在重要的牙髓治疗中，如直接盖髓，临床成功率取决于在暴露的牙髓组织中实现止血。对于暴露的牙髓组织，最常用的止血方法是用次氯酸钠湿润的棉球轻柔加压。然而，更快速和可靠的方法是必要的。因此，我们将重点放在高频无线电波（HRW）上。方法为了评价HRW对牙本质的修复诱导作用，我们建立了大鼠直接盖髓模型，用不同强度的HRW进行止血，并用氢氧化钙作为直接盖髓剂覆盖牙髓。14d和28d处死大鼠，观察牙本质和牙髓修复性炎症的组织学变化。结果与对照组相比，无线电波诱导止血所需时间短。HRW组牙本质修复，牙本质小管排列规律。结论shrw能诱导牙本质的止血，并能产生高质量的修复牙本质，减少牙髓炎症。
IntroductionIn vital pulp therapy such as direct pulp capping, clinical success rates depend on achieving hemostasis in exposed pulp tissue. For hemostasis of exposed pulp tissue, gentle pressure by cotton pellets moistened with sodium hypochlorite is most commonly used. However, more rapid and reliable methods are necessary. Therefore, we focused on high-frequency radio waves (HRW).MethodsTo evaluate reparative dentin induction by HRW, we used a rat direct pulp capping model and performed hemostasis by using HRW of several strengths, covering the pulp with calcium hydroxide as a direct capping agent. After 14 or 28 days, rats were killed, and reparative dentin and pulp inflammation were investigated histologically.ResultsRadio wave–induced hemostasis required less time when compared with the control group. Reparative dentin with regularly arranged dentinal tubules was observed in the HRW group.ConclusionsHRW induce hemostasis and produce high-quality reparative dentin and reduced pulpal inflammation.
