Abstract：Objective To explore synergistic effect of music therapy and nitrous oxide inhalation sedation for child dental fear(CDF) in children with CFSS-DS grade of 4 or above.Methods A total of 60 children in need of oral treatment (aged 4-10 years)were included in the study,who were classified as severe CDF by children's fear survey schedule-dental subscale(CFSS-DS)at Department of Pediatric Stomatology in General Hospital of PLA from December 2015 to December 2016.The children were randomly selected to accept music therapy and nitrous oxide inhalation (the experimental group),or nitrous oxide inhalation only (the control group),30 children in each group.Heart rate,blood pressure and oxygen saturation were recorded before treatment,before using nitrous oxide inhalation and during treatment.Sedation onset time,treatment duration and recovery time were also recorded.Results In the control group,21 children completed treatment,while 9 children stopped the treatment due to fear.In the experimental group,26 completed the treatment while 4 stopped.The onset time of nitrous oxide and duration of operation in the experimental group were significantly less than the control group.In the course of therapy,children in the experimental group possessed emotional homeostasis and good conpliance.Their heart rate and systolic pressure in operation were not significantly increased,and even significantly reduced.The diastolic pressure and oxyhemoglobin saturation had no significant change.Conclusion Nitrous oxide inhalation and synergistic effect of music therapy has significant effects on children with CFSS-DS grade of 4 or above.It can improve patient compliance and is a safe and acceptable approach for behavior management of children with CDF.
