Effects of bleaching on laser Doppler blood-flow signals recorded from human teeth in vitro

Highlights • The effect of bleaching a tooth on laser Doppler recordings of pulpal blood flow was studied. • Recordings were made while extracted teeth were perfused with blood. • Blood was pumped through a cannula in the pulp cavity before and after bleaching. • At each perfusion rate the flux incr...

Description
Summary:Highlights • The effect of bleaching a tooth on laser Doppler recordings of pulpal blood flow was studied. • Recordings were made while extracted teeth were perfused with blood. • Blood was pumped through a cannula in the pulp cavity before and after bleaching. • At each perfusion rate the flux increased by an average of 46% after bleaching. • It is impossible to determine the effect of bleaching on pulpal blood flow in vivo.
