Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

The present disclosure is directed to systems and methods for electronic control of an operating level of an oral irrigator, particularly when flow from the oral irrigator is paused. Methods for controlling an operational level include: determining an operational level of the oral irrigator, including whether the operational level is a standby mode; receiving sensor data from one or more sensors; determining whether a key sensor indicator is above, below, or at a threshold. If the key sensor indicator is above a threshold, the operational level is changed to standby mode. If the key sensor indicator is at or below the threshold, the operational level remains at the current level. If the key sensor indicator is below the threshold, and the current operational level is the standby mode, the operational level is changed to the operational level set before entering standby mode.

The present disclosure provides a double-tank oral irrigator. The double-tank oral irrigator includes a rotary valve, a first tank, a second tank, a water guide pipe, and a pump assembly. The rotary valve includes an outlet part, a first inlet part, a second inlet part, and a valve core. The rotation of the valve core enables adjustment of the sealing degree of the valve core to the first inlet part and the second inlet part. The first inlet part is connected to the first tank, the second inlet part is connected to the second tank, and one end of the water guide pipe is connected to the outlet part. The pump assembly is connected to the other end of the water guide pipe and a spray outlet of the oral irrigator.
