Table 3 Children scoring below Minimal Important Difference (MID) and change scores for differences among scores of the Early Childhood Oral health Impact Scale (ECOHIS) at the baseline and 30 days after finishing the dental treatment considering some independent variables (n = 152)

From: Responsiveness of the Early Childhood Oral Health Impact Scale (ECOHIS) is related to dental treatment complexity
