Evaluation of the modifications occurring in human gingival blood flow following periosteal stimulation.
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 anesthetic containing a vasoconstrictor. Finally, 12 patients were subjected to GBF measurements before and 8 days after periosteal stimulation prior to gingival grafting.
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.
Periosteal stimulation induces significant increases in the GBF after 1 week.
评估骨膜刺激后人类牙龈血流的变化。
使用激光多普勒测量牙龈血流（GBF）。通过比较间隔1周进行的测量来验证该技术的可重复性。通过记录注射含血管收缩剂的麻醉剂前后的GBF来验证敏感性。最后，对12例患者在牙龈移植术前进行骨膜刺激前及刺激后8天的GBF测量。
激光多普勒能准确测量GBF。第0天和第7天的测量结果无统计学差异（p = 0.60）。注射含血管收缩剂的麻醉溶液后，激光多普勒记录到GBF急剧下降（p = 0.04）。接受骨膜刺激的患者在刺激前和刺激后1周GBF有统计学显著增加（p = 0.02）。
骨膜刺激1周后可导致GBF显著增加。
