Summary
Electrically powered dental instruments generally do not interfere with modern cardiac pacemakers. This study found no pacemaker irregularities during in vivo testing with common dental devices, though caution is advised for older models.
Area of Science:
- Biomedical Engineering
- Cardiology
- Dental Technology
Context:
- Electrically powered devices pose potential risks to patients with cardiac pacemakers.
- Ensuring patient safety during dental procedures is paramount.
Purpose:
- To evaluate the in vivo interaction between common electrically powered dental instruments and artificial pacemaker function in humans.
- To assess potential electromagnetic interference and induction tension from dental devices.
Summary:
- Twenty-six patients with artificial pacemakers underwent testing with dental instruments (air scaler, ultrasonic curets, electric pulp tester, electrotome) at maximum intensity.
- Pacemaker function (pulse rate, EKG) was monitored before, during, and after instrument application.
- No dental device caused pacemaker function irregularity; magnetic fields were detected from some devices at a distance, and all produced induction tension.
Impact:
- The study suggests that most modern cardiac pacemakers are not affected by electrically powered dental devices.
- A residual risk may exist with older pacemaker models or malfunctioning dental equipment.
- Findings support the safe use of these dental technologies in pacemaker patients, with noted precautions.
