-
What are some characteristics and uses of the Beavertail

- ALS, muscular dystrophy, MS, Parkinsons, paralysis, following stroke
- Severe Gagging
-
What are some Precautions for Ultrasonics
Hearing Aids: May ask to turn off/can cause interference
AAP recommends that dental healthcare workers avoid exposing patients with older, unshielded cardiac pacemakers to magnetostrictive devices. (newer pacemakers are ok)
-
Ultrasonics should not be used on ________ teeth
primary and newly erupted teeth have large pulp chambers that are more susceptible to damage from the vibrations and heat produced by ultrasonic instrumentation
-
Inserts should not be placed in solutions containing ________
