Clinical Evaluation and Comparison of Pain Acceptance of Different Types of Injection Systems

Application of Comfort-in Jet Injection Method Comfort-in jet injection method was used for palatal anesthesia of the primary molars. The device was placed 5 mm below the palatal gingival margin, close to the free gingiva, and with a steep angle. 0.2 ml of anesthetic solution was administered by pressing the jet injection system button. 1 mL Articaine Hydrochloride (Ultracaine D-S forte, Hoechst, Canada) containing 1/100,000 epinephrine was used as a local anesthetic agent in the injections. 38 patients were included in this group and the procedure was performed. After waiting for 2 minutes, the anesthetized area was probed with the help of a probe (probing gingiva) to check whether the anesthesia had taken effect. Afterwards, buccal infiltration anesthesia was performed with the help of a traditional dental injector and tooth extraction was performed.

Application of Traditional Dental Injection Method Palatal injection; It was applied 5-10 mm below the palatal gingival margin\*, on the attached gum, and with a 45-degree needle angle. After needle entry, 0.2 mL of anesthetic solution was stored when bone contact was removed. 1 mL Articaine Hydrochloride (Ultracaine D-S forte, Hoechst, Canada) containing 1/100,000 epinephrine and a 27 G dental needle were used as local anesthetic agents for injections. 38 patients were included in this group and the procedure was performed. After waiting for 2 minutes, the anesthetized area was probed with the help of a probe (probing gingiva) to check whether the anesthesia had taken effect. Afterwards, buccal infiltration anesthesia was performed with the help of a traditional dental injector and tooth extraction was performed.
