Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome(s) as of 13/02/2026: 1. Changes in translucency of retainer polymer are measured using a spectrophotometer at baseline and 6 months 2. Changes in colour of retainer polymer are measured using a spectrophotometer at baseline and 6 months 3. Changes in surface roughness of the retainer polymer are measured using a profilometer at baseline and 6 months 4. Changes in the flexural strength of the retainer polymer are measured using a universal testing machine at baseline and 6 months 5. Comparison of prices for the thermoplastic retainer cleansing agents (Toothpaste, Retainer Brite, and Tap water) is measured using a monthly price survey. The prices for cleanser products, including over-the-counter, health sectors and virtual through official online purchasing websites, such as Amazon, Shopee and Lazada. _____ Previous primary outcome(s): 1.
