This randomized split-mouth clinical trial evaluates whether computer-controlled intraosseous anesthesia delivered with the SleeperOne® 5 system reduces pain perception and dental anxiety compared with conventional local anesthesia during restorative treatment of children with molar-incisor hypomineralization (MIH). Thirty-five children received both anesthesia techniques in separate treatment sessions. Pain perception, behavioral responses, dental anxiety, pulse rate, and oxygen saturation were assessed at predefined time points.
Molar-incisor hypomineralization (MIH) is a developmental enamel defect that frequently presents with hypersensitivity, post-eruptive enamel breakdown, and an increased risk of restorative treatment failure. Achieving effective local anesthesia in children with MIH can be challenging because hypersensitive teeth often exhibit increased pain during anesthetic administration and restorative procedures. These factors may compromise patient cooperation and the quality of dental treatment. Computer-controlled local anesthetic delivery systems have been developed to improve injection comfort by controlling the rate and pressure of anesthetic administration. The SleeperOne® 5 system allows computer-controlled intraosseous anesthesia and may provide more effective pain control than conventional local anesthesia during restorative treatment of MIH-affected teeth. The purpose of this study was to compare SleeperOne® 5-assisted intraosseous anesthesia with conventional local anesthesia in children undergoing restorative treatment of permanent first molars affected by MIH. The study was conducted as a randomized split-mouth clinical trial in which each participant received both anesthetic techniques during separate treatment sessions. The order of the interventions was determined using computer-generated randomization, allowing each participant to serve as his or her own control. All clinical procedures were performed under standardized conditions by the same operator. The study was designed to evaluate whether computer-controlled intraosseous anesthesia could improve pain control and patient comfort during restorative treatment of children with MIH compared with conventional local anesthesia.

Pain Perception During Anesthetic Administration
Pain intensity during local anesthetic administration assessed using the Visual Analog Scale (VAS), a 10-cm scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores indicate greater pain intensity.
Time frame: Immediately after completion of local anesthesia administration (T1)
Behavioral Pain Response
Behavioral pain response assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. The FLACC Scale ranges from 0 to 10, with scores of 0 indicating no pain-related behavioral distress and scores of 10 indicating severe pain-related behavioral distress. Higher scores indicate greater pain-related behavioral distress.
Time frame: Immediately after completion of local anesthesia administration and immediately after completion of the restorative treatment procedure.
Dental Anxiety
Dental anxiety assessed using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). The CFSS-DS score ranges from 15 to 75, with higher scores indicating greater dental anxiety.
Time frame: Immediately before local anesthesia administration, immediately after completion of local anesthesia administration, and immediately after completion of the restorative treatment procedure.
Pulse Rate
Physiological response assessed by pulse rate (beats per minute)
Time frame: Before local anesthesia administration (T0), immediately after local anesthesia administration (T1), and immediately after restorative treatment (T2).
Peripheral Oxygen Saturation (SpO₂)
Physiological response assessed by peripheral oxygen saturation measured by pulse oximetry as a percentage (%). Higher values indicate greater oxygen saturation.
