The Bartholomew Brushing Method The Bartholomew brushing method is also known as the gingival sulcus clearing method or the horizontal trephination method. It is recommended by the American Dental Association as an effective way to remove plaque near the gingival margin and in the gingival sulcus. First, precautions Choose a soft-bristled toothbrush, the toothbrush and the long axis of the teeth at an angle of 45 ° pointing in the direction of the root tip (maxillary teeth upward, mandibular teeth downward), according to the gingiva – tooth junction area, so that a part of the bristles into the gingival sulcus, a part of the gingival margin on the spread, and as far as possible to reach the neighboring interstitial space, with gentle pressure, so that the brush bristles in the same position in the anterior and posterior direction of the short distance of the horizontal tremor for 10 times. The toothbrush moved only about 1 mm during the trembling, and 2 to 3 teeth were brushed at a time. When moving the toothbrush to the next set of teeth, pay attention to overlapping placement. The lingual-palatal side of the anterior teeth can be placed vertically if the arch is narrow, pressing the bristles into the gingival sulcus and the adjacent space at an angle of about 45°, and making a short trembling motion against the long axis of the teeth. Maxillofacial brushing action is to press the bristles tightly on the maxillofacial, so that the bristles deep into the point gap, for the front and back of the teeth for the direction of the trembling. Second, Ba-style brushing method operation 1, the correct grip, the thumb forward than the “zan” gesture. 2, the toothbrush against the teeth and gums of the intersection of the place, brush the upper jaw teeth when the bristles face up (brush the upper row of teeth when the bristles face up, covering a bit of the gums, the toothbrush for the horizontal short distance movement.) (Brush the lower row of teeth with bristles facing downward, following the same principle.) 3, the bristles and teeth at an angle of 45-60 degrees, at the same time, the brush bristles to the teeth light pressure, so that the brush bristles slightly arc, the side of the brush bristles and teeth have considerable contact. (The toothbrush is at a 45-60 degree angle to the teeth, and lightly press the bristles toward the teeth so that the side of the bristles are also in contact with the teeth, but the bristles must not be bifurcated by the teeth.) 4, toothbrush positioning, began to make short horizontal movement, two, three teeth back and forth about ten times. 5. Open your mouth wide when brushing and see the last tooth on the right side of the upper row. Then start from the back of the right side of the cheek, brush to the left; then the left occlusal surface, the left lingual side and then back to the right lingual side, and then the right occlusal surface. If you brush in this order, you will not miss anything. (There is a mnemonic for the order of brushing: start on the right side and finish on the right side.) 6. When brushing the occlusal surface, brush two teeth at a time, back and forth. 7, the tongue side of the back teeth of the upper jaw is not easy to brush the place, the bristles are still aligned with the teeth and gums of the junction, the brush handle should be close to the incisors. When brushing the right side of the tongue, the brush handle will naturally face to the left, at this time we recommend using the left hand to brush the right side of the tongue of the back teeth, it will be much smoother. 8, in addition, brush the buccal side of the back teeth with the same side of the hand, that is, brush the right buccal side with the right hand. Brush the left cheek with your left hand. At the same time, the brush handle can spread the cheeks to facilitate the line of sight. 9, after brushing the upper teeth, and then use the same principles and methods, brush the lower teeth. In order to let you better understand, dental treasure especially find a set of moving pictures to you. Special tips, because everyone’s brushing habits are different, so the order of the tooth treasure is only a human order, not the order of authority. Third, time and frequency In order to ensure that each tooth surface has enough time to brush, each brush time is not less than one minute. In order to control plaque and maintain oral hygiene and fresh breath, brush your teeth at least once a day in the morning and evening.
