Patient Case SimulationsExample #1
Which teeth (write the numbers) might have significant pulpal and/or periapical pathosis and require additional testing?
What are the radiographic findings that are significant for each of these teeth?
Root length of #8 vs. #9 Length of clinical crown – incisal edges Discuss pulp testing Discuss what organisms you would expect to see histologically
What objective test(s) is (are) indicated for each tooth? Thermal, electric, percussion, palpation, probing, mobility
