Assessing dental anxiety in children: the Revised Smiley Faces Program

The findings demonstrate that the revised version of the computerized SFP-R is a reliable and valid tool for assessing dental anxiety in UK children from 4 to 11 years.• The SFP-R response set gives children the opportunity to provide positive as well, negative responses to dental procedures and contexts.• The children reported highest anxiety for the local anaesthetic and drill items, followed by the new tooth extraction item.
