The Effect of Molar Incisor Hypomineralisation on the Stomatognathic System

Non-invasive diagnostic imaging techniques used to assess the stomatognathic system. Ultrasound was performed to measure the thickness of the masseter, temporalis, and sternocleidomastoid muscles, as well as the articular disc of the temporomandibular joint. Shear Wave Elastography was used to evaluate the elasticity (stiffness) of the same muscles and joint structures in kilopascals. All evaluations were conducted at rest, using standardized positioning, and by the same experienced operator.
