Objective To describe the development and application of the Assessment of Clinical Oral Risks and Needs (ACORN) stratification tool based on a traffic light system in National Health Service (NHS) general dental services (GDS) Wales, UK. Materials and methods This was a secondary analysis of routinely-collected dental care data. All courses of treatment provided in dental practices participating in NHS GDS Reform Programme between July 2018 and September 2019, in which an ACORN assessment and age were recorded were included in the analysis. Results A total of 236,490 subjects contributed 339,933 courses of treatment during the study period. ‘Amber’ and ‘red’ ACORN outcomes were associated with more courses of treatment per annum than ‘green’ outcomes. Outcomes indicating an increased risk of decay or other dental problems were associated with a greater likelihood of several operative treatment items. Patients at greater risk of poor periodontal health were more likely to receive extractions and dentures than low-risk patients. Patients were most likely to either remain in the same ACORN outcome categories or move to a healthier state between assessments. Conclusion More research is required to understand the utility of the ACORN tool in risk communication and behaviour change.
