Objective: This study was performed to evaluate the ability of four different electric power toothbrushes to remove dental plaque on a three-dimensional (3-D) study model. Methods: A 3-D, 360-degree model of 32 human teeth was made of polyester (ELEGOO Inc.). Then, eight photos were made (four teeth at a time) from each quadrant and used as the negative control group (0% plaque). Then plaque-like color spray chalk were added and cured on the teeth model; photos were made and used as the positive control group (100% plaque). The 3-D model of the teeth was placed on a rotatable axis and immersed in a basin mimicking the composition of artificial saliva and toothpaste. An apparatus with a mechanical arm was made to hold the toothbrushes during the plaque removal process and control the force of brushing. Twenty-four toothbrushes were prepared and divided into four experimental groups of 6 (n=6) including 1) Philips, 2) Oral-B, 3) Quip, and 4) Waterpik. Toothbrushing was performed for 2 minutes. After brushing, photos were taken, and the percentage of plaque removal was measured by using the ImageJ software. Data were analyzed by Kolmogorov–Smirnov, ANOVA, and post hoc Tukey tests. Results: The highest plaque removal values were observed in the Philips group, and the lowest were seen in the Quip group. Significant differences were only recorded between the values of Philips and the other groups (p<0.05). Conclusion: Within 2 minutes of brushing time, none of the power toothbrushes could completely remove artificial dental plaque.
