Abstract

Many approaches to local anesthesia have been studied in dentistry. In this study, we introduce a new local anesthetic method, "Point-Inject Technique (PIT)", and compare it with traditional injection techniques. The PIT method utilizes both the vasoconstrictive and antinociceptive properties of local anesthetics as well as the application of controlled pressure during injection, reducing the time to complete anesthesia. Fifty patients were selected as the experimental group who were anesthetized using PIT, and the other 50 patients were selected as the control group using the direct injection method with a carpool syringe. The PIT group received 0.25 cartridges of 2% lidocaine with 1:100,000 epinephrine. The control group received 1.5~2 cartridges of 2% lidocaine with 1:100,000 epinephrine. Both groups were asked to mark the intensity of the pain caused by anesthesia using the Numeric Pain Rating Scale. The average time to recover from anesthesia was 40 minutes in the experimental group and 90 minutes in the control group. Additionally, 96% of the experimental group reported feeling no pain, while 78% of the control group reported having some form of pain during injection. The PIT method reduced both the reported pain scores of patients as well as time to recover from local anesthesia than the widely-used syringe injection method.
