Contributed by:

1. What factors affect perio disease? Bacterial plaque, tooth position, mouth dryness, calculus, iatrogenic
   
2. Bacterial plaque must be present for: other agents to cause perio
   
3. What must be done for the patient with un normal tooth position?

They should be taught how to remove plaque properly from those teeth, which are not in normal position.

4. Stannous fluoride 1.64% has what affect on bacteria, when looking at bacteria in microscope?

It makes the bacteria move away from the surface.

5. List 3 things used for subgingival irrigation:

Chlorhexadine, stannous fluoride, & betadine (provone Iodine).

6. Sonic has 6000 cycles / second, driven by air, 40lbs of pressure.
   
7. Ultrasonic 20,000 driven by electrical energy.
   
8. 3 mechanisms of action for the sonic/ ultrasonic:

Lavage, vibration, & acoustic streaming.

9. Lavage: flush.
   
10. Vibration: knocks calculus loose.
    
11. Acoustic streaming: destroys cell wall.
    
12. The lighter the pressure the greater the vibration.
    
13. What should be adjusted first..second?

Adjust power first then frequency.

14. High power= calculus
    
15. Low power= deplaque
