As documented here before, I am a big fan of isolation techniques. I am a rubber dam believer and still use it in my practice. I also use an Isodry in my practice. An article in the March 2011 issue of JADA compares temperature and humidity of mouths when different isolation methods are in place. The study compared rubber dam, Isolite I2, Coolex, and no isolation. All three methods decreased the temperature and relative humidity intraorally. Rubber dam decreased both the most, but there was a very little difference between the rubber dam, Isolite, and Coolex. This study definitely emphasizes the importance of dry0field isolation techniques. All three of these systems work far better than nothing. A rubber dam is obviously the cheapest of the options, but both the Isolite and Coolex are affordable and offer a good value for the ease of use. I know I could not practice without my Isodry. If you have had issues with isolation, I would definitely look into this study and these methods. They will help improve your dentistry!
