Summary of findings 2. Sedative compared with different dosage of the same sedative for children needing dental care.

Sedative compared with different dosage of the same sedative for children needing dental care
Patient or population: children needing dental care
 Setting: hospital
 Intervention: sedative
 Comparison: different dosage of the same sedative
Outcomes Number of participants
 (studies) Certainty of the evidence
 (GRADE) Comments
Any behavioural score ‐
Midazolam (any mode of delivery)
394 (10) ⊕⊝⊝⊝
 VERY LOW1 There is insufficient evidence to determine whether any specific dose of intranasal midazolam is effective
There is weak evidence from two trials that oral midazolam at a dose of 0.5 mg/kg to 0.75 mg/kg is an effective sedative for children. However, one trial administered both nitrous oxide and midazolam so it is difficult to attribute benefit to midazolam alone
Any behavioural score ‐
Hydroxyzine
30 (1) ⊕⊝⊝⊝
 VERY LOW1 There is insufficient evidence to determine whether any specific dose of hydroxyzine is effective
GRADE Working Group grades of evidenceHigh certainty: we are very confident that the true effect lies close to that of the estimate of the effect.
 Moderate certainty: we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different.
 Low certainty: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect.
 Very low certainty: we have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect.

1Downgraded for risk of bias, inconsistency and/or imprecision.
