Juvenile Idiopathic Arthritis (JIA) is a chronic inflammatory condition that affects the jaw joints, leading to symptoms such as jaw pain, stiffness, swelling, and difficulty in jaw movement. In individuals with JIA, the inflammation in the jaw joints can cause changes in the structure and function of the jaws, potentially affecting bite alignment, facial growth, and overall oral health. Treatment approaches for JIA in the jaw may include medications, physical therapy, and in some cases, surgical interventions to manage the symptoms and preserve jaw function. It is also referred to as Juvenile Rheumatoid Arthritis.
