Study information
Scientific title
The effect of improved oral prostheses on the nutritional state of elderly edentulous individuals: a randomised controlled trial
Acronym
SIN II
Study hypothesis
Null Hypothesis:
That there will be no difference in nutritional status measured by serum homocysteine levels in elderly edentulous males and females wearing mandibular 2-implant overdentures and those wearing mandibular conventional dentures at six months following delivery of the prostheses.
Ethics approval
McGill University Faculty of Medicine IRB, original approval received November 15, 2002; renewed yearly; latest renewal approved 29 August 2006 (study number A08-M75-02B).
