5. Repeatability - Moved to header area.
 
6. Methods of Evaluation -
  1. Written examination: student must achieve a grade of 80% or better on a written exam that reflects the objectives.
  2. Clinical proficiency, criteria:
    1. 100% of the time the student will review the medical/dental history, general assessment and oral inspection prior to treatment at each appointment (or ascertain that this has been accomplished) checking for information which contra indicates the procedure, requires alteration in the treatment plan of further investigation and/or treatment. This information will be noted either in writing or verbally and will be acted upon appropriately (e.g., dentist consulted, treatment altered, etc.).
    2. 100% of the time the student will assemble the armamentarium required for this procedure.
      1. Topical anesthetic indicated by operator.
      2. Local anesthetic indicated by operator.
      3. Correct needle length and gauge for procedure and according to operator's preference.
      4. Aspirating syringe.
      5. Disposable supplies (e.g., gauze, 2 x 2's, etc.).
      6. Mirror.
    3. 100% of the time the student will use sterile/aseptic technique according to the following criteria:
      1. Use proper handwashing technique prior to and during each appointment at the appropriate times.
      2. Protect self from cross-infection by wearing gloves and face mask.
      3. Protect patient from cross-infection by wearing gloves and face mask
      4. Use only sterile disinfected or sanitized armamentarium and equipment
      5. Recognize and correct accidental breaks in aseptic chain to restore asepsis promptly for each occurrence.
    4. 100% of the time the student will seat and position the patient comfortably, place protective drapes, remove and safely store such items as dentures, glasses, etc., explain the procedure and provide psychological support as needed.
    5. 100% of the time the student will maintain the operating field by positioning the light for maximum illumination isolating the injection site when required and removing leaded anesthetic solution and other debris routinely to provide adequate vision and patient comfort.
    6. 100% of the time the student will administer local anesthetic as indicated below:
      1. Based on the patient's pre-anesthetic evaluation and treatment plan, identify potential emergency situations, select an appropriate anesthetic solution, identify the maximum safe dosage, determine injection(s) needed and select an appropriate needle, all with consultation of the dentist as needed.
      2. Visually and by palpation, locate landmarks to determine site and pathway of injection.
      3. Prepare site of injection for cleanliness and comfort by wiping with gauze-wipe and applying topical anesthetic (and pressure anesthetic where useful).
      4. The needle will be within 1-2 mm of the target site.
      5. Aspirate at depth of injection prior to depositing solution or prior to injecting if needle has been repositioned.
      6. Whenever necessary, adapt and modify technique to each patient's anatomical structures to ensure likelihood of achieving anesthesia and minimizing physical trauma. If there is any doubt in the operator's mind about the injection, assistance will be obtained before continuing.
      7. Make maximum observable efforts to minimize patient anxiety and discomfort by implementing one or all of the following:
        1. Position patient comfortably.
        2. Explain procedure and answer questions in such a way as to ensure patient cooperation.
        3. Calmly reassure patient throughout procedure.
        4. Avoid negative verbal stimuli (e.g., hurt, pain, shot, etc.).
        5. Inject slowly (approximately 1 cc /45-60 seconds).
        6. Avoid undue tissue trauma by not relocating needle unnecessarily through tissue.
        7. Avoid unnecessary insertions of needle (maximum insertion of three).
        8. Keep needle out of patient's field of vision.
    7. 100% of the time the student will make the necessary precautions (e.g., stay with patient following injection to observe for reaction, be alert to sudden movements, etc.).
    8. 100% of the time the student will evaluate the procedure and final product to determine that they meet criteria:
      1. In nine out of ten injections, acceptable anesthesia will be achieved on the first insertion.
      2. In all injections the amount of anesthetic will cover the procedure to be performed.
      3. All principles of acceptable technique have been observed; ways to improve (e.g., when anesthesia is not achieved, will be able to re-evaluate technique and change appropriately; if patient is anxious will be able to suggest ways to improve patient comfort and reduce anxiety, etc.,) are suggested
    9. 100% of the time the student will explain the procedure and provide pertinent, individualized education to the patient.
    10. 100% of the time the student will meet ethical and legal requirement for this procedure.
    11. 100% of the time the student will make complete, accurate chart entries for this procedure (e.g., type of injection, name, strength and amount of anesthetic solution, any unusual reaction experienced, etc.).
    12. 100% of the time the student will clean up treatment area and armamentarium.
