  1. Characteristics of tar.
    particulate matter generated from burning tobacco which appears as a sticky brown substance.
  2. Describe the characteristics of Nicotine.
    found in tobacco leaves, addictive, processed in the liver (80%) excreted in the kidneys.
  3. Characteristics of Carbon Monoxide
    competes with oxygen. Reduces O2 carrying ability. Crosses the placenta and reduces O2 to the fetus. increases the risk of cardiovacular disease.
  4. List carcinogenic compounds in tobacco
    • Nitrosamines-organic, cancer causeing.

  5. Absorption of Smoking.
    Tar & carcinogenic compounds affect the oral and resp. tissue prior to absorption, once nicotine is in the lungs it passes quickly to circulatory system.
  6. Distribution of smoking:
    once absorbed, nicotine, tar and carcinogens are processed in the liver, sent to brain, and excreted in the kidney. Once nicotine is in the liver, converts to cotinin. Once in the brain, triggers release of dopamine, noreip, endorphins, and serotonin.
  7. Absorption of spit tobacco
    directly thru mucosa. 2-3 X more absorb. into circulatory than cigarettes.  Secondary absorption is in the intestinal tract if swallowed.

    • gram - most suseptible
    • less tissue trauma
    • increased pt comfort
    • decreased operator fatigue
    • MAY req less tx time
    • Better access to deep pockets
    • no sharpening, less lateral pressure, less tissue distention
  150. lavage
    • water flushes debris
    • removes endotoxins
    • removes plaque
    • can add a antimicrobial
  151. Disadv of ultrasonics
    • decrease tactile sense
