Abstract

A laser Doppler instrument has been designed for blood flow measurements in the human pulp. By using infrared laser light from a laser diode the penetration into the tooth is considerably improved in comparison with earlier He-Ne measurements. A hand-held, pen-shaped probe facilitates the clinical use of the instrument. Restricted blood flow conditions in trauma patients, as well as the heart-rate synchronous pulsating nature of pulp blood in normal subjects, have been investigated.
