MDAS Modified Dental Anxiety Scale, SD standard deviation
- * Denotes the p value of two-tailed Pearson correlation coefficient <0.05; ** p value < 0.01; *** p value <0.001
-
aTwo-tailed paired t-test was performed from comparing between the ‘experience-based’ and the ‘imagination-based’ scores
-
bNormality was assessed according to the the Kolmogorov–Smirnov test for normal distribution; normality was accepted if p > 0.05. The patients’ age, the scores of dental avoidance, MDAS, and elicited fear conformed to normal distribution
-
cTwo participants did not complete the dental avoidance ratings based on imagination
