Press the gingival-dental interface, so that one part of the bristles will enter the gingival sulcus, and the other part will be spread out at the gingival margin, reaching into the adjacent gap as far as possible. With a slight pressure, the bristles will vibrate horizontally for 4-5 times in a short distance in the front and back direction. When vibrating, the toothbrush only moves about 1mm and brushes 2 ~ 3 teeth at a time. When moving the toothbrush to the next set of teeth, pay attention to overlapping placement.
Basic introduction Chinese name: Pap brushing method alias: gingival sulcus cleaning method or horizontal vibration method recommended by American Dental Association: Precautions, methods and precautions for effectively removing plaque near gingival margin and in gingival sulcus: If the lingual palatine side of anterior teeth is narrow, the toothbrush can be vertical, and the bristles enter the gingival sulcus and adjacent spaces at an angle of about 45, and vibrate briefly against the long axis of teeth. The action of brushing teeth on the maxillofacial region is to press the bristles tightly on the maxillofacial region, so that the ends of the bristles go deep into the gap and vibrate in the direction of the front and rear teeth. Oral Preventive Medicine (People's Health Publishing House, 2003) 122. Methods The operation of Pap brushing was 1. Correct grip and thumb extension are better than "praise" gesture. 2. Aim the toothbrush at the junction of the teeth and gums, and brush the maxillary teeth with bristles upward, as shown in the figure (brush the upper row of teeth, brush the bristles upward, cover the gums a little, and move the toothbrush horizontally for a short distance. Brush the lower teeth with the bristles facing down and brush according to the same principle. ) 3. The bristles make an angle of 45-60 degrees with the teeth. At the same time, the bristles are gently pressed on the teeth to make the bristles slightly arc-shaped, and the side edges of the bristles are also in considerable contact with the teeth. (The toothbrush forms an angle of 45~60 degrees with the teeth, and gently presses against the teeth, so that the side of the bristles also contacts with the teeth, but the bristles cannot be bifurcated by the teeth. 4. After the toothbrush is positioned, start to move horizontally for a short distance and brush two or three teeth back and forth for about ten times. 5. Open your mouth when brushing your teeth and see the last tooth on the right side of the upper row. Then start from the right back cheek and brush to the left; Then the left occlusal surface and the left lingual side return to the right lingual side and then to the right occlusal surface. This sequential brush won't miss anything. There is a formula for the brushing sequence: start from the right and end from the right. 6. When brushing the occlusal surface, it is also two teeth, brushing back and forth. 7. The lingual side of the maxillary posterior teeth is a difficult place to brush your teeth. The bristles are still aimed at the junction of teeth and gums, and the brush handle should be close to the front teeth. When brushing the right lingual side, the brush handle will naturally face to the left. At this time, we suggest brushing the lingual side of the right posterior tooth with the left hand, which will be much more convenient. 8. In addition, brush the buccal side of the back teeth with the same hand, that is, brush the right buccal side with the right hand. Put your left hand on your left cheek. At the same time, the brush handle can spread the cheeks to facilitate the line of sight. 9. After brushing the upper teeth, brush the lower teeth with the same principle and method. 1. Essentials of bass brush 1. Brush the gingival margin of the neck (1) Hold the brush handle, place the brush head at the neck of the teeth, with the bristles at an angle of 45 with the long axis of the teeth, pointing in the direction of the root (upper teeth up, lower teeth down), and gently apply force to make the bristles partially enter the gingival sulcus and partially enter the gingival margin. (2) Take 2-3 teeth as a group and horizontally vibrate the toothbrush for 4-6 times in a short distance (about 2mm). Then turn the toothbrush to the crown and brush the lip (palate) surface. Handle with care. (3) Move the toothbrush to the next group of 2~3 teeth and reposition it, paying attention to the overlapping position of 1~2 teeth. (4) When brushing the lingual side (palatal side) of the upper teeth, put the brush head vertically on the tooth surface, so that the front bristles contact the gingival margin or enter the gingival sulcus, do lifting vibration, brush from top to bottom, and do not brush back and forth. Brush the lingual surface of the front teeth from bottom to top. 2. Brush the buccal-lingual (palatal) surface with brushing method, which is carried out between steps (2) and (3), keeping the brushing action coherent, and brushing each part of the labial-lingual (palatal) surface of the maxillary and mandibular dental arch in sequence, without omission. 3. Brush the occlusal surface with the handle, with the bristles pointing to the occlusal surface, and brush it back and forth with a little force, paying attention to the upper, lower, left and right sections. 2. Time and frequency of brushing teeth In order to ensure that each tooth surface has enough brushing time, the brushing time is not less than three minutes each time. In order to control dental plaque, maintain oral hygiene and fresh breath, brush your teeth at least once every morning and evening.
