title: Dental dolorimetry for human pain research: methods and apparatus.
abstract: Electrical stimulation of human tooth pulp provides a means of safely producing human pain in the laboratory. This paper describes a dolorimetry and data collection system for stimulating volunteers, recording responses and analyzing data. The system allows multilevel stimulation in pseudorandom sequences and analysis of results using the methods of Sensory Decision Theory. It consists of modified commercial equipment, specially designed circuitry, an interface, and a programmable calculator. Fundamental problems and safety considerations for electrical dental stimulation are reviewed. Reliability of stimulation and response measurement is discussed.
