H. Hiller et al., THE SAFETY EF DENTAL MINI-MAGNETS IN PATIENTS WITH PERMANENT CARDIAC-PACEMAKERS, The Journal of prosthetic dentistry, 74(4), 1995, pp. 420-421
To evaluate the safety of prosthetic mini-magnets, 12 patients treated
with implanted cardiac pacemakers were examined. Small cylindric magn
ets were applied one, two, and three at a time to constant points on t
he pacemaker under electrocardiographic monitoring. No influence on th
e pacemaker was detected in nine of the patients, but limited changes
were encountered in three patients. However, the changes disappeared w
hen the magnets were moved 1 cm away. The conclusion was that the use
of mini-magnets in dental care in patients with implanted pacemakers i
s safe and acceptable.
