Jiang H, et al. - In children after treatment for early childhood caries (ECC) under dental general anaesthesia (DGA) in Chongqing, China, researchers conducted this single-centre prospective cohort study to assess the success rates of dental procedures, the recurrence rates of caries and changes in oral health-related quality of life (OHRQoL). The study sample consisted of 159 children (aged 2 to 5 years) who received treatment for ECC under DGA. Data reported that the resin composite, stainless steel crown, indirect pulp capping, pulpectomy, space maintenance and dental sealant success rates were 89.6%, 96.3%, 96.0%, 94.4%, 76.9% and 92.9%, respectively, at 6 months and 78.8%, 95.1%, 92.2%, 88.9%, 63.6% and 89.3%, respectively, at 12 months. Overall, high success rates for dental procedures were obtained, and after treatment, the OHRQoL of the children improved significantly. There was, however, a tendency to relapse of caries, and the OHRQoL of the children deteriorated over time.
