Electric pulp tester
I got to use an electric pulp tester in the student clinics a couple of weeks ago and to be honest it was the first time I had used this since I myself was at dental school. I always saw it as cumbersome and anything that involves extra work is hard for me to take on board. I knew the theory that it was more useful in calcified pulps, but since graduation I have just tried the cold spray as a pulp test and if there was no response, I just shrugged my shoulders and moved on. I have found more success with using a cotton roll to soak the cold spray rather than a cotton pellet as it holds more cold and cover a larger surface area on the tooth.
