title: [Effect of pretreatment education of the guardians of children's behavior during dental treatment].
abstract: OBJECTIVE
  To assess the effect of the pretreatment education of the guardians on the children's and guardian's behavior during dental treatment.
  
  
  METHODS
  The study group included 235 children aged 2-8 years who received dental treatment in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology. Interviews were conducted with accompanying guardians to collect information of children and their guardians, including parent's Corah Dental Anxiety Scale. The guardians were randomly divided into two groups. Group I was control group in which the guardians received a pamphlet about how to clean children's teeth, group II was the education group in which the guardians received a pamphlet about how to help a child to cooperate with the dentist during dental treatment. Children's heart rate was recorded at different time points: before the treatment, at local anesthesia (LA), during the treatment and at the end of the treatment. Children's dental behavior was rated by a modified Venham's clinical anxiety scale and a cooperative behavior rating scale. The guardian's tension was sorted into four levels and the characteristics of their language were recorded.
  
  
  RESULTS
  Among the 235 children, 131 were boys and 104 were girls with mean age of 4.35 years, and 165 children were treated under LA. The group I included 129 children and 95 children were treated with LA. The group II included 106 children and 70 children were treated with LA. The children's behavior in group II was better than that in group I(χ(2)=4.56, P=0.033). The guardians in group II were more relaxed than in group I at all the four times points: Beginning (Z=-2.581, P=0.01), LA (Z=-3.613, P=0.002), Treatment (Z=-3.096, P=0.002), Whole (Z=-3.042, P=0.002); and more positive language were used in group II at three times points: LA (χ(2)=15.57, P<0.001), Treatment (χ(2)=6.52, P =0.011) and Whole (χ(2)=15.99, P<0.001).
  
  
  CONCLUSIONS
  An education for guardians before dental treatment may improve children's dental behavior and guardians' tension in dental treatment.
