Abstract
Laser Doppler flowmetry was used to study the microvascular blood flow of the human gingiva. Power spectral density analysis of the Doppler signals indicated differences in the vascular structure/flow patterns in four tissue types that were studied. Cigarette smoking elevated the gingival blood flow during a 5-min period after which the flow came back to baseline values. The study indicates that the laser Doppler method is a convenient and noninvasive method for dynamic blood flow measurements in the gingiva
