ABGD Study Guide Resource - All Answers Confirmed Correct

ABGD Study Guide Resource - All Answers Confirmed Correct The protocol for dental trauma involves all of the following, except a. Ideally, the tooth should be repositioned to its original position. b. EPT and thermal testing are unreliable following trauma since physical trauma can severe or damage nerve supply without altering pulpal blood supply/vitality. c. If the root is completely formed on a tooth that has been intruded, a pulpectomy should be performed within 1-3 weeks after the injury. d. The tooth should be splinted for 2 to 4 months if it sustains a root fracture - answer - d. The tooth should be splinted for 2 to 4 months if it sustains a root fracture When evaluating horizontal root fractures, one should consider all as being true, except: A. Chances of coronal root fractures healing are similar to mid-root or apical fractures if the fracture is below the height of crestal bone and properly splinted B. If the fracture is at or coronal to the crest of the alveolar bone, the prognosis is still favorable C. Pulpal necrosis occurs in 25% of root fractures D. In the vast majority of cases, necrosis occurs in the coronal segment only with the apical segment remaining vital - answer - B. If the fracture is at or coronal to the crest of the alveolar bone, the prognosis is still favorable How long should horizontal root fractures be splinted if the coronal section was displaced and repositioned? A. not indicated B. 7 to 10 days C. 4 to 6 weeks D. 3 months - answer - C. 4 to 6 weeks Which of the following techniques is the best way to detect a vertical root fractures? A. Periapical Film B. Panograph C. CAT Scan D. Occlusal Film - answer - C. CAT Scan Patient presents for emergency dental exam after falling off his bike and face planted into sidewalk. Upon examination, you suspect that he may have a root fracture of #8. How many angled PA radiographs would you take, at a minimum? A. Two angled films at 45 and 90 degrees to the possible fracture line B. Only one film from the distal or mesial at 45 degree to uphold ALARA, C. Three angled films at 45, 90 and 110 degrees to ensure at least one passes through the possible fracture line D. Two angle films at any angle as long as it is parallel to the long axis of the root and will reveal the fracture line. - answer - C. Three angled films at 45, 90 and 110 degrees to ensure at least one passes through the possible fracture line Assessment of a completed NSRCT is based primarily on what? A. Radiographic examination B. Pain level of the patient C. Mobility of the tooth D. EPT results E. The alignment of the planets - answer - A. Radiographic examination Research has demonstrated that the average distance from the foramen to the minor constriction is: a. 0.5 -1.0mm b. 0.2-0.4mm c. 1.0-2.0mm d. 2.0-3.0mm - answer - a. 0.5 -1.0mm Which of the following diagnostic tests is (are) not an indication of pulp vitality? 1. Percussion 2. Mobility 3. Thermal (hot and cold) A. 1 only B. 3 only C. 1 and 2 D. 2 and 3 E. all of the above - answer - C. 1 and 2 Which of following is false with respect to the use of electric pulp testing in endodontics? A. The technology is not accurate enough at this time to be utilized on a routine basis in a clinical setting. B. The response of the pulp to electric testing reflects the histologic health or disease status of the pulp. C. A response by the pulp to the electric current only denotes that some viable nerve fibers are present in the pulp and are capable of responding. D. Electric pulp test results are most accurate when no response is obtained to any amount of current (i.e. necrotic pulp). - answer - B. The response of the pulp to electric testing reflects the histologic health or disease status of the pulp. To date, the most accurate pulp test that are used to determine if a tooth's pulp is healthy is/are a. Cold b. Heat c. EPT d. Both a and b e. Both a and c - answer - e. Both a and c When applying the tube shift technique, buccal
