Pain-Related Behavior and Pain Perception Associated with Intraosseous Local Anesthesia (QuickSleeper 5®) in Pediatric Patients: A Randomized Controlled Clinical Trial.

Abstract

Background: Managing pain during dental procedures is crucial, particularly for children, as pain can induce anxiety. Local anesthesia is the most anxiety-inducing procedure in pediatric patients. Consequently, this study aimed to assess and compare the pain-related behaviors and perceptions associated with two anesthesia techniques for children: traditional local anesthesia and intraosseous local anesthesia administered via the QuickSleeper 5^® system.

Methods: A split-mouth randomized clinical trial was conducted involving 33 children aged 4-9 years. Each participant received both traditional local anesthesia and intraosseous local anesthesia with QuickSleeper 5 across two visits. Pain-related behaviors were evaluated by calibrated pediatric dentists through video recordings, and pain perceptions were assessed using the Wong-Baker Faces Pain Rating Scale. Heart rate measurements offered objective insights into patients' anxiety; finally, the time needed to administer anesthesia was recorded.

Results: This study found no statistically significant differences between traditional local anesthesia and intraosseous local anesthesia with QuickSleeper 5 regarding pain perception, heart rate, or pain-related behaviors, indicating that both techniques are effective at minimizing discomfort. However, QuickSleeper 5 demonstrated a significantly shorter administration time, enhancing the procedural efficiency of pediatric dentistry.

Conclusions: The QuickSleeper 5 system is a valuable tool for pediatric dental care, delivering comparable comfort levels to traditional anesthesia while significantly reducing the time that is required for administration. The QuickSleeper 5 system's efficiency advantage could make it the preferred choice for treating children, especially given the stress that is often associated with local anesthesia and the need for quick, smooth procedures in pediatric care.
