Abstract

This paper describes a new system in which optical reflectance is used to test the pulse and vitality of oral mucosa or dental pulp. Radiation at red (660 nm) and near infra‐red (850 nm) wavelengths are directed through a thin probe. The beam is directed into tissue and reflected back. Plethysmography is used to measure the pulse rate from the right forefinger. Reflected radiation is related to plethysmogram using a computer. Preliminary findings relating to the lips, and gingiva in 9 healthy volunteers were promising. Preliminary tests showed that vital and nonvital pulps reflected the radiation differently. Pulpal pulse did not always correspond to plethysmogram from the right Forefinger.
