Overview
Brief Summary
The aim of the study is to evaluate the effect of nebulized Midazolam, Dexmedetomidine, and their combination as procedural, moderate sedative agents in preschoolers undergoing dental treatment.
Detailed Description
Dental anxiety and fear related behaviors are global problems in Pediatric Dentistry. Preschoolers represent a dental behavior management problem and there is always a debate over the best behavioral management technique for preschoolers undergoing dental treatment. Moderate sedation is considered as an acceptable option. Children who need treatment under local anesthesia, for thirty minutes will be included in the study. A total of 72 uncooperative pediatric dental patients, of age range 4-6 years, will be selected from the Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, Egypt. The participants will be randomly allocated into 3 groups that will undergo a procedural sedation session via a nebulizer. Children of group I will receive nebulized solution of 0.5 mg/kg Midazolam, Group II will receive nebulized solution of 5µg/kg Dexmedetomidine, and Group III will receive a nebulized solution of 0.3 mg/kg Midazolam and 3µg/kg Dexmedetomidine respectively.

Arms & Interventions
Midazolam group (MDZ)
Twenty four pediatric dental patients will receive a procedural sedation session, using Nebulized solution of 0.5 mg/kg Midazolam.
Intervention: Midazolam group (MDZ)
Dexmedetomidine group (DEX)
Twenty four pediatric dental patients will receive a procedural sedation session, using Nebulized solution of 5µg/kg Dexmedetomidine.
Intervention: Dexmedetomidine group (DEX)
Combination of Midazolam and Dexmedetomidine (MDZ/DEX)
Twenty four pediatric dental patients will receive a procedural sedation session, using Nebulized solution of 0.3 mg/kg Midazolam, and 3µg/kg Dexmedetomidine respectively.
Intervention: Combination of Midazolam and Dexmedetomidine (MDZ/DEX)
Outcomes
Primary Outcomes
Post-operative effects of the sedation
Time Frame: immediately after completion of the dental treatment procedures.
This will be assessed according to Modified Vernon et al.
Analgo-sedative effect of each drug
Time Frame: during the sedation procedure (from its onset till meeting discharge criteria)
The duration of sedation: defined as the onset of satisfactory sedation until the time of meeting discharge criteria according to the American Academy of Pediatric Dentistry.
Facemask acceptance during drug delivery
Time Frame: during the sedation procedure
It will be evaluated according to Zanaty \& Metainy as: poor (terrified, crying and combative), fair (moderate fear of mask not calmed with reassurance), good (slight fear of mask, easily reassured) or excellent (unafraid, cooperative and accepts mask readily)
Effect of sedation on children's future behavior
Time Frame: after one week in the follow-up session
Each child's behavior will be reassessed in the follow-up sessions and compared to that at baseline (before dental treatment) using Frankl scale (ranges from 0-4)
The 'ease of treatment completion' sing separate five-point scales.
Time Frame: immediately after completion of the dental treatment procedures.
This will be measured using separate five-point scales according to Surendar et al: Score 5 indicates an excellent quiet and cooperative child while score 1 indicates Prohibitive active resistance and crying; treatment cannot be rendered.
Analgo-sedative effect of each drug.
Time Frame: during the sedation procedure (from its onset till meeting discharge criteria)
Assessment of the most common procedural side effects such as (hypoxia, respiratory depression, agitation, arrhythmia, bradycardia, hypotension or hypertension, shivering, nausea and vomiting) will be recorded.
Amnesic effect of sedative agents.
Time Frame: immediately after completion of the dental treatment procedures.
Anterograde amnesia: will be assessed according to a modification of Bulach et al.
Hemodynamic response of sedative agents.
Time Frame: during the sedation procedure (from its onset till meeting discharge criteria)
Vital sign: Oxygen saturation will be monitored using an oximeter
