- Evaluating the quality of systematic reviews on pediatric sedation in dentistry : an umbrella reviewPublication . Marques, Carolina; Dinis, Mafalda; Machado, Vanessa; Botelho, João; Lopes, Luísa BandeiraSedation is a depression of a patient’s state of consciousness, induced by medications, that can reach different levels of intensity during a medical procedure. Conscious sedation produces a minimally depressed level of consciousness without impairment of the ability to maintain an open airway, of protective reflexes or of responses to verbal and physical stimulation. This umbrella review is aimed at critically assessing the available systematic reviews (SRs) and meta-analyses (MA) on sedation in children/adolescents. An electronic database search was conducted that included Pubmed-Medline, Web of Science, Cochrane, Scopus, Scielo, Embase, LILACS and TRIP and the scope of which extended until January 2023. The risk of bias (RoB) of SRs was analyzed using the Measurement Tool to Assess SRs criteria 2 (AMSTAR2). Of 998 entries, 37 SRs were included. In terms of methodological quality, eight studies were assessed as having critically low quality, four studies had low quality, nine studies had moderate quality, and sixteen were considered to be of high quality. Based on the current guidelines, the most employed drugs in pediatric dentistry for sedation are nitrous oxide and midazolam; however, the available evidence supporting their use is insufficient and of low/critically low quality. The combined technique is recommended (nitrous oxide (30–50%) + midazolam). The optimal dose of oral midazolam is 0.75 mg/kg. The level of methodological quality of SRs is expected to increase according to the results and future directions of this umbrella review.
- International guidelines on conscious sedation in pediatric dentistry : a comparative analysis and evidence mapping studyPublication . Marques, Carolina; Dinis, Mafalda; Botelho, João; Machado, Vanessa; Lopes, Luísa BandeiraConscious sedation is widely used in pediatric dentistry to manage dental anxiety, behavioral difficulties, and systemic diseases that compromise patient compliance with dental care. Despite its clinical importance, international recommendations vary considerably. Objective: To conduct a comparative analysis and evidence mapping of international clinical practice guidelines on conscious sedation in pediatric dentistry. Methods: A comparative guideline analysis and evidence mapping study was performed. Electronic searches were conducted in PubMed (MEDLINE), Scopus, EMBASE, Cochrane Database of Systematic Reviews, Web of Science, LILACS, SciELO, TRIP, and OpenGrey up to December 2023. Guidelines issued by recognized professional or governmental organization addressing conscious sedation in pediatric dentistry were included. Predefined domains were analyzed, including indications, contraindications, pharmacological agents, dosages, routes of administration, monitoring, discharge criteria, and professional training. Data were synthesized descriptively and graphically mapped to illustrate coverage patterns. Results: Twelve international guidelines were included. Complete convergence (100%) was observed in core safety domains, such as patient assessment, monitoring, and professional training. A high agreement was found for discharge criteria (91.67%) and contraindications (83.33%). However, substantial variability emerged in pharmacological protocols, with only 16.67% of guidelines providing comprehensive drug and dosage descriptions. Routes of administration and emergency equipment recommendations were inconsistently reported, appearing in 66.67% and 50% of guidelines, respectively. Conclusions: Although foundational safety principles are consistently addressed, significant heterogeneity persists in pharmacological and procedural recommendations. This variability may contribute to differences in practice and uncertainty among practitioners. Greater international harmonization of guidelines may improve consistency, enhance clinical decision-making, and strengthen patient safety in pediatric dental care. Clinical Relevance: Identifying areas of convergence and variability across international guidelines may support the development of more standardized sedation protocols and promote safer evidence-based clinical practice in pediatric dentistry.
