A dental instrument system has an optical component with a mirror for the dental practitioner to view a patient's mouth. A light source and an airflow source have a plurality of output levels that are controlled by a user input on the handle, such as a single button. The output levels of the light and airflow are controlled by a single or double click, wherein a single click increases the output level of the airflow and a double click increases the output level of the light, for example. The light source illuminates the mirror and the airflow source produces airflow over the mirror to remove debris and bodily fluid. A clearing flow of air may be initiated by holding the single button down on the handle and release of the button may return the airflow to the previous level.

A dental mirror includes a handle having a lumen, a mirror housing attached to the handle, a mirror cartridge for insertion through a cartridge opening of the mirror housing, a drive shaft rotatably held within the handle, and a film-roller rotatably attached to a film-roller bearing. The mirror cartridge includes a base, a film-roller bearing connected to the base, a film support structure connected to the base, and a film surrounding the film support structure. A distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure.

Provided are methods of immunizing a viewport of a medical device against fogging before or during a medical procedure, and related apparatuses and devices. The methods comprise applying plasma to the viewport prior to use, thereby rendering a surface of the viewport highly hydrophilic. The methods eliminate or at least significantly reduce blur due to fogging.

A protective sleeve comprises a housing configured to fit over a portion of an intraoral scanning device and protect the intraoral scanning device from an external environment. The intraoral scanning device comprises a first aperture for transmission of optical signals, the housing defines a second aperture for transmission of the optical signals, and the second aperture is aligned with the first aperture when the housing is fit over the portion. The protective housing comprises one or more supports attached to the housing and a transparent element secured by the one or more supports and aligned with the second aperture. The transparent element is further aligned with a defogging element of the intraoral scanning device when the housing is fit over the portion, and an external surface of the transparent element is to receive heat generated by the defogging element to prevent fogging of the transparent element.

An endoscope comprising a lens, and an anti-fog film, wherein an optically clear adhesive bonds the anti-fog film to the lens or lens section.
