[Juvenile idiopathic arthritis and oral health]

Juvenile idiopathic arthritis (JIA) is the most common autoimmune inflammatory disease of connective tissue in children. It is characterized by progressive joint destruction which causes preserved changes in the musculoskeletal system. The literature describes fully clinical symptoms and radiological images in different subtypes of JIA. However, there is still a limited number of studies reporting on the medical condition of the oral cavity of ill children. JIA can affect hard and soft tissues of the oral cavity by: the general condition of the child's health, arthritis of the upper limbs, as the result of the pharmacotherapy, changes in secretion and composition of saliva, inflammation of the temporomandibular joint and facial deformity. The study summarizes the available literature on the condition of the teeth and periodontal and oral hygiene in the course of JIA. The presence of diverse factors that modify the oral cavity, such as facial growth, functioning of salivary glands, or the supervision and care provided by adults, prevents clear identification if JIA leads to severe dental caries and periodontal disease. Despite conflicting results in studies concerning the clinical oral status, individuals with JIA require special attention regarding disease prevention and maintenance of oral health.
