Differences in the oral health status and oral hygiene practices according to the extent of post-stroke sequelae

Abstract

Oral health and hygiene are crucial parameters in stroke patients. However, few studies have evaluated the oral health status and oral hygiene practices according to the level of function in stroke patients. The aim of this study was to evaluate the oral health status and oral hygiene practices according to ambulation and personal hygiene levels in patients with stroke. Data from the fifth (2010-2012) and sixth (2013-2015) editions of the Korea National Health and Nutrition Examination Survey (KNHANES) for 6 years were combined. A total of 700 stroke patients were enrolled in our study. Subjective oral health was significantly poorer in patients who experienced a moderate problem with walking (adjusted OR [AOR], 1.68; 95% CI, 1.21-2.33) and bed-bound patients (AOR, 2.92; 95% CI, 1.01-8.44) than in patients who could walk without difficulty. Patients who were unable to bathe or dress independently exhibited a significantly higher risk of dental caries than did those who could perform the same activities unassisted. The probability of brushing teeth ≥2 times daily was 69% lower in bed-bound patients (AOR, 0.31; 95% CI, 0.11-0.87) than in patients who could walk without difficulty and 76% lower in patients who were unable to bathe or dress independently (AOR, 0.24; 95% CI, 0.09-0.62) than in those who could perform the same activities without difficulty. There were differences in oral health status and oral hygiene practices, according to ambulation level and functional independence, in the stroke patient group. These results indicate the need for oral care for stroke patients who exhibit ambulatory and functional limitations.
