Abstract

Eight different electrical dental appliances were tested at different intervals for their ability to interfere with the function of a contemporary cardiac pacemaker. The normal atrial and ventricular pacing was inhibited by an ultrasonic bath cleaner at a distance of less than 15 cm. In contrast, a dental chair, an electrosurgical unit, an ultrasonic tooth scaler, 2 handpieces, and 2 amalgamators failed to produce electromagnetic interference at the minimum distance of 2.5 cm. In conclusion, the results suggest that normal clinical use of dental electrical equipment does not have any significant effect on the cardiac pacemaker tested.

摘要

对八种不同的牙科电气设备在不同间隔时间进行了测试，以检测它们干扰当代心脏起搏器功能的能力。在距离小于15厘米时，超声波清洗器会抑制正常的心房和心室起搏。相比之下，牙科椅、高频电刀、超声波洁牙器、2个牙钻手机和2个汞合金搅拌机在最小距离2.5厘米时未能产生电磁干扰。总之，结果表明牙科电气设备的正常临床使用对所测试的心脏起搏器没有任何显著影响。
