Using nitrous oxide inhalation sedation for classical conditioning - An evaluative study

Abstract

Purpose: This study was undertaken to evaluate conscious sedation as a means of classical conditioning for managing paediatric dental patients. Methods: A total of 20 healthy children (American Society of Anesthesiologists I) aged 5-9 years with positive and definitely positive Frankel behaviour rating scale were evaluated. In the first appointment (A 1) non-invasive treatment under nitrous oxide inhalation sedation was performed and oxygen saturation and pulse rate at 10%, 30% and 50% were recorded. In subsequent appointment (A 2) same treatment was executed under 100% oxygen and recordings were taken. Behaviour was assessed using comfort scale. Results: No significant difference was observed in pulse rate, oxygen saturation and visual analogue scale whereas scores of comfort scale showed significant results. Conclusion: Once behaviour modification to dental treatment is achieved, subsequent visit can be undertaken even without sedation, giving oxygen as a placebo where patient is sensitized to nasal hood resulting in positive dental behaviour.
