Aim: A brief review of epidemiologic studies of signs and symptoms in children and adolescents. The principles and methods of management of patients with temporomandibular disorders are then presented with a special focus on children and young patients. Methods: The presentation is based, as much as possible, on current evidence-based literature but may especially reflect Scandinavian experiences and research. The article includes three case presentations of diagnosis and management of children with temporomandibular disorders. Results and Conclusions: Epidemiologic research has demonstrated that signs and symptoms are relatively common in children and adolescents; however, they generally occur with lower prevalence, are more often occasional, and are of a milder character than in adults. Mild and infrequent temporomandibular disorder signs and symptoms do not always need to be treated. When treatment is necessary, most children and young patients with temporomandibular disorders respond quickly to simple, conservative methods, such as counseling, jaw exercises, and interocclusal appliances.
