5 Matching questions

  1. Extrinsic staining
  2. Why is it important to floss after polishing
  3. What are you looking for when evaluation of polishing
  4. What are the 2 Types of stains
  5. Intrinsic staining is caused by
  1. a 1) Exposure to medication (tetracycline)

    2) Excessive fluoride ingestion

    3) Other causes during tooth development
  2. b 1) Extrinsic
    2) Intrinsic
  3. c * Occurs on the external (top) of the teeth and may be removed by scaling &/ or polishing
  4. d 1) The teeth should be glossy & reflect light from the mirror uniformly

    2) There should be no evidence of trauma to the gingival margins or any other soft tissues in the mouth
  5. e 1) To remove any abrasive agent or debris that may be lodged in the contact area

    2) A floss threader can be used to pass the floss under any fixed bridgework to gain access to the abutment teeth

5 Multiple choice questions

  1. * Soft webbed

    * Used to clean & polish the smooth surfaces of the teeth

    * Attaches to the reusable prophy angle by either a snap on or Screw on attachment
  2. 1) Natural or synthetic materials

    2) Remove stains from deep pits and fissures of the enamel surfaces

    3) can cause severe gingival lacerations and must be used with special care

    4) Brushes are not recommended for use on exposed cementum or dentine as these surfaces are soft and are easily grooved
  3. 1) Commonly called prophy angle,

    2) Attaches to the to the slow hand piece

    3) Reusable prophy angle:- must be properly cleaned and sterilised after each use

    4) Disposable angle:- is discarded after a single use
  4. * An internal discolouration - incorporated into the enamel

    * These stains cannot be removed by scaling or polishing
  5. * Fluoride is better accepted into the enamel

    * Smooth tooth surfaces are easier for the patient to keep clean (no plaque & calculus present)

    * Formation of new deposits is slowed

    * Patients appreciate the smooth feling and clean appearance

5 True/False questions

  1. What are the different textures of abrasives:-1) Coarse
    2) Medium
    3) Fine
    4) Extra fine

    * The courser the agent the more abrasive the surface
    even a fine grit agent removes small amounts of the enamel surface

    * Use the abrasive agent that will produce the least amount of abrasion to the tooth surface

          

  2. Abrasive polishing pastes* Soft webbed

    * Used to clean & polish the smooth surfaces of the teeth

    * Attaches to the reusable prophy angle by either a snap on or Screw on attachment

          

  3. What Equipment is needed for polishing1) Suction
    2) Floss (taking the grit out)
    3) Handpiece
    4) Rubber cup
    5) Polishing paste
    6) Gauze

          

  4. Describe the rubber cup polishing technique* Rotated slowly & carefully
    by a prophy angle attached to the slow handpiece

          

  5. what are the 2 methods of removing plaque & stainAir power polishing:-
    * Uses specially designed handpiece with a nozzle that delivers pressure steam of warm water and sodium carbonate

    Rubber cup polishing:-
    * Most common technique stain removal
