Periodontal Ligament Injection (Intraligamentary Injection) The periodontal ligament injection has been used for a number of years as either a method of obtaining primary anesthesia for one or two teeth or as a supplement to infiltration or block techniques.

What is Intraligamentary anesthesia?

Periodontal Ligament Injection (Intraligamentary Injection) The periodontal ligament injection has been used for a number of years as either a method of obtaining primary anesthesia for one or two teeth or as a supplement to infiltration or block techniques.

How do you use a PDL syringe?

The tip is placed at the buccal furcation of the tooth. Slide it subgingival parallel to the root surface until it contacts the bone/periodontal ligament area. Push the syringe apically with mild pressure to wedge it into the PDL space. Slowly inject half a rubber stopper amount into this area.

Where is an Intraligamentary injection placed?

The ILA starts with needle (27-30G, 0.3-0.4mm in diameter) insertion in the periodontal ligament space between the root of the tooth and the alveolar bone.

What is Citoject?

Syringes (e.g. Citoject) developed specifically for intraligamentary anaesthesia make it possible to overcome the interstitial resistance in the dense desmodontal tissue. For each root of the tooth being treated, only 0.2 ml of anaesthetic is administered very slowly (for at least 20 seconds).

How do you give a Nasopalatine nerve block?

Technique (multiple penetration)

  1. Hold the needle at right angles to the papilla.
  2. Retract the lip to improve visibility.
  3. Insert the needle into the papilla just above the crest of bone.
  4. Direct it toward the incisive papilla on the palatal side of the interdental papilla while slowly injecting anesthetic solution.

Is PDL injection painful?

Mansour and Adawy25 found that 96% of the patients claimed PDL injection was less painful than other techniques. Marin26 stated that patients reported hardly being aware of pain with PDL injection.

What is PDL injection?

The periodontal ligament (PDL) anesthetic technique involves using high injection pressure to force the local anesthetic solution through the PDL into the can- cellous medullary bone surrounding a tooth.

What is a Intraligamentary syringe?

The intraligamentary syringe (Figure 3) offers a mechanical advantage to the prac- titioner by using a trigger-grasp or click apparatus to employ a gear or lever that enhances control and results in increased force to more easily push the anesthetic cartridge’s rubber stopper forward for fluid deposition.

How do you give a PSA a nerve block?

Technique:

  1. Upward (superiorly at a 45 degree angle to the occlusal plane).
  2. Inward (medially toward the midline at a 45 degree angle to the occlusal plane).
  3. Backward (posteriorly at a 45 degree angle to the long axis of the molar) to a depth of 10-14mm.

Is pulpectomy safe?

A pulpotomy is a very safe procedure and there are no serious risks associated with it. Pulpotomies should not be performed if the pulp in the root (the radicular pulp) is not vital. That means that the pulp there should not be infected and should still be healthy at the time of the procedure.
