Cross contamination through dental chair


One of the most important aspects of the dental office is treatment unit (dental chair) because good dental chair plays important role in prevention of cross contamination during treatment. There are several things that has to be taken into consideration.  Some of these considerations are, it should be free of bacteria and germs prior to each treatment. Water coming through treatment unit into the patient’s mouth should be clean. Suction unit should be such that it should prevent cross contamination. To prevent tissue damage, the equipments used in the treatment units should produce less heat. Last but not the least; it should be comfortable to patient and dentist.


So the patient should be aware of all these things and inquire before getting treated.

Chair should have a turbine unit that provides protection mechanism against back suction phenomenon which prevents the back suction. Also it maintains quality of water(RO) coming through the treatment unit.

Following are some of the diseases which can spread through cross contamination during dental treatment. Saliva is considered to be one of the most common mediums that diseases choose as their mode of spread.
