叩诊是评价牙髓病和根尖周病情况的一种常用方法。叩诊通常采用口镜的末端或其他器械的柄叩击可疑的牙齿。叩击过重,对急性炎症期的牙齿可引起剧痛。为了能适当地使用力量并进行精确地记录,作者研制了一种带刻度的叩诊器。叩诊器有5时长,用不锈钢制成,有一个能拔出的弹簧活塞,在一侧有一开关。活塞可预先在6个不同的刻度上调节,每个刻度间的距离相等。其中刻度“6”代表力量最大的位置,“1”代表力量最小的位置。
Percussion is a common method of evaluating endodontic disease and endodontic disease. Percussion usually use the end of the mouth mirror or other equipment handle tapping suspicious teeth. Percussion overweight, acute inflammation of the teeth can cause severe pain. In order to be able to use force properly and record accurately, the authors developed a graduated pulser. The percussion device has a duration of 5, made of stainless steel, a spring-loaded piston that can be pulled out and a switch on one side. Pistons can be pre-adjusted in 6 different scales, the distance between each scale equal. One scale “6” represents the position of the greatest strength, “1” represents the position of the least strength.
