Oral Health-Related Quality of Life in Patients after Stroke-A Systematic Review

Objectives: Aim of this systematic review was to assess oral health-related quality of life (OHRQoL) of patients after stroke. Methods: The systematic literature search was performed on December 2021 based on PubMed, Medline, Web of Science, and Scopus, with the search terms: "oral health-related quality of life" AND stroke OR apoplexy OR ischemic stroke OR apoplectic insult. Articles exclusively examining patients after stroke and reporting a well-documented and valid OHRQoL measurement were included. Results: Out of 68 findings, 8 studies were included. The number of patients ranged between 31 and 549 individuals, mean age between 55.7 and 73.9 years, and 49-72% of individuals were male. Two studies included a healthy control group. Oral health parameters were rarely reported across studies. Five studies reported on the Oral Health Impact Profile (OHIP) 14 for OHRQoL, showing means between 2.87 and 33.0 in sum score. Three studies applied Geriatric Oral Assessment Index (GOHAI), with sum scores between 45.6 and 55.0. Only one study found worse OHRQoL in stroke patients compared to healthy controls. Two studies reported on an association between OHRQoL and general quality of life. Three studies found OHRQoL to be associated with different oral health parameters. Only one study found OHRQoL to be associated with stroke-related parameters. Conclusions: Patients after stroke show a reduced OHRQoL. Medical staff and caregivers should support oral hygiene and dental visits, to foster patients' oral health and OHRQoL.
