Objectives: Evaluation of the modifications occurring in human gingival blood flow following periosteal stimulation. Material and methods: Laser Doppler was used to measure the gingival blood flow (GBF). The reproducibility of the technique was validated by comparing measures made at intervals of 1 week. Sensitivity was verified by recording GBF before and after injection of an anesthesic containing a vasoconstrictor. Finally, 12 patients were subjected to GBF measurements before and 8 days after periosteal stimulation prior to gingival grafting. Results: The laser Doppler accurately measured GBF. Measurements made at day 0 and day 7 were not statistically different ( p =0.60). After injection of an anesthesic solution containing vasoconstrictor, the laser Doppler recorded a sharp decrease of the GBF ( p =0.04). The patient that underwent periosteal stimulation showed statistically significant increases ( p =0.02) in GBF before and 1 week post‐stimulation. Conclusion: Periosteal stimulation induces significant increases in the GBF after 1 week.
