Do ultrasonic dental scalers interfere with implantable cardioverter defibrillators? An in vivo investigation.

Objectives: To test the in vivo effects of an ultrasonic dental scaler on various implanted cardioverter defibrillator (ICD) models.

Methods: 12 consecutive patients with ICDs had continuous both electrocardiogram monitoring and device interrogation to detect interferences during the use of an ultrasonic dental scaler.

Results: No interferences were detected by any ICD.
