• Home refiner
• Experimental rake-up test
• Peel test with finger
• Shore E hardness
• Type of failure

The purpose of this study was to investigate methods for evaluating objectively the removability of three commercially available home refiners (Cushion Correct, Tafugurippu Pink A and Liodent Pink). After immersing each of the refiners in distilled water at 37 degrees C for 24 h, we compared their removability using the peel test with a finger, which was evaluated based on a visual analogue scale and the percentage of the residual area. An experimental rake-up test was also undertaken to quantify removability, evaluated based on the total amount of work required to remove it. The Tafugurippu Pink A product was easier to remove with a finger than the other two home refiner products, and required the least total amount of work to be removed in the experimental rake-up test. Furthermore, the rake-up test performed could possibly be used for objective evaluation of the removability of home refiner.
