Changes in oral health status with dental intervention during the acute to subacute stages of stroke

Abstract

ObjectivesTo investigate the changes in oral health status with dental intervention during the acute and subacute stages of stroke and their associations with oral intake status.BackgroundOral health may deteriorate easily in patients following a stroke. However, data are scarce on the changes in oral health with dental intervention throughout the acute and subacute stages of stroke recovery.Material and MethodsWe prospectively recruited 98 stroke patients who were admitted to an acute hospital and referred to a dental team and then could be followed at a subacute rehabilitation unit in the same hospital. Provided dental intervention, including oral health care and other general dental treatments, was recorded. Oral health was assessed with Oral Health Assessment Tool (OHAT), and the changes in OHAT score during the acute and subacute stages were statistically tested. Oral feeding status was examined using Functional Oral Intake Scale (FOIS). The cohort was divided into the non‐oral feeding, dysphagia and regular diet groups based on FOIS score. Differences in OHAT among the oral intake groups were statistically tested.ResultsGross OHAT score did not differ among the oral intake groups at the time of admission (mean ± standard deviation score: 6.5 ± 2.8 for non‐oral diet, 5.6 ± 2.4 for dysphagia diet and 5.3 ± 2.1 for regular diet), but improved more in the regular diet group (2.4 ± 1.5) than in the other groups (5.8 ± 3.0 for non‐oral diet and 4.0 ± 2.1 for dysphagia diet) at the last evaluation. Oral hygiene scores improved significantly in the acute stage, while scores for dentures and natural teeth ameliorated significantly in the subacute stage.ConclusionOur findings suggest that appropriate dental intervention in the acute and subacute stages of stroke may contribute to improved oral health and oral food intake.
