      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: Patients are divided into two groups using blocks of six prepared by SPSS statistical software: in the first group, the first injection of anesthesia is performed on the right side of the jaw, and in the second group, the first injection of anesthesia is performed on the left side of the jaw. All injections will be performed by a maxillofacial surgeon in a room with an assistant. The use or non-use of anesthetic gel in the first injection will be randomly selected, Blinding description: First, SPSS statistical software randomly selects which side of the jaw of the local anesthetic is applied first in each patient. Therefore, it is determined which side is selected as the control group and which side is the case group, and the anesthetic gel is applied. Based on the injection site, we define two areas and place the desired anesthesia at that point. Due to the fact that a placebo is used in the control group, the patient will be blinded to the use or non-use of local anesthetic gel.</study_design>

      <i_freetext>Intervention 1: Intervention group: injection of local anesthesia along with the use of local anesthetic gel. First, SPSS statistical software randomly selects which side of the jaw of the local anesthetic is applied first in each patient. Therefore, it is determined which side is selected as the control group and which side is the case group, and the anesthetic gel is applied. As a result, in the intervention group, after placing the local anesthetic gel, anesthesia injection is performed. Local anesthetic gel containing 20% ​​lidocaine from Prodofix brand and then injection of 2% Xylopen anesthetic containing 20 mg lidocaine and 12.5 mg epinephrine. The interval between 2 intervention and control sessions will be 2 weeks. Intervention 2: Control group: injection of local anesthesia using placebo. First, SPSS statistical software randomly selects which side of the jaw of the local anesthetic is applied first in each patient. Therefore, it is determined which side is selected as the control group and which side is the case group, and the anesthetic gel is applied. As a result, in the control group, anesthesia injection is performed after placing the placebo substance. Vaseline petroleum jelly is used as a placebo, and then the injection of 2% xylopen anesthetic containing 20 mg of lidocaine and 12.5 mg of epinephrine is performed. The interval between 2 intervention and control sessions will be 2 weeks.</i_freetext>
