LK-J11 Dental Endo Activator
1. Endo Activator sonic flushing
The vibration frequency of EndoActivator sonic irrigation equipment is low, can not produce cavitation effect, sound flow effect is weak, can not activate irrigation fluid, and apical overflow is less than ultrasonic irrigation. Different scholars have different results on the efficiency of removing calcium hydroxide in the root canal. Most scholars believe that Endo Activator's ability to remove calcium hydroxide in the root canal is better than that of syringe irrigation, and there is no significant difference from the ability of ultrasonic irrigation; while Topquoglu et al. believe that the efficiency of ultrasonic irrigation to remove calcium hydroxide is significantly better than EndoActivator's sound wave. There is no significant difference in the removal efficiency of Endo Activator sonic flushing and syringe flushing, Endovac system, and root canal brush. The efficiency of Endo Activator sonic flushing system for removing calcium hydroxide in the root canal remains to be further studied.
2. Ultrasonic washing
The high-frequency oscillation of the ultrasonic equipment can activate the irrigation fluid in the root canal to achieve the purpose of rinsing the root canal. Ultrasonic irrigation can produce cavitation effect, acoustic current effect and thermal effect, play a good sterilization effect, help to remove debris in the root canal, and promote the dissolution of organic matter.
It can improve the flushing effect of complex root canal system and reduce the adverse reactions caused by root tip overflow. A large number of studies have shown that ultrasound combined with irrigation fluid for irrigation has significantly improved the ability to remove the calcium hydroxide sealant in the root canal. Ultrasound can generate high-frequency vibrations to increase the flow rate of the irrigant and the efficiency of removing calcium hydroxide in the root canal. In the curved root canal, the ultrasonic tip (such as small
No. size file and smooth metal wire) can penetrate deeper into the root canal, even if the working tip can only reach the first bend of the root canal, it can effectively improve the removal efficiency of the root tip calcium hydroxide; but because of its rigidity The instrument may cut the dentin on the inner wall of the root canal, causing the root canal to shift. Therefore, in ultrasonic washing, a small ultrasonic working tip should be selected for shaking and washing at low power'.
