If doing an intraosseous injection, practitioners should inject LA slowly in order to limit the increase in heart rate.
Intraosseous anesthesia steps:
- Take a bitewing radiograph to ensure sufficient bony space between the roots.
- Apply topical anesthetic.
- Do a preparatory infiltration so the perforation is painless.
- Do the perforation over attached gingiva. The perforation should remain perpendicular to the buccal cortex. The perforation should be done in a pecking motion for less than 5 seconds.
- Slowly inject 1/2 a cartridge of local anesthetic over 30 seconds to 1 minute.
- Use a maximum of 1 cartridge of local anesthetic per appointment.
