The purpose of the investigation was to compare the absorption effectiveness of a novel dental absorption roll (DAR) (containing sodium polyacrylate) to a traditional dental cotton roll (TCR). 160 traditional cotton rolls (TCR) were used for the assessment as well as 160 DAR rolls to achieve ten sets of data for both DAR and TCR. The DAR was constructed from nonwoven cotton material sachet containing sodium polyacrylate polymer in the core and weighed 0.32 grams. The total weight of the traditional cotton roll used in this study was 0.5g. All the absorption rolls in the test (DAR) and control (TCR) groups were individually submerged into a beaker of distilled water (200ml at 37ºC) for predetermined time intervals, ranging between 1 and 60 seconds. The DAR or TCR were secured carefully in stainless steel locking tweezers and submerged in the distilled water. The Mann Whitney test was performed on the results obtained from the mean values of the respective specimens. The absorption of the DAR was significantly higher (Mann Whitney test), being 7.18 (SD=0.23) ml in comparison to 3.23 (SD=0.17) ml of the TCR at the 60 second time interval. The DAR absorbed 22 times its own weight and TCR only 6 times its own weight at the 60 second time interval. The DAR was significantly more effective in absorbing the distilled water 7.18ml (SD=0.23) after 60 seconds compared to the TCR 3.23ml (SD=0.17).
