Aim:
We aimed to describe time requirements and costs associated with professional dental cleaning (PDC) performed by a dental nurse in one German nursing home, and to reveal potential differences in required time for demented versus nondemented and mobile versus immobile residents.
Methods And Results:
We performed a retrospective, cross-sectional analysis of treatment time and costs, including a transparent, easily adaptable path of action that allows implementation of PDC in nursing homes. Total mean (±SD) treatment time for one session per resident was documented, including differences in demented and immobile residents, and projected treatment costs (€/$) per resident. We found no differences in required time for one PDC (37 ± 11 minutes) in residents with or without dementia (P = 0.803) or, immobile versus mobile residents (P = 0.396). Mean projected treatment costs of PDC were €14.98/$17.07 per resident per cleaning session, resulting in total costs of €13.5 million ($15.4 million).
Conclusion:
Cognitive status and mobility does not affect the mean time required to perform PDC by a dental nurse in nursing home residents. Main cost factor is working time of dental staff; consumable supplies have less impact. Our data may stimulate to include PDC as initial step toward implementation of long-term oral hygiene strategies.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
