Greater Palatine Nerve Block Demonstration and Overview (4K)

Summary

This video provides a detailed walkthrough of the Greater Palatine Block Injection, used to anesthetize the palatal gingiva of maxillary premolars and molars. It is ideal for procedures like crowns, fillings, extractions, and scaling. The injection site is located at the Greater Palatine foramen, two millimeters anterior to the junction of the hard and soft palate. Key techniques include using a 30-gauge short needle, applying pressure for comfort, and depositing 0.6 milliliters of anesthesia. The guide emphasizes patient comfort and precise techniques to ensure effective anesthesia.

Takeaways

• 😀 The greater Palatine block injection anesthetizes the palatal gingiva of the maxillary premolars and molars.
• 😀 This injection is useful for maxillary posterior teeth procedures like crowns, fillings, extractions, and scaling/root planing.
• 😀 The injection site is located at the greater Palatine foramen of the posterior hard palate.
• 😀 Clinically, the foramen is located 2 millimeters anterior to the junction of the hard and soft palate.
• 😀 The tissue at the injection site is soft and compressible.
• 😀 A blue 30-gauge short needle is recommended for the greater Palatine block injection.
• 😀 The insertion depth should be 2-3 millimeters due to the thin and closely attached palatal soft tissue.
• 😀 Prior to administering anesthesia, applying pressure with the end of a mirror at the injection site for one minute can help increase patient comfort.
• 😀 For adult patients, deposit 0.6 milliliters (about one-third of a cartridge) of anesthetic.
• 😀 Blanching of tissue is expected after the injection.
• 😀 This injection technique is beneficial for ensuring effective anesthesia during dental procedures in the maxillary posterior region.

Q & A

What is the purpose of the greater Palatine block injection?

The greater Palatine block injection is used to anesthetize the palatal gingiva of the maxillary premolars and molars, making it useful for procedures such as crowns, fillings, extractions, or scaling and root planing on the maxillary posterior teeth.

Where is the injection site for the greater Palatine block located?

The injection site is located at the greater Palatine foramen of the posterior hard palate, which is found two millimeters anterior to the junction of the hard and soft palate.

What is the recommended needle for administering the greater Palatine block?

A blue 30 gauge short needle is recommended for the greater Palatine block injection.

How deep should the needle be inserted for the greater Palatine block?

The insertion depth for the needle should be 2 to 3 millimeters, as the palatal soft tissue is thin and closely attached to the underlying bone.

Why is it important to apply pressure with a mirror before the injection?

Applying pressure with the end of a mirror at the injection site for one minute before administering anesthesia helps increase patient comfort during the procedure.

How much anesthetic should be deposited for an adult patient?

For an adult patient, 0.6 milliliters, or about one-third of a cartridge, should be deposited during the greater Palatine block injection.

What is expected to happen to the tissue after the injection?

Blanching of the tissue is expected after the injection, as a result of the anesthetic's effect on the blood vessels.

What types of dental procedures is the greater Palatine block injection useful for?

The greater Palatine block injection is useful for maxillary posterior teeth procedures such as crowns, fillings, extractions, or scaling and root planing.

What is the significance of the soft tissue being thin and closely attached to the bone in this injection?

The thin and closely attached soft tissue in the palatal area requires a shallow needle insertion (2 to 3 millimeters) to avoid damaging the underlying bone while ensuring effective anesthesia.

How is the injection administered to ensure maximum comfort for the patient?

In addition to using a short needle, applying pressure with a mirror before administering the anesthetic helps improve patient comfort by numbing the area and reducing discomfort from the injection itself.
