The items which proved to be significant, included the number of remaining teeth, the ability to rinse, communication, ability to dress/undress, ability to transfer, and eating (Fisher's exact test). A multiple stepwise logistic regression analysis showed that the nonuse of dentures was significantly related to dressing (qdentures was also related to the number of remaining teeth and to the disability of hand and oral functions.
