Q

2 Subtypes of ultrasonics and how they differ

A
  • Piezoelectric Electrical energy activates ceramic crystals within the handpiece to make the tip vibrate
  • Magnetostrictive Electronic energy is transferred to metal stacks or to a ferrous rod.

Q

Cavitation, fluid lavage, amplitude, frequency

A

Cavitation- Tiny bubbles formed by water stream. Bubbles collapse, which produces
shock waves that may alter or destroy bacterial
cell walls.

Levage: flush
out bacteria from beneath the gingival
margin

Amplitude- How far the instrument tip moves back and forth during one cycle. (length of stroke)

Frequency- How many times the tip vibrates per second (kHz)

Q

Slim vs standard working ends- when and where they are used- appropriate power settings for each

A

Slim : Light to moderate calculus
Improved for subgingival access due to 30% thinner

Standard: Moderate to heavy calculus

Q

Contraindications to ultrasonics

A
  • Communicable diseases- Aerosol production allows for dissemination of bacterial and viral infections; Hepatitis, TB, respiratory infections.
  • High susceptibility to infection- Immunosuppressed patient due to disease or chemotherapy, uncontrolled diabetics, patients with organ transplants or chronic, debilitating medical conditions.
  • Respiratory risk- Emphysema, cystic fibrosis, asthma, cardiac disease with secondary pulmonary disease, pneumonia, breathing problems.
  • Unshielded cardiac pacemaker- Piezoelectric ok- only concern with magnetostrictive; may need physician consult to verify type of pacemaker present.
  • Dysphagia (difficulty swallowing) or prone to gagging- MS; ALS; Muscular dystrophy, paralysis
  • Age- Primary teeth and newly erupted teeth have large pulp chambers- more susceptible to damage from vibrations and heat.

Oral conditions- hypersensitive teeth; demineralized enamel surfaces, exposed dentin

-Restorations- Veneers, cast crowns, composite restorations- avoid these localized areas; place ultrasonic tip adjacent or apical to restoration- use dental chart and radiographs for guidance.
