flexible tubes that deliver water to your mouth. We call these tubes dental waterlines. Every day, fresh water rushes through them. But overnight or over the weekend, water trapped in these long tubes has the potential of being colonized by a thin layer of microorganisms.

Those microorganisms are biofilm. It's just as important we keep our waterlines free of biofilm as it is you keep your teeth free of plaque through regular brushing.

We've known about biofilm for years. Every morning, all our waterlines are cleared before the first patient arrives. Our dental chairs are equipped with check valves that make sure waterline delivery goes only one way-into the mouth and down the drain.

All this to combat a health hazard that is so far only theoretical-we have no evidence of illness related to water from a dental waterline. Even if it existed, the marginally higher bacteria counts wouldn't necessarily pose a hazard to healthy patients. Bacteria is everywhere-in drinking water, the air we breathe. Getting rid of it is the job of our immune systems.

News organizations love to discover what they believe to be health threats, because it keeps viewers tuned in. But biofilm (if it exists at all) is something we've known about and protected patients against for years.
