Traditional Periodontal Ligament (PDL) Injection Technique
The Periodontal Ligament Injection has long been advocated as a rapid, site
specific technique to anesthetize a specific tooth and the adjacent periodontal
tissue. Some of the literature suggests that due to the pressure required to
administer this injection in the traditional method with a conventional syringe or
other mechanical device, it may be contraindicated in primary teeth and teeth
with active periodontal infection or suppuration. The traditional PDL technique,
utilizing 4 injection sites with approximately 0.3 ml of anesthetic delivered at each
site, can be administered with the STA System. However, due to the STA
System’s innovative DPS™ technology, a modified technique has been
advocated to increase success with the PDL Injection.
