5 Matching questions

  1. How would you avoid over production of saliva during polishing
  2. Intrinsic staining
  3. Patient preparation for polishing
  4. Extrinsic staining is caused by
  5. What Equipment is needed for polishing
  1. a 1) Suction
    2) Floss (taking the grit out)
    3) Handpiece
    4) Rubber cup
    5) Polishing paste
    6) Gauze
  2. b 1) Start on the upper buccal then upper palatal

    2) Then lower buccal then lingual

    * Flavours influence production of saliva
    * Use a thin layer on the teeth
  3. c 1) Check the patients medical history for any contraindications

    2) Drape the patient with waterproof bib

    3) Ask patient to remove any dental prosthetic appliance he or she may be wearing

    4) Provide the patient with protective eye wear
    explain the procedure to the patient & answer any questions
  4. d Substances such as:-
    * Tobacco
    * Coffee
    * Tea
    * Red wine
    * Certain drugs
    * Chromogenic bacteria
  5. e * An internal discolouration - incorporated into the enamel

    * These stains cannot be removed by scaling or polishing

5 Multiple choice questions

  1. * Used to remove stain & to polish natural teeth. prosthetics appliances, restorations & casting
  2. * A technique used to remove plaque & stains from the coronal surfaces of the teeth

    * A dental handpiece, a rubber cup & an abrasive agent are used
  3. 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
  4. * The more agent used the greater the degree of abrasion

    * The lighter the pressure the less abrasion

    * The slower the rotation of the cup, the less abrasion
  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. Extrinsic staining* Occurs on the external (top) of the teeth and may be removed by scaling &/ or polishing

          

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

          

  3. How would you clean dental instruments during treatment1) Start on the upper buccal then upper palatal

    2) Then lower buccal then lingual

    * Flavours influence production of saliva
    * Use a thin layer on the teeth

          

  4. What are you looking for when evaluation of polishing1) 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

    2) Intrinsic
