Transcript of Suplemental Technique

Suplemental Technique
Intraseptal Injection
Osseous and soft tissue anesthesia and hemostasis for periodontal curettage and flap
Intraosseous Injection
Intrapulpal Injection
Obtaining profound anesthesia in pulpally involved tooth is a problem esp for mandibular molars.
Deposition of LA directly into coronal portion of pulp chamber provides effective anesthesia for pulpal extirpation and instrumentation
STA-Intraligamentary Injection
Moderate to severe discomfort using high-pressure syringe techniques
PDL Injection
1. Infection or Inflammation at the site of injection
2. Primary teeth
+ No anesthesia of lip, tongue
+ Minimum dose of LA (0,2 mL per root)
+ Alternative to partially successful regional nerve block
+Rapid onset (30s)

- Leakage of LA solution into mouth
- Excesive presure or overly rapid injection may break cartridge (conventional syringe)
- Administration with conventional or PDL syringe is painful.
- Post injection discomfort
- Potential for extrusion if excessive pressure (too rapid injection) or volume are used
1. 27-gauge short needle
2. Insert needlein mesial or distal root or lingual or buccal surface as close to long axis as possible. Bevel toward the root
3. Advance the needle apically until resistance is met
4. Deposit 0,2 mL in a minimum 20S
5. Indicators of success: resistance to deposition of LA (noticeable with conventional syringe), LA should not flow back into mouth. Happens --> repeat from different angle.
Do not inject too rapidly (20S for 0,2 mL)
Do not inject too much solution (0,2 mL per root)
Do not inject into infected or inflamed tissues
CI: infection or severe inflammation
+ Lack of lip and tongue anesthesia
+ Minimum volume of LA
+ Useful on periontally involved teeth (avoids infected pockets)
+ Rapid onset <30s
- Bitter taste if leakage
1. 27G
2. Insert in the center of interdental papilla adjacent to the tooth to be treated. 2mm below interdental. bevel toward apex
3. Right angle to the soft tissue and 45 degrees to the long axis of the tooth
4. Slowly inject a few drops of LA as needle enters soft tisse and advance until contact with the bone
5. Push the needle slighly deeper (1-2mm) into interdental septum
6. Deposit 0,2 mL not less than 20S
7. Indication of success: Significant resistance, solution not come back into mounth (occurs --> repeat with needle slighlt deeper), ischemia of soft tissue
Do not inject too rapidly (20S for 0,2 mL)
Do not inject too much solution (0,2 mL to 0,4 mL per site)
Do not inject into infected or inflamed tissues
Intrapulpal injection provide pain control through pharmacologic LA and applied pressured
CI: none
-Intrapulpal injection has a brief period of pain as anesthetic is deposited
1. 25 or 27 G short or long needle into pulp chamber
2. Wedge the needle firmly. If does not snug, deposit in the chamber. Anesthesia in this case is produced only by pharmacologic action of LA. no pressure anesthesia
3. Deposit 0,2-0,3 mL
When intrapulpal injection is performed properlu, a brief period of sensitivity is felt
STA System precisely regulated flow rate and controlled low pressure injection to perform PDL. STA provides continuous audible and isual feedback to the clinician as the dental needle is introduced into the tissue duting injection.
Orange : minimal pressure
Yellow: mild to moderate
Green: moderate
Auditory: ascending tone --> pressure is rising.
When PDL is identified, "P-D-L'
Transforms blind syringe approach into an objective method
1. Place slowly into gingival sulcs as if it is a probe, simultaneously intiacting ControlFlo (press foot control --> 3 beeps --> "CRUISE"
2. Advance the needle until resistance
3. Minimize movement as DPS is analyzes. Illumination and ascending tones
4. 20-30 s "P-D-L" and 2 longer beeps
