Effect of Local Anesthesia Techniques on Pulp Hemostasis in Primary Molars

The goal of this clinical trial is to compare the effects of two local anesthesia techniques on pulp hemostasis time during pulpotomy treatment of mandibular primary molars in children aged 6-9 years. The main questions it aims to answer are: Does the local anesthesia technique affect the time required to achieve pulp hemostasis during pulpotomy? Are there differences between the two anesthesia techniques in terms of pain, heart rate, and oxygen saturation during treatment? Researchers will compare conventional inferior alveolar nerve block anesthesia with computer-controlled intraosseous local anesthesia using the QuickSleeper 5 system to determine whether the anesthesia technique affects pulp hemostasis time and the secondary clinical outcomes. Each participant will receive both anesthesia techniques in a randomized order using a split-mouth design. Participants will: Receive conventional inferior alveolar nerve block anesthesia for pulpotomy treatment of one mandibular primary molar. Receive computer-controlled intraosseous local anesthesia using the QuickSleeper 5 system for pulpotomy treatment of the contralateral mandibular primary molar at a separate treatment session. Have pulp hemostasis time recorded during each pulpotomy procedure. Have pain, heart rate, and oxygen saturation assessed during the treatment procedures.
