Scientific title | The effect of improved oral prostheses on the nutritional state of elderly edentulous individuals: a randomised controlled trial |
Study acronym | SIN II |
Study objectives | 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(s) | 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). |
Health condition(s) or problem(s) studied | Edentulism (lack of all teeth) |
Intervention | Control: Complete conventional dentures Experimental: Mandibular 2-implant overdenture with ball attachments and maxillary conventional denture |
Intervention type | Other |
Primary outcome measure | Serum level of homocysteine. |
Secondary outcome measures | 1. Patient satisfaction 2. Vitamin status 3. Changes in serum albumin 4. Changes in dietary habits 5. Changes in function 6. Cost effectiveness |
Overall study start date | 01/09/2002 |
Completion date | 31/12/2006 |
