comprehensive dental treatment
OtherEarly treatment children were scheduled for comprehensive dental treatment over a 2-month period (from May to June 2007). All test children had their last dental treatment visit within the last 2 weeks of the second treatment month. The follow-up survey was scheduled for each child to be approximately 6-month after their dental last visit. This step was very important to make sure that all children were examined at exactly the same interval between end of treatment and when re-examined at the follow-up examination.
