title: Salivary function and glycemic control in older persons with diabetes.
abstract: OBJECTIVE
  There is no consensus on the possible association between diabetes and salivary dysfunction in older persons with diabetes. This study's purpose was to investigate the effect of diabetes and glycemic control on salivary function in an older population.
  
  
  METHODS
  Twenty nine persons with type 2 diabetes and 23 nondiabetic control subjects participated (age range, 54-90 years). Diabetic status was determined by a glycosylated hemoglobin (HbA(1c)) test and a 2-hour glucose tolerance test. Poor glycemic control was defined as HbA(1c) >9%. Unstimulated whole saliva, unstimulated parotid, and stimulated parotid flow rates were measured, and subjects completed a standardized xerostomia questionnaire.
  
  
  RESULTS
  Persons with poorly controlled diabetes had lower (P =.01) stimulated parotid flow rates than persons with well-controlled diabetes and nondiabetic control subjects. There were no significant differences in xerostomic complaints based on diabetic or glycemic control status or salivary flow rates.
  
  
  CONCLUSIONS
  These results provide some evidence that poorly controlled diabetes may be associated with salivary dysfunction in older adults who have no concomitant complaints of xerostomia.
