[Assessment of application of computerized local anesthetic delivery system in periodontal ligament injection]
1Department of Oral and Maxillofacial, Ninth People's Hospital, Shanghai Second Medical University, Shanghai 200011, China.
Objective:
To assess the pain intensity and anesthetic effect in peridontal ligament injection using the computerized local anesthetic delivery system made by Milestone company in USA.
Methods:
40 cases were selected,and comparing the periodontal ligament injection through using the computerized local anesthetic delivery with traditional manul local anesthesia.
Results:
By using the computerized local anesthetic delivery system the pain in peridontal ligament injection was significantly less than traditional methods. There was no difference in anesthetic effect when teeth were extracted.
Conclusion:
The peridontal ligament injection usually as an adjunctive anesthesia method could attain good anesthetic effect and would have a wide application by using the computerized local anesthetic delivery system.
