Oral Sedation With and Without Nitrous Oxide

Oral Sedation With/Without Nitrous Oxide in Pediatric Dental Patients

Aims: The objective of the current study was to evaluate the effectiveness of oral midazolam-hydroxyzine with/without nitrous oxide. Design: This was a randomized split mouth, cross over and triple-blinded clinical study. Thirty uncooperative healthy children aged six to nine, whose needed dental treatments.

The purpose of this study was to compare the efficacy of combining oral midazolam-hydroxyzine with/without N2O/O2 in sedating uncooperative schoolchildren undergoing dental treatment. Thirty uncooperative healthy children aged six to nine were randomly selected to receive either one tablet of oral midazolam 7.5 mg and one tablet of hydroxyzine 10 mg with 100% O2 (regimen A), or one tablet of oral midazolam 7.5 mg and one tablet of hydroxyzine 10 mg with 50% N2O/O2 (regimen B) in a crossover design. Behavior was assessed using the modified Houpt behavioral rating scale, by evaluating the videotapes of all patients at both the pretreatment phase (injection, rubber dam RD, operating high-speed handpiece with touching the tooth without drilling) and the treatment phase (drilling, restoration).

Criteria: Inclusion Criteria:

• ASA Classification I.
• minimum weight of 18 kg
• uncooperative children scored 1 or 2 on Frankle Scale.
• requiring nonemergency, bilateral mandibular dental treatments under local anesthesia.

Exclusion Criteria:

• known allergy to midazolam and/or hydroxyzine.
