Oral health measures included tooth loss, periodontal disease, self\u2010rated oral health, and self\u2010reported dry mouth. Participants were followed for onset of disability over a follow\u2010up period of 3\u2009years. Onset of disability was assessed through new cases of mobility limitations, activities of daily living (ADL), and instrumental activities of daily living (IADL).
