Based on the current evidence, it is recommended that use of magnetostrictive ultrasonic equipment be avoided
on or near individuals with implantable cardiac pacemakers or cardioverter–defibrillators.6 At this time,
piezoelectric equipment appears to have no substantial effects on these devices.1,6 Further in vivo clinical
trials are warranted to determine the precise effect of ultrasonic dental equipment on
cardiovascular implantable electronic devices.
Cardiac Implanted Devices and Electronic Dental Instruments
A number of studies have shown some electronic dental devices may cause interference with implanted cardiac devices.
Newer cardiac devices are better shielded and may be less susceptible to interference.
Piezoelectric dental scalers may be safer than magnetostrictive models.
Electrosurgery devices have the highest potential of electromagnetic interference.
Proper use and distance are two important factors affecting risk of interference.
