| According to the survey the incidence of dental fear is more than 80% among our children. It affects seriously on the accurate and timely in diagnosis and treatment of children's oral diseases, and harms the body and mental health of patients, so it becomes enormous work pressure to pedodontists. How to deal with children's DF effectively becomes an important task as a pedodontist.Currently basic psychological and behavioral induction is the main treatment for DF children in China. Binding plate fixation is commonly used to the invalid basic psychological and behavioral induced children. Children's physical and mental health is easily and badly affected due to forced treatment.IHS is commonly used to the invalid basic psychological and behavioral induced children in Europe and America. Sedation oral therapy in children is still in its infancy in China. IHS has not been widely used in children dentistry. In this study, IHS assisted with the psychological and behavioral induction was used to DF children's dental therapy, and its efficacy was analyzed and evaluated.Purpose:To evaluate the effectiveness and safety of IHS in children who suffer from the anxiety and fears during their tooth treatment and to provide a new support measure to improve the cooperative oral treatment of DF children, so as to improve the treatment quality and efficiency in DF.Method:64 DF cases treated in Jinan stomatologic hospital that cannot be treated under normal conditions were chosen as the subject in this study. The cases were divided into two groups, one was experimental group, and the other was control group,32 cases were in each group. Experimental group was treated under the condition of IHS. Control group was treated only under the condition of psychological and behavioral induction. CFSS-DS score of experimental group and control group was recorded. And T-test comparison between groups was conducted. Sedative onset time, nitrous oxide/oxygen application concentration, duration of treatment, recovery time, patients pulse, oxygen saturation, complete treatment and adverse reactions of experimental group were recorded in the treatment. And Venham clinical anxiety and cooperative behavior level of experimental group and control group children were recorded too. The behavior change of the experimental group and control group and group differences conducted rank sum test analysis. Parents'satisfaction with treatment and children's cooperation in referral were recorded.Results:①In the experimental group,28 patients achieved good effect and successfully completed the treatment by nitrous oxide/oxygen inhalation sedation. Sedative effect of 4 cases were poor, binding plate fixation were used to complete the treatment. So the treatment rate was 87.5%. In the control group,20 patients completed the treatment as expected,10 cases were completed the treatment by binding plate fixation, the other 2 cases gave up the treatment because of their parents'disagreement,the treatment rate was 62.5%. The treatment efficiency between two groups were significantly different (p<0.05)②After treatment, the average score of CFSS-DS was lower than before treatment, score of experimental group was lower than that of the control group, The control difference between the two groups and in group was statistically significant (p<0.05)③Two groups level score of Venham clinical anxiety and cooperative behavior declines in the treatment entire process, the experimental group decreased more significantly than in the control group (p<0.05)④After treatment, parent satisfaction was 93.75% in the experimental group, it was 71.88% in the control group. ⑤One week later referral after treatment, .9% of patients took the initiative to co-treatment in the experimental group, it is 48% in the control group.⑥uring experimental group received nitrous oxide/oxygen inhalation, the concentration of nitrous oxide maintained 30-45%,the flow of Output gas was 4.8-6.5L/min, oxygen saturation was 96-100%, pulse is72-123 beats/min, onset time of sedation to effective was 6.44±1.29 min, treatment time was 12.43±4.71 min, recovery time was 2.49±0.39 min. All patients had no side effect.Conclusion:①IHS is effective to relieve anxiety and fear in the treatment, to improve behavior in treatment and to improve cooperative in the oral treatment.②IHS is safe to children without obvious adverse reactions.③In IHS application process, children age, underlying anxiety, personality traits, may constitute important factors affecting IHS effects. It should be carefully chosen in clinical indications.④In clinical treatment, the primary of basic psychological and behavioral induction and the importance of painless treatment should be emphasized, IHS only is an effective assistance during basic behavior management in children dental.⑤IHS assisted with the psychological and behavioral induction can obtain a higher parents satisfaction. |
