Assessment of Effectiveness Acceptability Complications and Parental Satisfaction of Pediatric Dental Patients Treated under Nitrous Oxide-oxygen Inhalational Sedation Using Porter Silhouette Mask.

Objectives: To estimate the concentration of nitrous oxide (NO) required for effective sedation to render dental treatment for an anxious child and to assess the child's behavior, patient acceptance, parental satisfaction, postoperative complications, and ease of manipulation of Porter Silhouette mask by the dentist during NO-O sedation.

Study Design: A total of 40 children, 6-10-year-old requiring dental treatment, were treated using NO sedation. The level of NO required for optimal sedation, patient behavior, level of acceptance of NO by the patient, clinical recovery score, and postoperative complications were observed throughout the study.
