Waterline contamination is a growing concern in dentistry. Water coolant is necessary during tooth preparation in order to avoid overheating of the tooth. Typically, the water used in this process is regular tap water. The purity of tap water varies across the country and within communities. Contamination in waterlines can involve the various chemicals put into community water sources as well as bacteria and viruses that may develop in the lines themselves. The country's water supply is generally considered to be safe. I am unaware of any health problems that have been attributable to waterline contamination. But in an effort to be pro-active, I have eliminated the use of community water supply as a coolant in operative dental procedures. Our new Adec delivery units utilize a water coolant completely separate from the community water supply. We use sterile distilled water in these new delivery units so that every operative procedure uses water coolant that is free from all contaminants. I am proud to be able to provide the latest in technology and exceptional service to my patients.
