Abstract

Background: Pain and anxiety can be considerable obstacles while treating paediatric dental patients. Moderate sedation is needed to treat uncooperative patients.

Aim: This study aimed to compare the effectiveness of buccal administration of dexmedetomidine-ketamine combination versus dexmedetomidine.

Design: Fifty-six uncooperative children were randomly assigned into two groups: Group I received buccal dexmedetomidine (2 μg/kg) and ketamine (2 mg/kg) (DEX-KET), whereas Group II received buccal dexmedetomidine (4 μg/kg) (DEX). The effects of drugs were evaluated based on changes in vital signs, onset and duration of sedation, sedation level, analgesia, ease of treatment and procedural adverse effects.

Results: There were no significant differences in vital signs or sedation onset between the two groups. DEX-KET group showed shorter recovery time than DEX group (p < .0001). There were no statistically significant differences between both groups regarding sedation level at optimum sedation and during operative procedure (p = .064, p = .069 respectively). The ease of treatment was significantly better in DEX-KET group than in DEX group (p = .048). Procedural side effects and analgesic effects of the sedative drugs were comparable between both groups.

Conclusion: The combination of dexmedetomidine and ketamine delivered buccally provided a better method of delivering care to uncooperative children with more rapid recovery than dexmedetomidine.

Keywords: buccal; children; dexmedetomidine; ketamine; sedation.
