Temporomandibular dysfunction is a pathological entity related to functional problems affecting the joint, masticatory muscles and associated structures. Currently its incidence is increasingly common in children and adolescents, so it is necessary to identify the factors related to the functional status of the temporomandibular-mandibular joint. A descriptive, cross-sectional and correlational research was carried out with a sample of 67 adolescents from 14 to 18 years of age, finding that TMJ is more prevalent in females, regardless of age. Overpassing, slipping from centric relation to maximum intercuspidation position, lateral occlusal interferences and stress are associated with TMD and its symptoms.
