Pain experience after conventional, atraumatic, and ultraconservative restorative treatments in 6- to 7-yr-old children

Abstract

The hypothesis was tested that the level of pain experienced by children during conventional restorative treatment is higher than during atraumatic restorative treatment (ART) or an ultraconservative treatment. The sample consisted of 244 children, 6- to 7 yr of age, who had at least two teeth with dentine carious lesions. Before the first treatment session (Tx-1), in which one of the carious teeth was treated using one of the treatments, the level of dental anxiety was assessed using the Facial Image Scale (FIS). The child reported the intensity of pain experienced during the procedure using the Wong-Baker FACES Pain Rating Scale. When conventional restorative treatment was used, more children needed local anaesthesia. Analyses excluding the data of children who had received local anaesthesia showed no treatment group effect on the Wong-Baker score, a FIS Tx-1 effect on the Wong-Baker score, and a statistically significant correlation between FIS Tx-1 and Wong-Baker scores. There was no significant difference in the pain levels of children treated using conventional restorative treatment, atraumatic restorative treatment or ultraconservative treatment. Local anaesthesia had to be administered more frequently to children in the conventional restorative group than to those in the other two treatment groups.
