The study was to expand the choice of electric toothbrush by number of operations of the plaque removal effect on the tooth surface. Three different toothbrushes were selected for oscillations and pulsations type of electric toothbrush. A is Oral-B D12 (7,600 pulsations), B is Oral-B D16 (20,000 oscillations and a 7,600 pulsations), C is Oral-B D20 (40,000 oscillations and an 8,800 pulsations). In each trial, each tooth was brushed for 2 seconds. For the 10 trials. And each tooth was coated with 1layer, 2layers and 3layers. After the experiment, the plaque removal effect was calculated and analzed using the Image J program(p<0.05). According to the study, C toothbrush had the highest rate of plaque removal effect. Based on this results of the study, dental worker will need to evaluate oral hygiene and recommend appropriate toothbrushes according to oral conditions.
