Single-Agent Sedation for Behavioral Management in Pediatric Dentistry: An Umbrella Review of Agents, Routes of Administration, Providers, and Clinical Settings.

Background: Dental fear and anxiety are highly prevalent in children, resulting in avoidance or incomplete dental treatment; sedation emerges as a possible behavioral management strategy. This umbrella review aimed to provide a structured and critical synthesis of the available knowledge on sedative single-agent efficacy and routes of administration employed for achieving sedation (excluding deep sedation/general anesthesia) during dental procedures in children for behavior management, as well as to evaluate acceptability and satisfaction for child, caregiver, and provider, and to assess the influence of clinical setting and provider. Methods: In line with the PRISMA statement, the protocol was registered on PROSPERO (CRD420251043738), and 18 systematic reviews were included and synthesized qualitatively. Results: Single-agent sedation was safe and effective for managing behavior in children during dental procedures, with midazolam and nitrous oxide being the most studied agents. Different routes of administration showed distinct characteristics in onset, recovery time, adverse effects and cooperation, while agent selection appeared influenced by clinical setting and provider type. However, data on acceptability and satisfaction from children, caregivers, and providers remains limited. Conclusions: Evidence suggests potential effectiveness of selected agents and routes in appropriately monitored settings, but data heterogeneity precludes strong comparative recommendations. Further studies are therefore needed to address the existing gaps in pediatric dental sedation.
