Feeding problems due to impaired oral motor functions resulting in prolonged meals are common among persons with brain damage. The aim of the present investigation was to study the oral sugar clearance in 16 individuals with oral motor dysfunction (OMD) and 16 individuals with normal oral functions (control group). Repeated saliva samples were collected on filter paper discs at two locations before and during 30 min after intake of a glucose tablet. The individuals with OMD had significantly higher initial glucose concentrations in saliva and longer glucose elimination time compared to the control group. For some of the subjects with OMD, sugar clearance was extremely slow. The sugar clearance time was positively related to the severity of drooling problems, but not to the degree of dysphagia. The results from this study indicate that individuals with OMD have an increased risk of dental caries.
