Method for treating a service water supply unit of a dental treatment unit, wherein the method has the following sequence of treatment steps: cleaning the service water supply unit using a cleaning agent, preferably a cleaning liquid or a cleaning foam; disinfecting the service water supply unit using a disinfecting agent, preferably a disinfecting liquid.

An oral care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having a transverse through hole defined by an upper surface and a lower surface. A first electrode and a second electrode are located on the head and operably coupled to a power source to have opposite electrical charges. At least one of the first and second electrodes may be located on one of the upper and lower surfaces of the transverse through hole. In some embodiments, the first electrode is located on the upper surface of the transverse through hole and the second electrode is located on the lower surface of the transverse through hole.

An apparatus and method for purging a dental air/water syringe comprises at least one of a button hold-down device for holding down at least one button of the syringe for discharging fluid therefrom and a collection container for collecting the discharged fluid. The button hold-down device includes axially spaced contact surfaces for contacting a syringe body and the button so that the device is supported mounted on the syringe body in a working position. The collection container features an interior perforated false bottom wall under which is formed a collection space where the discharged fluid collects, and a drain is communicated with the collection space for removing the collected fluid therefrom. The drain can be connected to a saliva ejector for removal of the fluid by suction.

Embodiments of the present invention are related to a patient protection apparatus with a first side, a second side, a back, a top and a front visor. The first side and second side each include at least one of a side arm aperture, an instrument aperture and an air filter interface. The back includes a plurality of back arm apertures and at least one back instrument aperture. The top has a wider length at the front of the apparatus and a shorter length at the back allowing the first side and second side to taper at an angle from the front to the back. Some embodiments include wheels for easy transportation and removable front enclosures. Other embodiments include smaller dimensions for ease of transport and more versatile application.

Disclosed is an assembly and method for fabricating a dental prosthesis, such as composite veneer directly in a mouth. The assembly includes a base that can be worn in a mouth, the base configured to fit around a base line. The base forms an enclosed body around teeth to be treated. The assembly further comprises a handle configured to secure to the base. The handle comprises an orienting arm that carrier a shell attach to its tip. The base and the handle are configured such as when the handle is secured to the base, the shell is placed over the tooth in a predetermined position.

One of the main problems of hoods and central ventilation devices for dental offices and clinics is the lack of fluid suction between the patient and the dentist during the spraying of the aerosol and droplet. This disclosure provides a solution to build a new device using technologies that follow the principles of ergonomics in designing and using the calculated discharge system to limit the movement of the aerosol and the droplet. This device proposes an isolation process whereby fluid transfer, along with the contaminated particles attached to the negative ions, are trapped in the chamber and transfer to the filter due, to prevent diffusion to the environment. This device also utilizes and control of optimal parameters of heat and light and negative ions, ultraviolet and ozone to sterilize and eliminate viruses and bacteria.

A computer-implemented dental charting system includes a computer storing tooth data for at least one patient and a display operable to display the tooth data. The computer is responsive to voice commands, and the display has a periodontal mode and a restorative mode. The display includes an exam overview window illustrating a plurality of tooth images, each tooth image corresponding to a patient tooth location, and an exam focus window. The exam focus window illustrates a magnified view of at least one of the plurality of tooth images, and illustrates data corresponding to the selected tooth location. The exam focus window may be displayed beside the exam overview window, as a floating window on top of the exam overview window, or on a physically separate display from the exam overview window.
