The dental unit cover is a practical protective accessory used to cover key parts of the dental chair or unit and create a cleaner barrier between the patient and the equipment. Depending on the set, it may include separate covers for areas such as the headrest, main body, seat or back section, and footer, with universal-fit options available for different chair models. It helps support infection-control routines, reduces surface contamination, and can also help prolong the service life of the dental unit in busy clinical environments.
