Sedation with 50% nitrous oxide/oxygen for outpatient dental treatment in individuals with intellectual disability

The objective was to investigate the effect of nitrous/oxygen in chronic pain. Seventy-seven chronic pain patients referred to dental treatment with conscious sedation with nitrous oxide/oxygen had their records included in this research. Data were collected regarding the location and intensity of pain by the visual analogue scale before and after the treatment. Statistical analysis was performed comparing pre- and post-treatment findings. It was observed a remarkable decrease in the prevalence of pain in this sample (only 18 patients still had chronic pain, p < 0.001) and in its intensity (p < 0.001). Patients that needed fewer sessions received higher proportions of nitrous oxide/oxygen. Nitrous oxide may be a tool to be used in the treatment of chronic pain, and future prospective studies are necessary to understand the underlying mechanisms and the effect of nitrous oxide/oxygen in patients according to the pain diagnosis and other characteristics.

Two Age Groups

Objectives: to investigate whether behavior during hydroxyzine administration predicts children's behavior during dental treatment and whether behavior during treatment is affected by the complexity of treatment. Materials and method: 118 children aged 2 to 6.5 years old were treated under conscious sedation with oral premedication (3.7 mg/kg of hydroxyzine in a concentration of 50mg/5 cc. hydroxyzine) and 50% nitrous oxide/oxygen sedation. Children were divided in two age groups: aged 2 to ≤ 4 years old, and aged 4 ≯ to 6 years old. Behavior during first examination; cooperation during premedication administration, cooperation during nitrous oxide nose-mask placement, behavior during dental treatment, treatment duration and complexity of treatment were recorded. Results: More children in the older group took the premedication willingly (p=0.026). Significant correlation (p=0.002) between behavior during examination and nitrous oxide mask acceptance was found in the older age group. No correlation was found regarding the cooperation during premedication intake and behavior during treatment within and between age groups. No statistical differences within the groups and between the groups were found between complexity of treatment and behavior during treatment. Conclusions: Premedication intake is not a reliable predictive tool for behavior during treatment in children aged 2-6.5 years. Complexity of treatment does not influence behavior during treatment in children aged 2-6.5 years.
