Which of the following factors most commonly leads to the failure of an inferior alveolar nerve block? A) Inadequate patient cooperation during injection B) High concentration of vasoconstrictors C) Using a needle that is too short D) Inappropriate volume of anesthetic used
Understand the Problem
The question is asking for the factor that most commonly contributes to the failure of an inferior alveolar nerve block, which is a specific technique used in dentistry to numb an area in the lower jaw.
Answer
Poor technique is the most common reason for failure.
Poor technique is most commonly the reason for the failure of an inferior alveolar nerve block.
Answer for screen readers
Poor technique is most commonly the reason for the failure of an inferior alveolar nerve block.
More Information
The most common cause of failure in inferior alveolar nerve blocks is attributed to poor technique, indicating the importance of accurate anatomical knowledge and precise administration techniques.
Tips
A common mistake is assuming that inadequate patient cooperation or the concentration of vasoconstrictors are significant factors in most failures, but technique is usually the main issue.
