A Fundamental Study on Assessment of Gingival Blood Flow

The purpose of this study was to establish the assessment of gingival blood flow by laser Doppler flowmeter (LDF) using three parameters; Velocity, Volume, andFlow. The gingival blood flow (GBF) at the labial attached gingiva of the maxillary incisor was measured by LDF in 10 healthy subjects, 3 men and 7 women. There were inter—and intra—individual variations in the obtained data. CV (coefficient of variance) values in each parameter of GBF while resting were as follows; Velocity: 10.2-34.5%, Volume: 7.7-45.6%, andFlow: 15.4-67.6%. The effects of changing position, cold stimulus, and the vasoconstrictor (0.1w/v% epinephrine) on GBF were assessed. All three parameters significantly decreased (p
