MCQs in Endodontics

Chapter 23: Geriatric endodontics


 1- Periapical radiographs should be reviewed:

  1. before discussion of the chief complaint.
  2. after discussing the chief complaint with the patient.
  3. just before the clinical examination.
  4. after completing the clinical examination.







The answer is: D


 2- With aging:

  1. lateral canals become more clinically significant.
  2. gingival recession exposes cementum and dentin, which is less resistant to decay.
  3. the cementodentinal junction moves closer to the radiographic apex with continuous apical remodeling.
  4. All of the above.







The answer is: B


3- Which pulp tests have limited diagnostic value in geriatric patients:

  1. Electric pulp tests.
  2. Test cavity.
  3. Selective anesthesia.
  4. All of the above.







 The answer is: D


 4- Cracked teeth:

  1. are rare in geriatric patients.
  2. will not have pulpal or periodontal disease unless the cause of pulpal irritation is evident
  3. with periapical disease and normal pocket depths have an excellent prognosis following root canal therapy.
  4. when associated with periodontal pockets have a poor prognosis.







The answer is: D


 5- In geriatric patients:

  1. there is a direct correlation between the degree of response to electric pulp testing and the degree of inflammation.
  2. there is a reduced volume and increased neural component of the pulp.
  3. tooth discoloration usually is not indicative of pulpal death.
  4. diffuse pain of vague origin is common.







The answer is: C


 6- In the geriatric patient, with increasing age, radiographically:

  1. the incidence of condensing osteitis increases.
  2. the incidence of odontogenic and nonodontogenic cysts increases.
  3. the apical constriction is closer to the radiographic apex.
  4. All of the above.







The answer is: B


 7- Regarding endodontic treatment in aged patients:

  1. one appointment procedures are advantageous.
  2. frequent appointments of short duration are preferable.
  3. root canal treatment is more traumatic than extraction.
  4. intraligamentary injection is the recommended technique for obtaining anesthesia.







The answer is: A


 8- The frequency and intensity of discomfort following instrumentation is not related to:

  1. the amount of preparation.
  2. pulp or periapical status.
  3. whether or not the root canal is tilled at the same appointment.
  4. All of the above.







The answer is: D


 9- In evaluating success and failure of endodontic therapy in aged patients, one must consider that:

  1. the bone of the aged patient is more mineralized than that of a younger patient.
  2. overlooked canals are seldom a problem because they are usually calcified.
  3. as long as 2 years may be necessary to produce healing that would occur at 6 months in an adolescent.
  4. cold sensitivity is the only symptom that may indicate a missed canal.







The answer is: C


  10- Endodontic surgery in geriatric patients:

  1. requires more anesthetic and vasoconstrictor than in younger patients.
  2. is usually indicated to establish drainage or for relief of pain.
  3. produces postoperative eechymosis more commonly than in younger patients.
  4. seldom requires the placement of a retrograde filling.







The answer is: C
