MetadataShow full item record
Background: Early childhood caries is the most common childhood disease in preschool children which often requires dental treatment under restorative dental general anaesthesia (RDGA). Aim: To assess the efect of RDGA on preschool children and their families’ oral health-related quality of life (OHRQoL). Methods: A cross-sectional study using a RDGA pre- and post-operative survey to evaluate changes in OHRQoL. Parents completed the Early Childhood Oral Health Impact Scale (ECOHIS) survey before and after their children underwent specialist paediatric RDGA in the United Arab Emirates from 1 March 2017 to 28 February 2018. The ECOHIS and its efect size (ES) served to evaluate children’s OHRQoL status and changes, and the Wilcoxon signed-rank and the Kruskal-Wallis tests were used for statistical analyses. Results: The mean number of decayed, missing and flled teeth (DMFT) of the children (N = 173, mean age 4.6 years) before the treatment was very high (13.8 ± 3.07). Children’s pain and eating problems, and parents feeling upset and guilty, were the most frequently reported impacts at baseline. The ECOHIS scores decreased signifcantly (p <0.001) after RDGA, revealing a large ES for the child (2.19) and family (2.79) sections of the ECOHIS. Conclusions: Preschool children’s RDGA resulted in signifcant improvement in all child and family physical, psychological and social aspects of OHRQoL.
