Study Notes
Dental Anesthesia Techniques
- Intraosseous, intraseptal, and PDL injections are recommended for accessing the pulp chamber of mandibular teeth.
- Intraosseous injection has gained renewed interest and can provide profound anesthesia for painless access to the pulp chamber.
- The intraosseous technique involves topical anesthetic application, perforator insertion, and local anesthetic deposition.
- Intraseptal injection, a variation of intraosseous and PDL injections, is more successful in younger patients due to decreased bone density.
- PDL injection is effective for pulpally involved teeth without infection or severe inflammation.
- Intrapulpal injection is indicated when supplemental injections fail to provide anesthesia for mandibular posterior teeth with irreversible pulpitis.
- Intrapulpal injection provides pain control through pharmacologic action and applied pressure once the pulp chamber is exposed.
- In cases where other techniques fail, a sequence of treatment involving slow-speed high-torque instrumentation, sedation, and direct intrapulpal anesthesia may be effective.
- If high pain level persists, placing a cotton pellet saturated with local anesthetic on the pulpal floor and subsequent removal can provide insensitivity for pulpal access.
- Difficulty in providing adequate anesthesia in endodontic procedures typically occurs only at the initial appointment.
- Once pulp tissue is removed, the need for pulpal anesthesia diminishes, although soft tissue anesthesia may be necessary for ensuing appointments.
- Computer-controlled local anesthetic delivery devices enable more successful and comfortable PDL injections.
