A non-invasive dental or surgical monitoring system is disclosed. The monitoring system is comprised generally of dental or surgical equipment to be monitored, a main sensor unit, a set of sensors. The main sensor unit is in communication with various sensors removably attached to the equipment. The sensors monitor environment conditions related to the equipment rather than directly monitoring the equipment. The collected data is sent to the main sensor unit and can be accessed, or wirelessly transmitted by signal to a device or devices at another location. As collected data aggregates, a data profile can be created, machine learning can be used to discover patterns, and predictive analysis can be incorporated to help software make predictions of, or spot in real time, equipment problems based on deviations from the profile.

A dental mirror structure contains a body and a connector. The body includes an inspector, a connection segment, and a first air conduit. The inspector includes a lens, and the first air conduit has an inlet and an outlet adjacent to the lens. The connector is hollow and columnar, and the connector includes a second air conduit defined on a center thereof, a connection portion extending from a first end of the connector, a first stem extending from the connection portion, a second stem extending from a second end of the connector, and a fixing extension extending from the second end of the connector and surrounding the second stem. Thereby, the first stem is connected with an air supply element, the second stem is fitted with the inlet the body, and the fixing extension is connected with the connection segment.

A dental handpiece system includes a dental handpiece for operating a dental burr and providing a stream of water to the dental burr for cooling a tooth being acted upon by the dental burr. The dental handpiece further includes a flush water port for providing a flush water stream that is directed away from the dental burr to allow the dentist to flush a work site in a patient's mouth. The dental handpiece can also include an air outlet for providing a stream of air that is also not directed to the dental burr and that can be used to dry other dental instruments as well as work sites in the patient's mouth.

A cordless dental gas/water syringe is provided. The cordless dental gas/water syringe can be freely carried and operated by a dental practitioner within a dental facility. The cordless dental gas/water syringe includes a portable or wearable body. The body includes a water chamber, a water pump, a gas chamber, a gas valve, a water switch, a gas switch, and a conduit system for fluidic connection. The body can also include a controller including a touch panel and/or a button for controlling the gas switch, the water switch, the gas valve, and/or the water pump.

A method of preventing suckback of a dental handpiece and a dental handpiece system having a bypass injection structure are capable of effectively blocking a suckback phenomenon that occurs at the moment a rotating impeller stops. The method of preventing suckback includes bypassing air pumped from an air pump in a state where a flow path of an air supply pipe is blocked at the moment the impeller stops rotating and halts inside a head casing and injecting the air into the head casing through an air discharge pipe to block the suckback phenomenon.

An apparatus for endodontic treatment, comprising: a nozzle connected to a fluid source comprising: a tip small enough to be inserted into a pulp chamber of a tooth; an inner geometry which forms a flow parameters including non-axial flow direction of nozzle fluid flowing through the inner geometry such that discharge fluid discharged from the inner geometry increase rotation of root canal fluid within a root canal sufficiently to remove tissue from the root canal.
