Methods: DGA was explained to 299 surveyed subjects (mother or father), and then the questionnaires were filled in. Parental acceptance rate were determined by a 100mm visual analogue scale (VAS). At the left end of the line appeared the words "completely acceptable" (0mm); at the right end of the line appeared the words "completely unacceptable" (100mm). Each parent placed a mark on the horizontal line at a point corresponding to their personal acceptance rating of the DGA technique. The acceptance rating of DGA was determined by measuring the distance on VAS line from the left end to the marked point by the subject. SPSS13.0 software was used for statistical analysis.
Results: Spearman correlation analysis demonstrated that there were no correlation between the DGA acceptance rate and the age of child, the age of the parents, educational level, and the frequency of dental visit for the child. For the surveyed mother, acceptance rate of DGA was positively related with the monthly income (r=0.21,P<0.05) and was negatively related with the evaluated score of child cooperation degree( r=-0.137,P<0.05).
Conclusions: There was no correlation between the DGA acceptance rate and the age of child, age of parents, educational level and frequency of dental visit for the child. There were different considerations for mother and father when choosing DGA. The major influence factors for mother to accept DGA was the income level and the status of children's cooperation. Adequate explanation of DGA to both father and mother should be emphasized. Family income may be the most important factor for the lower acceptance rate of DGA at the present.
