title: [Influence of the effect of general anaesthesia and restraint during dental treatment on dental anxiety and behavior in children].
abstract: OBJECTIVE
  To compare the level of dental anxiety and dental behavior between dental fear children with dental treatment under general anaesthesia (GA) and those under restraint.
  
  
  METHODS
  The GA group included 31 dental fear children aged 4-6-year-old who received dental treatment under the GA. The restraint group included 31 dental fear children aged 4-6-year-old who received dental treatment under the restraint. Age, gender, parent's education level, decayed-missing-filled-tooth (dmft) and face version of the Modified Child Dental Anxiety Scale (MCDASf) score before treatment were matched between the two groups. The Chinese version of MCDASf was used to evaluate the level of dental anxiety in each child before treatment, right after treatment and before examination at recall visit 2-3 weeks after treatment. And the Chinese version of Venham Clinical Anxiety and Cooperative Behavior Scale was used to evaluate children's dental behavior in each child before treatment and before examination at recall visit 2-3 weeks after treatment.
  
  
  RESULTS
  The average scores of MCDASf in GA group right after treatment and before recall were lower than that before treatment. The difference was statistically significant (P<0.05). Furthermore, the average score of MCDASf before recall was lower than those after treatment, and the difference was statistically significant (P<0.05). The average scores of MCDASf in restraint group right after treatment and 2-3 weeks after treatment were higher than those before treatment, but the difference was not statistically significant (P>0.05). Children's dental behavior was significantly improved at recall visit in both groups (P<0.01).
  
  
  CONCLUSIONS
  Dental fear could be reduced by treatment under GA. The children's dental behavior was improved after GA. Restraint did not result in the significant elevation of dental anxiety level, but dental behavior was improved after restraint during the short-term recall.
