Development of the European Portuguese version of the oral health assessment tool: Content validity and reliability study in an elderly population.

Aims: Poor oral health is a risk factor for aspiration pneumonia (AP), especially in elderly patients at risk of oropharyngeal dysphagia (OD). In Portugal, available tools to screen oral problems in nursing homes are scarce. The oral health assessment tool (OHAT) is a screening tool that assesses elderly residents' oral health.
