This prospective observational study aims to evaluate the effects of different local anesthesia techniques on dental anxiety and pain in children undergoing vital pulp therapy of permanent mandibular first molars. Conventional inferior alveolar nerve block and two computer-controlled local anesthetic delivery (CCLAD) systems used in routine clinical practice will be compared. The choice of anesthesia technique will be based on the clinician's routine decision-making, and no additional intervention or modification of standard treatment will be performed for research purposes. Dental anxiety, pain, physiological parameters, and postoperative complications will be assessed using validated clinical scales and routine clinical measurements. The findings may help improve pain and anxiety management during pediatric dental treatment while supporting evidence-based selection of local anesthesia techniques.
