The effects of ultrasound on the wound healing process after teeth extractions were studied histologically. The right upper incisor was extracted in 56 rats. They were divided into 2 groups, one control (I) and one experimental (II). Group II received ultrasound stimulation that was applied with the frequency of repetition of 1,000 Hz and pulse length of 2,000 us continuously, during five minutes daily since the extraction day until 24 hours before the death. The rats were sacrificed at 3, 6, 9, 12, 15, 18, and 21 postoperative days. The results showed a precocious granulation tissue formation, faster remodeling of osseous ridges, and consequently acceleration of the alveolar wound healing process.
通过组织学研究了超声对拔牙后伤口愈合过程的影响。对56只大鼠拔除右上切牙。将它们分为2组，一组为对照组（I），一组为实验组（II）。实验组（II）从拔牙日起至处死前24小时，每天持续5分钟接受频率为1000Hz、脉冲长度为2000微秒的超声刺激。在术后第3、6、9、12、15、18和21天处死大鼠。结果显示肉芽组织形成早熟，骨嵴重塑加快，从而加速了牙槽伤口的愈合过程。
