Young children's Oral Health-Related Quality of Life and dental fear after treatment under general anaesthesia: a randomized controlled trial.Eur J Oral Sci. 2009 Jun; 117(3):273-8.EJ
During the past decade the research interest in Oral Health-Related Quality of Life (OHRQoL) has been prospering. This study was performed to test (using a randomized controlled trial design) the hypothesis that young children's OHRQoL improves after oral rehabilitation under general anaesthesia (GA). A further aim of this study was to explore whether dental fear also changes. One-hundred and four children (54 boys; mean age 4.08 yr, standard deviation = 1.09), who had been referred to a specialized clinic in paediatric dentistry, were randomly assigned, based on a Solomon four-group design, to two treatment (GA) and two control conditions. The Early Childhood Oral Health Impact Scale (ECOHIS) and the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) were used to assess OHRQoL and dental fear, respectively, before and after the rehabilitation procedures. A 2 x 2 analysis of variance revealed that the total ECOHIS score after GA was more positive in the GA group than in the control group. There was no effect found of the pre-test and there was also no interaction between the pre-test and treatment. In the total CFSS-DS scores no effects were found. The results of this study showed that the child's OHRQoL improved after treatment under GA. Furthermore, children need guidance in reducing dental fear after treatment under GA.
