Biofluorescence-guided oral care for hospitalized geriatric patient with pneumonia: A case report
Abstract
Effective detection and removal of pathogenic oral biofilm in hospitalized geriatric patient are important for preventing aspiration pneumonia. This case report describes the clinical application of biofluorescence-based technology for immediate assessment of oral hygiene status and biofluorescence-guided oral hygiene care in a hospitalized geriatric patient with pneumonia. The thickness and extent of oral biofilm were difficult to determine by visual inspection; however, biofluorescence imaging revealed red biofluorescence across multiple regions of the oral cavity. Based on these findings, mechanical and chemical biofilm control was performed at the bedside by a dental professional. Following oral care, the red biofluorescence observed before intervention was no longer present, allowing objective evaluation of biofilm removal. These findings suggest that biofluorescence enables real-time visualization of pathogenic biofilm and objective monitoring of changes in oral hygiene, improving the objectivity of oral hygiene assessment and supporting quality improvement in oral care for hospitalized patients.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
