There is no significant difference in the plaque removal efficiency of a manual toothbrush following the modified bass brushing method compared to an electric toothbrush. The Modified Bass method is suitable for patients with periodontitis and does not cause further gum recession or tooth loss causing sensitivity. First, the bristles are positioned correctly at an angle of forty-five degrees to the long axis of the teeth, with part of the bristles on the gums and part of the bristles on the teeth, with four to five horizontal chattering strokes of about 1mm, then brushing vertically towards the occlusal surface of the teeth. The lower front teeth can be brushed vertically against the tongue, without horizontal tremors. Pull the brush horizontally on the occlusal side of the posterior teeth. Brush your teeth for 3-5 minutes each time, twice a day. Also take care to clean the teeth and the surfaces immediately adjacent to the teeth with dental floss or a toothbrush after brushing. Daily daily cleaning is important because plaque attached to the tooth surface for 12 hours begins to cause disease, and without careful and effective brushing relying on six months of scaling alone is not enough to ensure the health of periodontal tissue.
