Obstructive Sleep Apnoea (OSA) is a highly prevalent disorder across the world and is characterised by repeated obstruction of the pharyngeal airway during sleep, resulting in oxygen desaturation (intermittent hypoxia) and sleep fragmentation. As awareness of the disorder has risen over the last few decades, there is growing recognition that OSA is a highly heterogeneous disorder, and that application of a precision medicine framework to its treatment could significantly enhance patient outcomes by allowing prediction of who has OSA, who needs it treated, who is susceptible to symptoms and comorbidities, which treatment should be used and who will respond to therapy. To achieve this, there is a need to develop an understanding of intermediate OSA phenotypes in terms of their contribution to disease pathogenesis, clinical and physiological expression and treatment responses. Recently, there have been an increasing number of studies using unsupervised (cluster) analytical approaches that have generated new insights, demonstrating the viability of a precision medicine approach in sleep medicine. These advances will undoubtedly influence the emerging field of dental sleep medicine, and dentists need to be aware of these developments.
