Oral health professional curricula require continuous evolution to meet the needs of the population. The development of existing curricula to incorporate new topics is rarely considered in the dental education literature, and practical guidance will support educators in achieving changes locally. This paper aimed to present an evidence-based curriculum development model grounded in current dental and oral health professional education practices. To illustrate and validate this model, the integration of environmental sustainability (ES) into the curriculum will be used as a case study, offering practical insights into a real-world curriculum development process.
