Findings: There was a significant decrease in the average score of DDQ after dental treatment. However, Pearson correlation showed that children whit palpotomy and crown during treatment or children with higher volume of treatment had higher score of DDQ than other children of study and still continued to difficulty with behaviors listed in DDQ. Conclusion: As regards children with high volume of dental treatment including various treatment (extraction, restoration, palpotomy, SSC) are candidate for general anesthesia, doing all the dental treatment in one session under general anesthesia cause the significant decrease in the score of DDQ the time after treatment.
