Rdh Clinical Review Quiz - Quiz

This quiz assesses dental hygiene students' readiness to work with patients in a clinical setting.


Questions and Answers
  • 1. 

    Your clinical patient, Mary Doe, arrives for her semi-yearly dental appointment for a "cleaning and dental examination."  While assessing her soft tissues and periodontium, you note the presence of gingival swelling and redness in the maxillary posterior regions.  You also note bleeding upon probing and periodontal pockets around the following teeth:  #2 - 5mm MB, #3 - 4mm DB, #14 - 6mm DB, #15 - 5mm MB, and #15 - 5mm MLi.  You also detect a malodor.  Your patient has been unaware of the breath odor; however, she does report bleeding upon tooth brushing.  These findings are indicative of:

    • A.

      Gingivitis

    • B.

      Oral Cancer

    • C.

      Medication Side Effect

    • D.

      Periodontitis

    • E.

      Osteoporosis

    Correct Answer
    D. Periodontitis
    Explanation
    Periodontitis is the correct answer. Although the signs of infection (swelling, redness, and bleeding) could simply indicate Gingivitis, the significant loss of interproximal bone surrounding those maxillary posterior teeth denotes periodontal disease. Moreover, periodontitis is often demarked by a malodor. Osteoporosis can play a role in periodontal bone loss; however it is not the described condition. Similarly, certain medication side effects can contribute to periodontal infections, but are not the condition. Oral Cancer does not resemble periodontitis.

    On your patient's (Mary Doe) full-mouth set of radiographs, you notice a triangular-shaped opacity in the interproximal space between teeth #14 and #15.  What is this radiographic opacity?

    • A.

      Patient's tongue

    • B.

      Calculus

    • C.

      Supernumerary Tooth

    • D.

      Abscess

    • E.

      Food Debris

    Correct Answer
    B. Calculus
    Explanation
    Calculus is the correct answer. Calculus is over 70% calcified. Its density absorbs some of the X-radiation causing film crystals to be underexposed, thus creating an opaque image on a radiograph. In addition, calculus usually forms deposits which cling to the cervical area of the tooth and are typcially seen as triangular shapes in the interproximal spaces on radiographs. The patient's tongue is soft tissue which lacks calcification and density, so it can not be detected on a FMX. Supernumerary teeth are calcified and are seen as opaque on an x-ray; however, they are shaped like teeth and typically have a root attachment. Food debris is not dense enough to be seen on an x-ray.

    If a patient in the dental office is a regular client and comes in semi-annually for check-ups, it is not necessary to review his/her medical history at each dental appointment.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The overall health of the patient and the success of the dental procedure can be impacted by various health conditions, immune responses, and medications. It is vital to the patient's health and/or success of the dental procedure that a medical update is ascertained prior to each dental appointment to determine whether the procedure is contraindicated.

    Rate this question:

  • 4. 

    It is appropriate for the dental hygienist to review a patient's dietary habits and explain the impact such habits have on the patient's oral health.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Nutrition and dietary habits have a direct effect upon the health of the teeth and oral tissues. It is within the scope of the dental hygienist to evaluate and counsel patients about their dietary intake and habits.

  • 5.
