Myth or Fact: Dentistry Damages Devices?

● Pacemakers and other programmable devices are susceptible to electromagnetic radiation

● Unipolar devices are less susceptible but still can be affected

● Shielding and refinements in cellphones and devices reducing risk

Myth or Fact: Dentistry Damages Devices and Data?

• Miller CS et al. Selective interference with pacemaker activity by electrical dental devices. OOOOE 1998;85:33-6

● Regardless of polarity, pacemakers were affected by electrosurgery, ultrasonic scaler and ultrasonic cleaner

● Handpieces, amalgamator, curing light, pulp tester, x-ray unit, and sonic scaler were all benign

● Electric toothbrushes ok

Anything Else?● Anecdote: My cardiology colleagues say that in

some patients with CHD, the reduced IE coverage is prompting delay in repair

● Low-dose anti-neoplastics are growing in popularity (multiple sclerosis and cyclophosphamide)

● Implanted “pacers” are increasing in use (gastroparesis)

● Do not assume that historical disease-treatment patterns hold in today’s pediatric medicine!

Sign of caries risk

● 12 month old infant● Initial Examination● Plaque on anterior teeth● Is there a risk for ECC?

● EB Decision ‘Reviews suggest that

visible plaque on the labial surfaces of infants maxillary incisors is a sign of caries risk’

teeth. If not removed regularly, it can lead to dental cavities or periodontal problems (such as gingivitis).

Periodicity of Radiographs

● Ordering of radiographs only after a review of histories, completing a dental examination and a risk assessment.

● Order only if the child’s cooperation is acceptable

● Order only if there is an expectation that the information will affect patient care

● Minimize patient’s exposure ● Ionizing radiation can result in high

cumulative effective doses of radiation
