Responsiveness to change of the Malay-ECOHIS following treatment of early childhood caries under general anaesthesia.

Objectives: To evaluate the sensitivity and responsiveness of the Malay version of Early Childhood Oral Health Impact Scale (Malay-ECOHIS) to dental treatment of early childhood caries (ECC) under general anaesthesia (GA) and determine the minimally important difference (MID) for the Malay-ECOHIS.

Methods: A sample of 158 preschool children with ECC awaiting dental treatment under GA was recruited over an 8-month period. Parents self-completed the Malay-ECOHIS before and 4 weeks after their child's dental treatment.
