Electronic tooth stimulator for pain research

It is not possible to measure pain but it is possible to measure the stimulus that causes it. Electrical stimuli are probably the most suitable since they can be readily produced and accurately measured. Applying stimuli to the teeth of human subjects is convenient and does not cause damage. This paper describes a tooth stimulator which is considered to be an advance on other available equipment, being easier to use and more accurate, as well as reassuring for the human patient or experimental subject.
