Theory II

  1. presence of bacteria in blood
  2. lipopolysaccharide (LPS) complex found in the cell wall of many gram-negative microorganisms; contained superficially within periodontally involved cementum
  3. anatomic area between the roots of a multi-rooted tooth
  4. pathologic resorption of bone within a furcation
    furcation invasion
  5. area on tooth where instrumentation is confined; area where calculus and altered cementum are located and treatment is required
    instrumentation zone
  6. dental biofilm removal and control and subgingival scaling, root planing, and adjunctive treatments such as the use of chemotherapy; the basic objectives are to restore periodontal health; arrest or slow the progression of earyl disease, to prepare the tissues for more complex periodontal therapy
    nonsurgical periodontal therapy
  7. a definitive procedure designed to remove altered cementum or surface dentin that is rough, impregnated with calculus, or contaminated with toxins or microorganisms.
    root planing
  8. instrumentation of the crown or root surfaces to remove biofilm and calculus
  9. agitation in the fluids surrounding a rapidly vibrating ultrasonic tip; has potential to disrupt the bacterial matrix
    acoustic turbulence
  10. action created by the formation and collapse of bubbles in the water by high-frequency sound waves surrounding an ultrasonic tip
  11. type of rod with unusually high magnetic permeability used in magnetostrictive ultrasonic unit inserts
  12. a unit of energy equal to 1000 cycels per second
    kilohertz (kHz)
  13. the therapeutic washing of the pocket and root surface to remove endotoxins and loose debris
  14. space occupied by magnetic lines of force
    magnetic field
  15. ultrasonic scaling device that generates a magnetic field and produces tip vibrations by the exapansion and contraction of a metal stack or rod
  16. ultrasonic scaling device activated by dimensional changes in crystals household in the handpiece
  17. type of mechanical power-driven scaler that functions from energy delivered by a vibrating working tip in the frequency of 2500 to 7000 cycles per second; driven by compressed air, the handpiece connects directly to a conventional rotary handpiece tubing
    sonic scaler
  18. magnetostrictive inserts made of flat metal strips stacked, or sandwiched, together; metal in stack acts like an antenna to pick up magnetic field and cause vibration
  19. a device that converts energy or power from one form to another
  20. power-driven scaling instrument that operates in a frequency range between 25,000 to 50,000 cycles per second to convert a high-frequency electrical current into mechanical vibrations
