Discuss technique errors that lead to failure of anesthesia of the inferior alveolar nerve
What will be an ideal response?
Technique-related errors that lead to failure of anesthesia of the inferior alveolar nerve occur when deposition is too:
1. Shallow (less than 20 to 25 mm for a typical adult)
2. Low (solution diffuses below the foramen due to gravity)
3. Medial (the sphenomandibular ligament forms a soft tissue barrier to diffusion)
4. Posterior (risks depositing into the parotid gland)
