Question

Quizplus · Accepted Answer

Paresthesia can be caused by trauma to the nerve sheath during injection, pressure on the nerve from hemorrhage in the area, and injecting contaminated solution. However, it is unlikely for paresthesia to be caused by too much anesthetic solution, as it would result in numbness or paralysis rather than tingling or numbness. Therefore, choices 1, 2, and 4 are the most likely causes of paresthesia in dental anesthesia.
