  1. What are the recommendations for patients with cancer with mucositis?
    • Palliative care: topical solutions such as a mixture of lidocaine, cough syrup, and a coating agent (milk of magnesia).
    • Cryotheraphy such as chewing on ice chips, and bland rinses of sodium bicarbonate or salt.
    • Systemic prednisone or narcotics such as morphine.
  2. What are things patients with mucositis should avoid?
    • Patient’s should be counseled to avoid hot, spicy, acidic, and rough-textured foods.
    • Mouth rinses containing alcohol and foods and beverages with high sugar content.
    • Chlorhexidine, sucralfate, and antimicrobial lozenges.
  3. What is grading?
    • Determining the histologic subtype.
    • It is accomplished by determining degree of differentiation exhibited by the cells and how closely the cells resemble normal tissue structure.
  4. What is staging?
    • Determining the clinical extent.
    • It’s based on the size and extent of metastatic spread of the lesion.
  5. How is the stage of cancer determined?
    • tumor-node-metastasis (TNM).
    • Three clinical features specify the stage:
    • Size of tumor (T) in centimeters.
    • Involvement of local lymph node (N).
    • Presence or absence of distant metastasis (M).
  6. How do health care providers diagnose oral cancers?
    • By performing oral cancer screenings annually on all patients. 
    • Surgical biopsy is the only definitive method
    • available to DIAGNOSE oral carcinomas. Other means have since been used to help
    • visual DETECTION of the lesions which include:
    • 1. Exfoliative Cytology
    • 2. Toluidine Blue

  7. How do we treat primary avulsed detention?
    Many recommend that primary teeth never be replaced.
  8. How should we tx permanent avulsed
    • Avulsed PERMANENT teeth should be reimplanted and proper tooth
    • preservation should be used.
  9. Discolored primary teeth is caused by?
    Damage to the permanent tooth germ.
  10. What are possible recommended treatments for primary discolored teeth?
    No treatment is recommended as these teeth will naturally exfoliate.
  11. Where should you store avulsed teeth in?
    • Hanks balanced salt solution (HBSS)

  12. Is dry media as good as wet media?
    No, air drying rapidly reduces the chance of successful reimplantation.
  13. Why is water not the best media to store avulsed teeth?
    • Water’s low osmolality results in periodontal ligament death.
    • Storage of avulsed teeth on ice is a low alternative if none of theapproved storage media are available.

  18. Which bacteria causes dental decay?
    The mutans Streptococci and lactobacilli
  19. What is cellular immunity and its components?
    • Cellular immunity is carried out by T cells from the thymus, T cells originate from cells formed in the blood marrow but these cells mature in the thymus.
    • T cells migrate from the lymph nodes, spleen, and blood.
  20. What is humoral immunity and its components?
    Humoral immunity is carried out by B cells from the bone marrow. (Tonsils contain many B-cells).
  21. What does saliva provide?
    • Lubrication
    • Flushing/rinsing

  34. What are the most common dentifrice abrasives?
    Carbonates, phosphates, and silicas.
  35. What is the difference between particle size of abrasive and polishing particles?
    Small particles (1mm) have a polishing action and larger particles (20mm) have an abrasive action.
  36. What is abrasion? What does it typically appear like on a tooth?
    Loss of dental tissue caused by hard toothbrush, an abrasive toothpaste and intensive horizontal brushing technique. Appears as v-shaped notches at cervical regions of facial tooth surfaces.
  37. What are humectants? What are common examples of humectants?

    Activity against caries, plaque, and gingivitis.
  41. What are examples of desensitizing agents? What is their mechanism?
    • Potassium nitrate.
    • It reduces the reaction of nerves in the teeth to stimuli such as heat & cold. It is known to desensitize the nerve by penetrating through the length of dentinal tubules & to depolarize sensory nerve endings located at the dentin-pulpal interface.

    • Type II: slight to moderate recession of papilla.
    • Type III. Extensive recession or complete loss of papilla.
  46. What are recommendations for hygiene of each type of embrasure?
    • Type I : Waxed dental floss or unwaxed round floss.

    • Over-the-counter 0.05% fluoride rinse is helpful in diminishing enamel loss.
    • Don't brush the teeth for at least an hour after vomiting. The enamel becomes soft due to stomach acid.
    • Using a tongue cleaner to remove acid from the papillae is crucial.
    • Limiting nonabrasive dental products for maintenance appointments is important and the use of enamel promoting dentifrices is optimal.

    • Peri-implantitis is implant failure irreversible bone loss caused by inflammation.
    • Peri-mucositis is precursor to peri-implantitis which is plaque induced reversible inflammation of surroundings soft tissues.
  53. What are implants made of?
  54. Why is it important to keep implants clean and not scratch their surface?
    • A scratch implant provides a rough surface that can trap plaque biofilm.
