On which type of tissues does topical anesthesia work well?
Non-keratinized tissues
Which of the following topical anesthetics has a higher concentration?
Benzocaine
What is the reason for preferring regional blocks over infiltration in the mandible?
The thick cortical plate prevents diffusion of solution to apical nerves
What action should be taken if bony contact is made during infiltration anesthesia?
The needle should be withdrawn and the solution deposited
What is the purpose of stretching the tissue for penetration of the needle during infiltration anesthesia?
To make the injection comfortable for the patient
What is the recommended amount of solution to inject according to 'Malamed'?
0.6ml
What benefits are associated with injecting 1.2ml solution?
Faster onset, longer duration, greater success
When does the effect of 'pulpal' anesthesia start to decline?
35-45 minutes
What is the advantage of infiltration anesthesia?
It prevents numbness in a wide area
What action should be taken if bleeding occurs at the site of injection during infiltration anesthesia?
Apply pressure for 2 minutes
Which tissues are anesthetized during infiltration anesthesia?
Buccal bone, gingiva, Buccal periodontium, cheek mucosa adjacent to injection
Why are slow injections more comfortable for the patient?
The tissue space in which solution is injected expands slowly
What is a benefit of detecting adverse reactions during slow injections?
Adverse reactions can be detected before the entire solution is deposited
Why is the solution more likely to remain at the intended site with slow injections?
The tissue space in which solution is injected expands slowly
Why is palatal infiltration generally associated with more pain and discomfort?
Due to the tightly adherent palatal mucosa
What is the recommended amount of anesthetic solution to be deposited during palatal infiltration?
0.2ml
What technique can be used to make palatal infiltration more comfortable for the patient?
Pressure anesthesia
Where is the Greater palatine nerve block foramen located?
Distal to the second molar
During an infraorbital nerve block, which teeth are anesthetized?
Maxillary lateral incisors, canines, and first premolars
Why may the maxillary central incisors not be fully anesthetized during an infraorbital nerve block?
Due to cross innervation from the other side
Why may an infraorbital nerve block not work well for second premolars?
Due to middle superior alveolar nerve supplying the second premolar
What is the length of the short needle typically used for the posterior superior alveolar nerve block?
20-25mm
At what angle is the needle advanced during the posterior superior alveolar nerve block?
45 degrees superiorly, posteriorly, and medially
Which pulp/root is not anesthetized by the posterior superior alveolar nerve block?
Mesiobuccal pulp/root of 1st molar
What complication may arise if the needle penetrates the pterygoid plexus of veins during a posterior superior alveolar nerve block?
Hematoma formation
What is a potential consequence of nicking the maxillary artery during a posterior superior alveolar nerve block?
Bleeding
What should be done if a hematoma occurs during a posterior superior alveolar nerve block?
Apply pressure in the pterygoid region for 5 minutes
Which structures are anesthetized by a maxillary nerve block?
Pulp of the maxillary teeth, buccal periodontium, hard palate, lower eyelid skin
What is the main purpose of a maxillary nerve block?
To provide anesthesia for extensive maxillary procedures
What is another common name for the maxillary nerve block?
Second division block
