Periodontal ligament injection: a clinical evaluation
Journal of the American Dental Association (1939)
|October 1, 1981
Summary
The periodontal ligament injection is a highly effective supplementary technique for achieving profound local anesthesia, with a 92% success rate. Proper technique, particularly injecting under strong pressure, is crucial for optimal results in dental procedures.
Area of Science:
- Dentistry
- Anesthesiology
Background:
- Achieving profound local anesthesia can be challenging with standard dental injection techniques.
- Supplementary anesthesia methods are often required for adequate pulpal anesthesia.
Purpose of the Study:
- To evaluate the effectiveness of the periodontal ligament injection as a supplementary technique for patients lacking adequate pulpal anesthesia.
- To identify factors influencing the success rate and onset of anesthesia.
Main Methods:
- A questionnaire was administered to 120 patients following periodontal ligament injections.
- Data collected included frequency and rapidity of anesthesia onset, and influencing factors.
Main Results:
- The periodontal ligament injection achieved an overall success rate of 92%.
- Injecting under strong backpressure was critical for success, especially on mesial and distal surfaces.
- Mandibular molars required supplementary anesthesia more often than other teeth.
- Anesthesia onset was typically immediate.
Conclusions:
- The periodontal ligament injection is a highly effective supplementary method for achieving profound local anesthesia.
- Strong injection pressure and resistance are key factors for successful outcomes.
- This technique offers a reliable solution when standard injections fail to provide adequate anesthesia.
