  1. What are 6 components of periodontal debridement?
    • removal of biofilm, endotoxins, bacterial products, and calc
    • root planing to remove residual calc and create a smooth surface
    • irrigation
    • sustained-release antibiotic, or antimicrobial agent particularly for refractory infections
    • removal of iatrogenic retainers
    • concurrent dental therapeutic interventions
  2. What is the focus of periodontal debridement treatement?
    focus is on the elimination of the contributing factors of the infection; dental biofilm, endotoxins, cementum, and calc
  3. What is derived from the cell walls of gram-negative pathogenic microorganisms, are toxic to human tissue, and lead to inflammation and destruction of the periodontal attachment; they are embedded in the cemental surface and in the superficial biofilm and can be removed readily
  4. true or false. In periodontal case types II, III, or IV, you should never promise that the treatment will be finished in a given number of appointments
  5. What are 4 important things to educate the pt about when treatment involves nonsurgical periodontal instrumentation?
    • appreciate values of a healthy mouth
    • assume a co-therapist role in maintaning the health established in treatment phase
    • commint to perform daily personal biofilm control
    • continue with perio maintenance appointments at recommended interavals
  6. What are 4 things to expect in the outcomes of nonsurgical therapy?
    • interrupt or stop progress of disease
    • create an environment that encourages the tissue to heal and the inflammation to be resolved
    • induce positive changes in the quality and quantity of the subgingival bacterial flora
    • provide initial preparation for complicated periodontal therapy required for advanced disease
  7. What are 5 pieces of information to include in the written instructions for the pt to take home with them after nonsurgical periodontal instrumentation?
    • possible discomfort to expect
    • rinsing - warm solution - hypertonic slat; sodium bicarbonate - rinse w/previous 2 every 2 hrs after eating and tooth brushing, and before bed; or rinse with chlorhexidine
    • toothbrushing - use soft brush
    • eating - avoid solid food until anesthetic has worn off; if tissues are tender eat bland food
  8. What are 3 predisposing factors for abscess formation?
    • deep suppurating pockets; advanced perio infection
    • pockets extending into furcation areas or intrabony defects
    • pt susceptible to infection i.e. diabetes, immunodeficiency disease, or immunosuprressants
  9. What are 5 steps leading to the development of an abscess with partial scaling?
    • healing can begin
    • the tissue at the gingival margin tightens
    • the pocket closes
    • microorganisms multiply within
    • an abscess develops
  10. _________ is the formation of tiny bubbles in the fluid; when these tiny bubbles collapse, they produce shock waves that destroy bacteria by tearing the bacterial cell walls
  11. ______ is the swirling effect produced within the confined space of a periodontal pocket by the continuous stream of fluid flowing over the vibrating instrument tip. This intense swirling effect disrupts the plaque biofilm
