RESULTS
A total number of 46 children, 22 boys and 24 girls,participated in the study and allocated between Tell-Show-Do (n = 23) and Filmed modeling (n = 23)groups.
At the first visit, a child in Group I showed definite negative behavior of score level I based on Frankle index and was excluded from the study.
Data revealed that both groups were the same in demographic characteristics including their sex, mean age, parental education and age, parental dental experiences, number of children in the family, and participation in kindergarten.
Table 3 shows the mean and standard deviation (SD) for the heart beat rate, anxiety level, and cooperative behavior of children during treatment in two groups.
Accordingly, heart rate mean scores(before and after local anesthesia injection) showed no signifi cant differences between two groups (P = 0.6).
Moreover, there were no statistically signifi cant differences for the anxious and cooperative behavioral mean scores between two groups (P > 0.05).
