Oral health and oral health-related quality of life among older adults receiving home health care services: A scoping review

Abstract

Objective: To map the literature on subjective and objective oral health indicators and oral health-related quality of life (OHRQoL) in older adults receiving home health care services (HHCS). Background: The proportion of older adults in need of HHCS will increase in the coming years. Previous studies indicate that frail and dependent older adults are at increased risk for oral diseases, due to challenges with daily oral hygiene and regular access to dental services. Materials and methods: Four databases were searched in November 2020 for relevant literature. Search terms included a comprehensive list of terms for adults 65 years or older receiving HHCS, clinical and subjective oral health indicators, and OHRQoL. The literature was reviewed based on inclusion and exclusion criteria. Results: Of the 3114 sources identified, 18 were included. Data on oral diseases and symptoms among older adults receiving HHCS were limited and heterogeneous. Overall, older adults often lacked some of their natural teeth and often had removable dentures that needed repair. In addition, plaque, caries, xerostomia, and chewing and swallowing problems were common among the population group. Data on OHRQoL were scarce and indicated a positive association with a higher number of present teeth, while decayed teeth, root remnants, and dry mouth had substantial negative impacts on the daily activities of older adults receiving HHCS. Conclusion: This scoping review show that older adults above 65 years receiving HHCS generally have poor oral health status and that there is a knowledge gap regarding their OHRQoL.
