Sleep is essential for maintaining a good physical and mental health. Unfortunately, sleep quality can be disturbed by numerous factors, including the occurrence of sleep disorders. While such disorders should be diagnosed and managed by medical specialists, some sleep disorders are linked to dentistry. The dental discipline “Dental Sleep Medicine” (DSM) deals with dental sleep disorders. DSM encompasses not only sleep-breathing disorders, as was traditionally the case, but also conditions like mandibular movement disorders (e.g., sleep bruxism, SB), orofacial pain (OFP), and sleep-related gastro-esophageal reflux (GER). In everyday clinical practice, these conditions occur only seldom in isolation. More frequently, they occur as comorbid conditions. In this symposium, four renowned experts will guide the attendants through one of many possible series of links between the dental sleep disorders, starting with OSA, via OFP, SB, and GER, back to OSA. Each presenter will focus on the mutual links between two dental sleep disorders, thereby passing one of those through to the next presenter. In short, the first presenter will discuss the links between OSA and OFP, the second between OFP and SB, the third between SB and GER, and the fourth between GER and OSA. As such, the presenters will sketch the circle of dental sleep disorders.
